July-September 2009, 5(19):238-248
Currently, no standard protocols and objective measures are existing in present system for quality analysis of herbal sunscreens. Present work is an attempt to compile rapid, non-invasive technologies to investigate the sunscreens containing various herbs like aloe vera, jojoba, cucumber, wheat germ, olive etc for their efficacy in protecting skin from UVA and UVB sunrays. Commercial herbal sunscreens containing herbs aloe vera, basil, green tea, etc and bearing SPF range 10-40 coded as HS1- HS14, were analyzed by subjective, photostability and other parameters evaluation. All sunscreens shown pH [6.09±0.01 to 8.30±0.03], Saponification value [6.01±0.2 to 207.57±0.3], Acid value [1.56±0.6 to 17.27±0.5], Ash value [0.01±1 to 0.08±2 gm], Spreadibility [96±0.9 to 98±0.9 %], Layer thickness [28.99±1.55 to 32.25±1.00 %]. Viscosity profile showed the pseudoplastic behaviour of all formulations. Phase separation was observed in HS1 to HS4, HS7& HS9 to HS12 during stability study. None of them were found to be irritant [erythema score = 0] and have microbial count load in the range of to 31±1 to 34±2 CFU/gm. 98±5 % of all sunscreens has shown SPF as per labelled claim by In-vitro and In-vivo method. HS 6, 9, 11 were found to be unstable in UVA range. HS8, most preferred by volunteers after Psychometric evaluation. Results of the study scientifically verified that herbs are having enough potential to protect skin to protect skin from harmful sunrays and it is worthwhile for consumers to use herbal sunscreens. Overall study is useful to substantiate product claims.

WD Ratnasooriya, TSP Fernando
July-September 2009, 5(19):260-265
This study examined the gastric ulcer healing potential of black tea (Camellia sinensis) using Sri Lankan high grown Dust grade No: 1 black tea in rat acetic acid-induced gastric ulcer model. Three oral doses (84, 167 or 501 mg/ml) of black tea brew (BTB) made according to ISO recommendations were used in the evaluation of gastric ulcer healing activity. The results showed a significant (P < 0.05) and dose-dependent gastric ulcer healing activity (in terms of reduction in gastric ulcer area). This effect had a rapid onset (with in 14 days). The gastric ulcer healing activity of BTB was however inferior (by 9 fold) to omeparazole, the reference drug. BTB displayed in vitro antioxidant activity (using DPPH assay; by 2985-3923 Trolox equivalents ìg/l), and also inhibited in vitro nitric oxide production (3-78 %). In addition, BTB had antihistamine activity (by wheal test; by 33.5%) and increased the gastric pH (from 3.3 to 5.9) and impaired the gastric acid output (by 69%). It is concluded that black tea possessed strong, oral gastric ulcer healing activity which is mediated via multiple mechanisms.

S Chandrakala C Karthik, Venkatasubramanian Padma
July-September 2009, 5(19):272-278
Tubers of Ipomoea mauritiana that are used as Vidari in Ayurveda are important ingredients in popular Ayurvedic nutraceutical products such as Chyavanprash. The objective of the current study was to develop distinct phytochemical and microscopy protocols and standards that can be used in quality control of the crude drug. Chromatographic analyses of methanol extracts of the tuber gave typical fingerprints, where Scopoletin, a standard reference marker, resolved at Rf 0.56 under TLC and at Rt 21.5 min under HPLC conditions. Three bright blue fluorescent bands at Rf 0.70, 0.56 and 0.45 under the TLC conditions were characteristic of the raw drug. Scopoletin was quantified to be 0.029-0.034 % using the HPTLC and HPLC methods. Powder microscopic features of authentic tubers of Ipomoea mauritiana were characterized by the presence of cluster crystals, simple and compound starch grains with a range of 10-50 µm and orangish-brown cell fragments of laticiferous elements. Longitudinal sections showed the laticifers (latex cells) of articulated anastomosing type and the transverse section of the tubers were mostly characterized by the specific successive cortical cambial activity.

