摘要/Abstract

摘要： 从坚龙胆( Gentiana rigescens) 的根中分离得到1 个新的裂环烯醚萜甙, 命名为坚龙胆甙A ( 1) , 以及8 个已知化合物: 龙胆苦甙(2) , 6′- O-β-D-吡喃葡萄糖基-龙胆苦甙(3 ) , 马钱子酸(4 ) , 6′- O-β-D-吡喃葡萄糖基-马钱子酸(5) , 獐牙菜甙(6) , 2′- (邻, 间-二羟基苯甲酰基) -獐牙菜甙(7) , 獐牙菜苦甙(8 ) , 四乙酰开联番木鳖甙(9) 。它们的化学结构通过现代波谱解析得以鉴定。化合物3 , 5 和9 为首次从坚龙胆中分离得到。

Abstract: A new acylated secoiridoidal glucoside, named gentiorigenoside A (1 ), was isolated from the root of Gentiana rigescens (Gentianaceae) , together with eight known compounds, gentiopicroside ( 2) , 6′- O-β- D-glucopyranosyl gentiopicroside (3) , loganic acid (4 ) , 6′- O-β- D-glucopyranosyl loganic acid ( 5), sweroside ( 6 ), 2′-( o, m-dihydoxybenzyl) -sweroside (7), swertiamarin (8) and secologanoside (9) . heir structures were elucidated on the basis of detailed spectroscopic analysis. Iridoidal glucosides 3, 5 and 9 were isolated for the first time from the title plant.

Key words: Gentiana rigescens
