牛心朴子草化学成份分离

Isolation on the Chemical Constituents From Cynanchum Komarovii Al. Iljinski

从牛心朴子草 ( Cynanchum Komarovii AL.Iljinski)中又分得三个物质 ,据理化常数 ,波谱分析与文献对照 ,鉴定为 1 3.5—二甲氧基— 4—羟基肉桂酸 ,2 3.5—二甲氧基—4—羟基肉桂酸甲酯 ,3反—十八碳烯—〔9〕—酸乙酯。该植物所含上述成份均为首次报导。

Three compounds were isoalted from cynanchum komarovii Al. Iljinski. They were identified as ① 3.5-2 methoxy-4-hydroxy-cinnamic acid, ② 3.5-2 methoxy-4-hydroxy-methyl cinnamate, ③ E-octadecenl-〔9〕-acetate by physical-chemical constsnts and spectral analyses. They are obtained from the plant for the first time.
