Abstract

Four new furostanol saponins (1-4), two pairs of diastereoisomers, were isolated from methanolic extracts of Tupistra chinensis rhizomes and their structures were assigned from (1)H and (13)C NMR spectra, DEPT, and by 2D COSY, NOESY, HMQC, and HMBC experiments.

摘要

从开口箭根茎的甲醇提取物中分离出四种新的呋甾烷醇皂苷（1-4），它们是两对非对映异构体，其结构通过¹H和¹³C NMR光谱、DEPT以及二维COSY、NOESY、HMQC和HMBC实验确定。
