枸土化学成分的研究

Studies on the Chemical Constituents of Goutu(Fraxinus insularis)

从台湾产枸土Fraxinusinsularis叶中分得2个新的天然产物，经波谱方法分别鉴定为insularoside-3’-O-β-D-glucoside（Ⅲ）和insularoside－6－O-β-glucosi－（3’→1）-β-D-glucoside（Ⅳ）。

Two new natural compounds were isolated from the lenves of Fraxinus insularis . On the basis of chemical evidences and spectral data, they were identified as insularoside-3'-O-β-D-glucoside (Ⅲ )and insularoside-6-O-β-glucosi- (3' → 1 )-β-D-glucoside (Ⅳ ).
