Aim: This study aims to establish the quality assessment methods of Pollen Typhae. Materials and Methods: High performance liquid chromatography (HPLC) fingerprint analysis, hierarchical cluster analysis (HCA), and principal component analysis (PCA) were used for quality evaluation of Pollen Typhae from different origins together with microscopic identification. Then, the quantity of 43 crude Pollen Typhae samples in the market was collected and analyzed. Results: In true and false test, four False Pollen Typhae samples, 13 Net Pollen Typhae (NPT) samples, and 26 Grass Pollen Typhae (GPT) samples were identified by microscopic identification. In quality test, the amounts and percentages of Qualified Pollen Typhae, Unqualified Pollen Typhae were 24 (55.81%) and 19 (44.19%), respectively with typhaneoside and isorhamnetin-3-O-neohesperidoside determined by HPLC according to China Pharmacopeia. We analyzed 43 samples from 20 regions and established their fingerprints, then selected 31 peaks as characteristic peaks and calculated their relative peak areas. To express the HPLC fingerprints quantitatively, peak 16, 18, 22, 23, and 26 were verified as typhaneoside, isorhamnetin-3-O-neoheptanoside, rutin, quercetin, and isorhamnetin. The similarity of correlation coefficients in chromatogram was 0.954 ± 0.007 and 0.922 ± 0.004 for NPT and GPT, respectively, while 0.67 ± 0.008 for 43 samples. The analysis of HCA and PCA can distinguish true or false, qualified or unqualified of Pollen Typhae. Conclusion: HPLC fingerprint combined with HCA and PCA provides a very efficient and comprehensive method for quality evaluation of Pollen Typhae.
