狗枣猕猴桃根化学成分的研究

Studies on Chemical Constituents of Actinidia kolomikta (Rupr. et Maxim. ) Planch.

从长白山产狗枣猕猴桃根中,分离得到两个白色单体。经光谱分析和化学方法鉴定为△~7-豆甾烯醇和具有生物活性的化合物,其结构为2,3-二-O-β-D-半乳糖基-α-D-半乳糖,命名为狗枣三糖。

Two crystalline components Ⅰ and Ⅱ were isolated from the roots of Actinidia kolomikta. I was identified as △~7-stigmasterol and Ⅱ was named β-kolomiktriose and elucidated as 2, 3-di-0-β -D-galactopyranosyl-α-D-galaetopyranose on the basis of spectral data (^(13)NMR, ~1H NMR, IR and EI-MS).
