概述目前银杏叶黄酮甙的生产现况，提出用絮凝剂、ｐＨ值调节、树脂吸附等纯化工艺，对黄酮含量较低的银杏叶进行研究，制备银杏黄酮甙，得率为０．８～１．１％，纯度在２４％～３０％。
The current status of production of flavonoid glycosides in Ginkgo biloba leaves was summarized. The purification process of flavonoid glycosides of Ginkgo biloba leaves was proposed. The flavonoid glycosides with lower flavone content were studied and the yield was 0.8-1 .1%, purity of 24% to 30%.
