Objective: In order to efficiently control quality of Ponka

its quality standard was established in this study. Method: Determination of moisture

total ash and ethanol-soluble extract in the crude drug were carried out based on methods recorded in appendix of the 2015 edition of Chinese Pharmacopoeia.The content of total alkaloids was determined by ultraviolet spectrophotometry

using atisine hydrochloride as the reference substance.The content of total flavonol glycoside was assayed by HPLC on a Welch C18 column

quercetin and kaempferol were used as the reference substances. Result: Contents of moisture

total ash

ethanol-soluble extract

total alkaloids and total flavonol glycoside in 17 batches samples were varied in ranges of 7.23%-10.20%

5.94%-18.60%

11.30%-29.40%

0.39%-1.99% and 0.42%-3.09%. Conclusion: These established methods are simple

feasible and reproducible

they can be used for quality control of Ponka.
