[Studies on chemical constituents from the stems of Schisandra sphaerandra].Zhongguo Zhong Yao Za Zhi. 2003 Feb; 28(2):138-40.ZZ
To investigate the chemical constituents from the stems of Schisandra sphaerandra.
Compounds were isolated from ethanolic extract of the titled herb by silica gel column chromatography, and their structures were elucidated by physical and chemical evidences and spectroscopic analysis.
12 compounds were obtained and identified as wuweizisu C (1), ganwuweizic acid (2), nigranoic acid (3), catechin (4), 2 alpha,24-dihytroxyursolic acid. (5), 3 beta-O-acetylursolic acid (6), ursolic acid (7), slyceryl 26-hydroxyhexacosanoate (8), slyceryl hexacosanoate (9), fat acids (10), beta-sitosterol (11), daucosterol (12), respectirely.
Three pentacyclic triterpene carboxylic acid (5-7) were isolated from Schisandreae for the first time.
