青钱柳化学成分的研究(Ⅰ)

Studies on the Chemical Constituents of Cyclocarya paliurus (I)

从青钱柳嫩叶的氯仿提取物中分离到两种无色针状结晶,经光谱学和化学分析鉴定为咖啡因(Caffeine,A)和β-谷甾醇(β-sitosterol,B)。均系首次从该植物中分离得到。

Two compounds from the chloroform extract of Cyclocarya paliurus leave were isolated. On the basis of spectral and chemical analysis, their structures were identified as caffeine (A) and β-sitosterol (B). They were first obtained from the plant.
