Stigmasterols from pericarp of Sphaerophysa salsula / 中草药

ABSTRACT

Object Isolation and structural determination of the chemical constituents from the 95% ethanol extract of the pericarp of Sphaerophysa salsula (Pall.) DC. Methods To isolate chemical constituents, solvent extraction together with column chromatography was used. Physico-chemical characters and spectroscopic analysis were employed for structural identification. Results Four compounds were identified as 5?-stigmast-3-one (Ⅰ), 5?-stigmast-3, 6-dione (Ⅱ), stigmast-4-en-3-one (Ⅲ), 3?, 6?-stigmast-4-en-3, 6-diol (Ⅳ). Conclusion All these compounds were first isolated from the plants of Sphaerophysa DC.