Lal Gupta Girdhari, Chand Rana Avtar
July 2009, 5(19):46-50
The possible synergism between WS and dopamine precursor L-dopa to inhibit haloperidol-induced catalepsy was investigated by using standard bar test in mice. The effect of WS (20-200 mg/kg, oral), L-dopa (20-200 mg/kg, oral) plus carbidopa and combination of subeffective doses of WS (20 or 50 mg/kg, oral) prior to L-dopa (20, 50 or 100 mg/kg, oral) plus carbidopa was assessed in haloperidol (1 mg/kg, i.p.) induced catalepsy. L-dopa and carbidopa combination was always administered in 10:1 ratio. WS (100 or 200 mg/kg, oral) and L-dopa (50, 100 or 200 mg/kg, oral) plus carbidopa treated groups showed a dose dependent reduction in cataleptic scores. Subeffective doses of WS (20 or 50 mg/kg, oral) prior to L-dopa (20, 50 or 100 mg/kg, oral) also potentiated the anticataleptic effect of L-dopa. These results indicate that subeffective doses of WS enhance the anticataleptic actions of L-dopa and the possibility of using WS as adjunctive therapy to reduce the doses and the adverse effects of dopamine precursor in Parkinson's disease.

July 2009, 5(19):69-73
The present study was undertaken to evaluate antistress and immunomodulatory activity of aqueous extract of Momordica charantia (MC). Antistress activity was evaluated by measuring the swimming time in mice and cold immobilization induced stress for 10 days in rats, using Withania somnifera (100mg/kg) as reference standard. Immunomodulatory activity was evaluated by carbon clearance assay and percentage adhesion of neutrophils to nylon fibers using Levamisole as reference standard. The degree of protection was determined by measuring gastric ulceration, adrenal gland and spleen weights and by measuring levels of serum glucose, AST and ALT. Swiss albino mice of either sex were divided into 4 groups such as normal control, MC lower dose (450 mg/kg, p.o), MC higher dose (900 mg/kg, p.o) and standard group, treated with standard drug Levamisole (50 mg/kg, p.o). MC increased the swimming time in mice significantly (P<0.001) and the results are comparable to that of standard Withania somnifera. MC has also significantly (P<0.001) reversed the cold immobilization induced changes in glucose, AST, ALT, ulcer score, weight of adrenal gland and spleen. MC improves the phagocytic index in a dose dependent manner. MC at higher dose significantly (P<0.001) increased the percentage of adhesion of Neutrophils to nylon fibers when compared with the normal control animals. The results were comparable with that of standard drug levamisole. Momordica charantia has significant antistress, immunomodulatory activity.

July-September 2009, 5(19):249-253
The present study was aimed at improving the content of therapeutically active principle, andrographolide and whole plant biomass of Andrographis paniculata (Burm. F.) Wall.Ex Nees, by foliar application of plant growth regulators. The pot cultured plants were treated with Gibberellic acid (GA3), Indole acetic acid (IAA), Naphthalene acetic acid (NAA) and Benzyl amino purine (BAP), in the concentration of 25, 50, and 100mg/l each. The plants sprayed with distilled water were maintained as control. The foliar application of these growth regulators was initiated at 30 DAT and continued upto flowering stage at an interval of 10 days. The HPLC analysis revealed that, application of IAA-50mg/l was very effective to enhance the andrographolide content (45%), which was followed by NAA-50mg/l (37%) over control. The whole plant biomass (Panchang) of Andrographis is used in medicine and hence fresh and dry biomass was also determined. The results indicated that NAA (Fresh Weight: 221%, Dry Weight: 155%) and IAA (Fresh Weight: 215%, Dry Weight: 120%) emerged out as the best treatments for improving fresh and dry biomass over control. The treatments of IAA and NAA (50mg/l) were found to be most effective for improving whole plant biomass as well as andrographolide content which can be recommended for the growers.

