摘要

摘要从透明鳞草(Lepidagathis hyalina)叶甲醇提取物的乙酸乙酯可溶性组分中分离得到一种新的生物活性三萜皂苷m.f. C42H68O13, m.p. 315[ddot]-317°C。经多种光谱和化学分析,其结构为3-β-O-[α- l -鼠李糖吡喃基(1→4)O-β- d -葡萄糖吡喃基]16-α-羟基齐墩-12-烯(13)-28-酸。该新型三萜皂苷对多种植物病原菌和真菌均有抑菌活性。

A New Biologically Active Triterpenoid Saponin from the Leaves of Lepidagathis hyalina nees
Abstract A new biologically active triterpenoid saponin m.f. C42H68O13, m.p. 315[ddot]-317°C was isolated from the ethyl acetate soluble fraction of the methanolic extract of the leaves of Lepidagathis hyalina. Its structure was characterized as 3-β-O-[α-L-rhamnopyranosyl(1→4)O-β-D-glucopyranosyl]16-α-hydroxy-olean-12-en(13)-28-oic acid by several spectral and chemical analysis. This new triterpenoid saponin showed antimicrobial activity against various plants pathogenic bacteria and fungi.
