[Studies on chemical constituents from the stems of Schisandra sphaerandra].
OBJECTIVE
To investigate the chemical constituents from the stems of Schisandra sphaerandra.


METHODS
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.


RESULTS
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.


CONCLUSIONS
Three pentacyclic triterpene carboxylic acid (5-7) were isolated from Schisandreae for the first time.