DP Dissanayake, DTU Abeytunga, NS Vasudewa, WD Ratnasooriya
July-September 2009, 5(19):266-271
The inhibition of lipid peroxidation by Pleurotus ostreatus was established using Thiobarbituric (TBARS) assay. Three solvent extracts of P. ostreatus namely, the acetone, dichloromethane and hexane extracts were used. All three extracts showed inhibition of lipid peroxidation. The antioxidant indexes at 1.25 mg/ml concentration of acetone, dichloromethane and hexane were 38%, 43% and 36% respectively. Ergosterol was isolated and characterized from the dichloromethane extract. The antioxidant index of ergosterol at 1.25 mg/ml was 73% when tested using the same method. There exist a possibility that ergosterol can inhibit the peroxidation of common fatty acids present in egg yolk substrate (which was used for TBARS assay). The relative susceptibilities for peroxidation of ergosterol, linoleic acid and linolenic acid were investigated using computational calculations. It was found that the addition of an oxygen molecule to ergosterol is kinetically much more feasible than the addition of the same to linoleic or linolenic acids. The energy barriers for peroxidation with triplet oxygen at HF/3-21 G level of theory for ergosterol and linoleic acid (trans, trans) were 231.85 kJmol1 and 420.52 kJmol-1 respectively. It was also found that the former reaction is thermodynamically less favorable compared to the latter. The results from theoretical investigation support the experimental observation of the capability of lipid peroxidation inhibition by ergosterol.

We have investigated the effect of Nyctanthes arbortristis (50, 100, 200 mg/kg) and Calotropis gigantea leaves and flower chloroform (10, 20, 50 mg/kg) and Calotropis gigantea flower petroleum ether extracts (10, 20, 50 mg/kg) in high-fructose diet induced insulin resistance in rats. The fasting serum glucose, insulin, triglyceride and cholesterol levels were measured in blood serum for 27 days of treatment. The fasting serum glucose, insulin, insulin resistance index (FIRI) levels of high-fructose diet (control) rats significantly (P<0.001 vs. normal) increased, like wise, serum triglyceride, cholesterols significantly (P<0.001-P<0.01 vs. normal) increased. The Nyctanthes arbortristis and Calotropis gigantea leaves and flower treatment prevent significantly (P<0.001-P<0.01) vs. control) increase serum glucose, insulin, levels in high fructose-diet treated rats, except in glucose Calotropis gigantea leaves 50 mg/kg, while significantly (P<0.05-P<0.01 vs. control) decreased in triglyceride, cholesterol, except in triglyceride Nyctanthes arbortristis leaves 50 mg and in cholesterol Nyctanthes arbortristis leaves and flowers 50 mg. Further more, high-fructose diet (control) had higher in FIRI (P<0.001) than normal. In contrast, Nyctanthes arbortristis and Calotropis gigantea significantly (P<0.001) decreased FIRI in the high-fructose diet treated rats.

July-September 2009, 5(19):254-259
The extract of root bark of Salacia oblonga (SO) belonging to the family Celastraceae was tested for the anti-mutagenic activity using sperm abnormality test in Wistar rats. The hydroalcoholic extract (0.5 and 1 gm/kg, b.w, p.o. daily for 7 days) was evaluated against Mitomycin-C (MMC-2 mg/kg, b.w, i.p.) induced testicular toxicity by estimating the sperm shape abnormality and sperm count. The sampling was done after 48 hours and 72 hours of the clastogen treatment. The antioxidant activity of the SO was evaluated by measuring the serum levels of superoxide dismutase(SOD) and catalase. The results indicated that prior treatment of SO had suppressed the changes produced by MMC. SO at a dose of 1.0 gm/kg bw had shown significant (p<0.01) inhibition in the sperm shape abnormality and sperm count in both the time intervals, while the lower dose (0.5 gm/kg, b.w) showed inhibitory effect mainly at 48 hr duration compared to the MMC group. The results also indicated that SO has improved (p<0.01) the status of serum antioxidant enzymes compared with the MMC group. The data from the study suggests that SO possess antimutagenic effect against MMC and the activity could be due its antioxidant potential.

