摘要
从假鹰爪(Desmos chinensis Lour.)茎皮乙醇提取物的非生物碱部分得到5个黄酮类成分,其中1个为新的双氢黄酮,命名为假鹰爪素A(cochinine A),经波谱分析,其结构测定为5-羟基-6-甲酰基-7-甲氧基-8-甲基双氢黄酮(1)。同时,还鉴定了其中的desmethoxymatteucinol(Ⅱ),negletein(Ⅲ)及lawinal(Ⅳ)。此外,还探讨了该类黄酮成分在化学分类上的意义。
Five flavonoids were isolated from the stem of Desmos chinensis Lour., of which three were identified as desmethoxymatteucinol(Ⅱ), negletein(Ⅲ)and lawinal(Ⅳ) respectively. The structure of new dihydroflavone named cochinine A, was elucidated as 5-hydroxy-6-formyl-7-methoxy-8-methyl dihydroflavone(Ⅰ) by means of spectroscopic analysis. The chemotaxonomy feature of these flavonoids was also approached.
