摘要： An HPLC method has been developed for the determination of quercetin,one of flavones,in extract ofGinkgo b1loba L,leaves.Quercetin was separated completely on a Zorbax-ODS column, 250mm× 4. 6mm i.d.,using a mixture of methanol, water and phosphoric acid(55:44. 6:0.4)as mobile phase; with UV detec-tion at 254nm. The results have shown that the recoveries were between 93.3～103.3%andCVwas l.4l%。