July 2009, 5(19):11-14
Cardiovascular diseases are becoming an increasing problem worldwide and hypercholesterolemia has been correlated for coronary heart diseases. Currently available hypolipidemic drugs have been associated with number of side effects. Herbal treatment for hyperlipidemia poses no side effects and is relatively cheap and locally available. In view of this, the present study was carried out to investigate the effect of gum ghatti of Anogeissus lalifolia on serum lipid levels of albino rats. Rats were made hyperlipidemic by the oral administration of cholesterol (400mg/kg body weight/day) along with cholic acid (50mg/kg) in coconut oil. The hypolipidemic effect was compared with control. The rats were divided into six groups of six animals each. In atherogenic diet induced hyperlipidemic model, the rats receiving treatment with gum ghatti at 250 mg/kg dosage showed significant reduction in serum triglyceride (82.75±0.63) only and there was no significant changes either in serum total cholesterol or elevation in HDL. Whereas, at 500 and 750 mg/kg dosage showed significant reduction in serum total cholesterol (72.85±0.60, 68.17±0.95) and serum triglyceride (78.92±0.34, 75.93±1.05). Further, the 750 mg/kg dose has also exhibited significant elevation in high density lipoprotein cholesterol (41.13±0.37).

Anti-inflammatory and wound healing potential of Prosthechea michuacana in rats
Rosa Martha Perez Gutierrez, Rosario Vargas Solis
July-September 2009, 5(19):219-225
The hexane, methanol and chloroform extracts of bulbs of orchid Prosthechea michuacana (PMIC) were studied for their wound healing and anti-inflammatory properties. Wound healing effects were studied on incision (skin breaking strength), excision (percent wound contraction). Collagen, hexosamine, total protein and DNA content in the granulation tissues were determined in addition to the rates of wound contraction and period of epithelialization. Topical applications of hexane extract PMIC produced increases in tensile strength, collagen content (hydroxyproline), and is better epithelisation thereby facilitating the healing. The hexane extract also was found possess significant anti-inflammatory activity in both acute (carrageenin-induced edema) as well as subacute (cotton pellet) animals models. Thus it could concluded that PMIC hexane may enhance the process of wound healing by influencing phases such as inflammation, fibroplasias, collagen synthesis and maturation, and wound contraction. Hexane extract significantly inhibited later phase of edema so it seems possible that P. michuacana blocks prostaglandins and cyclooxygenase release in later phase of acute inflammation, consequently decrease in granuloma weight indicates the suppression of the proliferative phase, which was effectively inhibited by the PMIC.

Annan Kofi, Gbedema Stephen, Adu Francis
July 2009, 5(19):119-123
Twelve fatty acids identified from the methanol extract of Paullinia pinnata L. root extract by the use of Gas Chromatography coupled with mass spectrophotometer were screened for antibacterial activity against both Gram positive and Gram negative bacteria as well as three resistant strains of Staphylococcus aureus SA1199B, XU212 and RN4220 resistant to norfloxacin, tetracycline and erythromycin respectively. Using the 96-well microtitre plate method, azelaic acid (a dicarboxylic acid), showed the highest activity against all organisms tested with minimum inhibitory concentration range of 32-256 μg/ml while palmitic, oleic, eicosanoic and stearic acids also showed weak to moderate activity against Staph. aureus, B. subtilis, E. coli and P. aeruginosa. However, docosanoic, tetradecanoic and eicosenoic acids had no activity against all organisms tested. The results also indicated that while the crude methanol extract possess potent antioxidant activity by bleaching DPPH radical (IC 50 of 3.8μg/ml), the fatty acids did not show any significant radical scavenging action.

