翠云草中1个新的芳基黄酮

A new flavonoid with an aryl moiety from Selaginella uncinata

研究翠云草Selaginella uncinata全草的化学成分。采用大孔吸附树脂、硅胶、Sephadex LH-20柱色谱以及高效液相色谱等分离方法,从翠云草75%乙醇提取物中分离得到1个黄酮类化合物,根据理化性质和各种波谱技术鉴定该化合物为8-(4-羧基苯氧基)-5,4'-二羟基-7-甲氧基二氢黄酮(1),该化合物为新的芳基黄酮类化合物,命名为翠云草黄酮G。

The present study is to investigate the chemical constituents of the whole plants of Selaginella uncinata. A new flavonoid was isolated from the 75% ethanol extract of Selaginella uncinata by column chromatographies over macroporous resin, silica gel, Sephadex LH-20 and prep-HPLC. The structure was elucidated as 8- [ 4- （carboxyl） phenoxy ] -5,4＇-dihydroxy-7-methoxyflavanone （ 1 ） and named unciflacone G.
