(1), a new secoiridoid glucoside with a cyclobutane skeleton and three new acylated secoiridoid glucosides, 2'-(2,3-dihydroxybenzoyl)-gentiopicroside (2), 2'-(2,3-dihydroxybenzoyl)-swertiamarin (3), 3'-(2,3-dihydroxybenzoyl)-sweroside (4), along with two noriridoids (7 and 8) and two known secoiridoid glucosides (5 and 6), were isolated from Gentiana rigescens Franch. The structures of new compounds
Rigenolide A(1),一种具有环丁烷骨架的新的类仲油苷和三个新的酰化的类总糖苷,2'-(2,3-二羟基苯甲酰基)-龙胆苦苷(2),2'-((2,3-二羟基苯甲酰基)-swertiamarin( 3)从龙胆龙胆中分离出3'-(2,3-二羟基苯甲酰基)-苦味子苷(4)以及两个Norididoids(7和8)和两个已知的secoiridoid苷(5和6)。广泛的光谱分析阐明了新化合物的结构。评估分离的化合物的DPPH自由基清除活性。