July 2009, 5(19):15-18
In the present study selected medicinal plant samples used in the preparation of Indian herbal medicinal products were analysed, after nitric acid digestion, for the content of cadmium, mercury and lead, by atomic absorption spectrophotometry. The samples are procured by three method.1.Self collected from medicinal plant garden with the help of experts.2.Purchased from local drug collectors.3. Purchased from raw material stores. Result shows that 33% of sample analysed were contain toxic levels of cadmium, 40% were contain toxic levels of lead and no sample posses arsenic above the limit. (limit of cadmium, mercury and lead were 0.3,0.5 and 10 μg/g, respectively) PRACTICAL APPLICATIONS Plants can contain heavy metals from their presence in the soil, water or air. High levels of toxic metals can occur when the plants are grown in polluted areas, such as near roadways or metal mining and smelting operations. In addition, high levels can be found when agricultural expedients are used, including Cadmium containing fertilizers, organic mercury or lead based pesticides, and contaminated irrigation water. Quality has to be built into the whole process beginning from the selection of starting material to the final product reaching the consumer. In the present study were carried out, to evaluate the quality and safety of crude drug. The result shows that Indian herbal drug industry needs to ensure procurement of standardized authentic raw material free from toxic contaminants. Such approaches remain important in global promotion of medicinal plants & herbal medicinal products from India.

Carbon tetrachloride was selected as hepatotoxin. Silymarin was the reference hepatoprotective agent. In the in vivo study, serum transaminases, alkaline phosphatase, total bilirubin, total cholesterol, albumin together with total protein and histopathological examination were the criteria for the evidences of liver injury. Carbon tetrachloride caused the alterations in all the biochemical parameters and centrilobular necrosis. Among the Ethyl methyl ketone and methanol sub-fractions tested (50, 100 and 150 mg/kg), methanol sub-fraction (150 mg/kg) of the bio-active total methanol extract and silymarin (100 mg/kg) enhanced liver cell recovery by restoring all the altered biochemical parameters back to normal. In the in vitro study, release of transaminases, total protein together and hepatocyte viability were the criteria. Primary cultures of hepatocytes were treated with carbon tetra chloride (10 μl/ml), and various concentrations (100, 500 and 1000 μg/ml) of ethyl methyl ketone and methanol sub-fractions of total methanol extract and silymarin (100 μg/ml). Carbon tetrachloride reduced the hepatocyte viability and also altered the biochemical parameters, which were restored significantly (P<0.05) by ethyl methyl ketone (1000 μg/ml) and methanol (500 and 1000 μg/ml) sub-fractions. These results suggest that Baliospermum montanum possess the hepatoprotective activity against carbon tetrachloride induced liver injury in both rats and primary cultures of rat hepatocytes.

July 2009, 5(19):1-10
Hexane, ethanolic and aqueous extracts of Talinum portulacifolium leaves were prepared and given individually at different doses to normal and streptozotocin (STZ) induced diabetic rats after an overnight fast. The blood glucose levels were measured at 0,1,2,3,4,5 and 6 h after the treatment. The hexane extract at a dosage of 0.5g/kg b.w has shown maximal blood glucose lowering effect (64.7%) in diabetes rats. The same dosage did not produce any hypoglycemic activity in normal rats. The antihyperglycemic activity of hexane extract of Talinum portulacifolium leaves was significantly higher than that of glibenclamide, an oral hypoglycemic agent. All the extracts exhibited dose dependent scavenging activities against 2,2-diphenly-1-picrylhydrazyl (DPPH) radicals, nitric oxide radicals and hydrogen peroxide. Further, all extracts had relatively lower reducing power, compared to that of ascorbic acid. The total phenolic content of hexane, ethanol and aqueous extracts were found to be 61, 100 and 114 mg/gm of the dry extract respectively. TLC of the above extracts using the DPPH as a spraying reagent revealed yellow spots against purple background indicating the presence of potent antioxidant compounds. In conclusion hexane extract of Talinum portulacifolium leaves possess both antihyperglycemic and antioxidant activites, while the ethanol and aqueous extracts possess only antioxidant activity.

