鞭柱唐松草化学成分研究

Studies on Chemical Constituents of Smith Meadowrue Root (Thalictrum smithii)

自鞭柱唐松草根 Ｔｈａｌｉｃｔｒｕｍ ｓｍｉｔｈｉｉ分离鉴定了 ４个化合物，２４Ｓ－环菠萝蜜烷－３β，１６β， ２４，２５，３０－五醇－３－Ｏ－（２－Ｏ－β－Ｄ－木糖基）－β－Ｄ－木糖苷（ Ⅰ）、Ａ胡萝卜苷（ Ⅱ）、小檗碱（Ⅲ）和 ５－羟基－ ４’－甲氧基黄酮 ７－Ｏ（６－α－Ｌ－鼠李糖基）－β－Ｄ－葡萄糖苷（ Ⅳ），其中 Ⅰ为－新的天然产物，并应用光谱 和化学方法鉴定了其结构。

From the root of Thalictrum smithii Boivin, a new triterpene glycoside,24S-cycloartane-3β,6β,24,25,30-pentaol-3-O-(2-O-β-D-xylosyl) -β-sitosterol-3-O-β-D-glucoside(Ⅱ),berberine(Ⅲ)and 5-hydroxy-4'-methoxyflavono-7-O-(6-O-a-L-rhamnoayl)-β-D-glucoside(Ⅳ) were isolated.Their structures were determined by spectroscopic and chemical methodes.
