Figure 2: Inhibitory effects of ethanol extract of flower (EF) on postprandial plasma glucose after maltose/glucose loading in normal and diabetic rats. Glycaemic response curve in normal rats (a) and diabetic rats (b) after maltose challenge; glycaemic response curve in normal rats after glucose challenge (c). The normal and diabetic rats fasted for 18 h were received maltose/glucose (3g/kg body wt.) and EF at two different doses (100 and 200 mg/kg body wt.). Control animals were given only maltose/glucose plus 50 mg/kg body wt. of acarbose (positive control). Plasma glucose levels were monitored at 0 (fasting), 30, 60, 90 and 120 min. Data are expressed as the mean± SE, n = 6.