Anthocyanins (ACN) are part of a large and wide spread group of plant constituents known collectively as flavanoids. In the present research work anthocyanins were extracted from Ficus racemosa fruit. Family: Moraceae, using acidified methanol (1% HCL in methanol). The extracted anthocyanins were isolated and purified using the Amberllite - XAD4 resin. Anthocyanins were characterized by means of Chromatographic and Spectral data obtained from HPLC and UV Spectroscopy. Two major pigments identified were Peonidin -3-glucoside and Pelargonidin -3-glucoside. Peaks for anthocyanins, which are present in very low amount, and in less concentration, can be verified by means of commercially available external standards. The samples were diluted in the mixture of methanol and formic acid just before the injection on the column and separated on Lichrospher-100 Reversed phase C18 end capped column (5 micron) 125mm x 4mm using gradient solvent system consisting of 5Mm of phosphoric acid and acetonitrile . DAD detector was employed at 520 nm for anthocyanins. An Ficus racemosa fruit anthocyanosides preparation (equivalent to 30% of anthocyanidins) demonstrated significant vasoprotective effect in rabbits, the skin capillary permeability increase, due to chloroform, was reduced after i.p. (25-100 mg/kg) anthocyanosides. Comparison was made between the action of the methanol extract and a known protective microvascular drug proxerutin (25 mg/kg). The mixed of anthocyanosides was more active that the proxerutin.

July-September 2009, 5(19):226-231
A study to evaluate the gastroprotective activity of hot water extract (HWE) of Alpinia calcarata Roscoe (Zingiberaceae) rhizomes was carried out. Three doses (500, 750, 1000 mg/kg) of HWE was evaluated for gastroprotective activity against ethanol induced gastric ulcers in rats. Oral administration of HWE provided dose dependent (r2 = 0.98) and significant (P< 0.05) protection against gastric damage caused by ethanol. The gastroprotective effect of HWE was superior to that of cimetidine, the reference drug. The HWE significantly (P< 0.05) inhibited gastric volume, acidity (total and free) and significantly (P< 0.05) increased the gastric pH. On the other hand, gastric mucosal secretion remained unaltered. Further, HWE possessed significant (P< 0.05) antihistamine activity. The HWE was well tolerated: no overt signs of toxicity, hepatotoxicity (in terms of aspartate transaminase, alanine transaminase) or renotoxicity (as judged by serum urea and creatinie). It is concluded that HWE of A. calcarata rhizome has strong and safe gastroprotective activity.

July 2009, 5(19):32-35
A questionnaire survey for the analysis of determinants influencing use of Ayurvedic medication was conducted amongst 2000 people from various categories approached at fifty different medical stores in Pune region, asking them to tick the option that they consider while using Ayurvedic medication. Results were calculated using descriptive analysis. 37.30% of people regularly consume Ayurvedic medication up to 50% of their total medication, wherein safety (52%) and faith (33.50%) were found to be the prime reasons for its consumption. The study also found that 58.45% of surveyed people follow physician's prescription and don't accept substituted medicine given by the chemist. A comparatively large number of people (41.55%) go for self medication influenced by various parameters. The use of Ayurvedic medication in pediatric patients and co- administration with allopathic medicine by qualified people is fairly less. The survey revealed that consumption of Ayurvedic medication in Pune region is increasing, wherein safety and faith are important parameters, however, like allopathic medication; people usually stick to the prescription issued by the physician. The increasing trend of self medication and lack of knowledge of herb drug interaction especially in non graduates are the major concerns need to be addressed for better outcome of the therapy.

AS Jain, SJ Surana
July 2009, 5(19):100-104
Gymnosporia rothiana is used in Indian folk medicine as an antiulcerogenic agent. Despite of its promising use, there has been no scientific report present regarding its antiulcer activity. Therefore, this study was intended to evaluate the antiulcer property of various extracts of leaves of Gymnosporia rothiana at different dose levels in ethanol induced and indomethacin induced gastric ulcer models. It was observed that oral administration of all the extracts shows significant reduction in ulcer lesion index as well as increase in volume and pH of gastric content in both experimental models, being petroleum ether extract the most effective at dose of 250 mg/kg; it significantly reduced gastric lesion index (70.06%), in comparison to omeprazole (71.20%) and methanolic extract at a dose of 500 mg/kg (67.22%). Increased gastric mucosal defense mechanism by petroleum ether extract is probably due to its high levels of terpenoids like β amyrin, lupeol, friedelin. The present results clearly shows antiulcer effect of Gymnosporia rothiana against various irritants has been mainly due to cytoprotective effect mediated through prostaglandin and partly due to free radical scavenging activity.
