Objective: To establish a quantification method for quercetin and kaempferol in the leaves of Phyllanthus emblica by HPLC. Method: HPLC is applied on the determination of quercetin and kaempferol in the leaves of P. emblica with C18 column(4.6 mm×250 mm
5 μm) and a mixture of acetonitrile-0.1% phosphoric acid (27:73) as a mobile phase with the flow rate at 1.0mL·min-1. Quercetin and kaempferol were detected at 360nm
column temperature was set at 30 ℃. Result: Quercetin and kaempferol were linear in the range of 0.06~1.2 μg and 0.021~0.43 μg. The average recovery of quercetin and kaempferol was 98.83% with RSD 2.73% and 101.58% with RSD 2.21% (n=6) respectively. Conclusion: The method can be applied to the quality control of the leaves of P. emblica L.
