从土槿皮(Pseudolarix kaempferi, Gord.)中分到两个三萜成分, 经化学和光谱方法证明, 其一为具有羊毛甾烷母核的新三萜-3氧代-羊毛甾-7,23,25-三烯-23,26-环氧-27-羧酸, 命名为金钱松呋喃酸(1), 另一个为白桦脂酸(2), 此外, 还分到β-谷甾醇和β-谷甾醇-β-D-葡萄糖苷。

关键词: 紫外分光光度法, 羧酸, 红外分光光度法, 质谱法, 羊毛甾烷, 糖苷, 三萜, 氧杂环化合物, 核磁共振, 豆甾烷类

A new lanostane-type tritepene, pseudolarifuroic acid (I) (3-oxo-lanosta-7,23,25-trien-23,26-epoxy-27-oic acid) was isolated from Tu-Jin-Pi (the root bark of Pseudolarix kaempferi). Betulinic acid, b-sitosterol and b-sitosterol-b-D-glucoside were also isolated.

Key words: ULTRAVIOLET SPECTROPHOTOMETRY, CARBOXYLIC ACID, INFRARED SPECTROPHOTOMETRY, MASS SPECTROGRAPHY, LANOSTANE, GLYCOSIDE, TRITERPENE, OXYGEN HETEROCYCLICS, NUCLEAR MAGNETIC RESONANCE, STIGMASTANES
