摘要
从湖北安陆产的银杏叶中分离出一种黄酮甙(Ⅰ),将其进一步水解,纯化,所得产物经红外光谱、紫外光谱、熔点等检测,结果表明这种黄酮甙元是槲皮素(Ⅱ),(Ⅰ)经熔点和定性检测推测为:3 O α(6p 香豆酰葡萄糖基 ( 1,4 鼠李糖甙)槲皮素.
A flovonoid glycoside was isolated from the leaves of ginkgo biloba planted in Anlu city of Hubei province, Its structure elucidated as quercetin3O(6pcoumaroilglucosylβ1,4rhamnoside) (Ⅰ).Upon acid hydrolysis of I, filtering and purifying, the product that was identified by IR, UV and mp.was quercetin.
