| Abstract: | AIM： To investigate the chemical constituents of Psammosilene tunicoides W. C. Wu et C. Y. Wu. METHODS： Compounds were isolated by silica gel, Sephadex LH-20 and Rp-C18 column chromatography and the structures were elucidated by ESI-MS, El-MS and NMR methods. RESULTS： Three compounds were isolated and identified as triterpenoid saponins： 3-O-β- D-galactopyranosyl-（1→2）-β-D-xylopyranosyl-（1→3）]-β-D-6-O-methylglucuronopyranosyl-gypsogenin （1）, 2α-hydroxyursolic acid （2）, tormentic acid （3）.CONCLUSION： Compound 1 is a new triterpenoid saponin while compounds 2 and 3 are isolated from this genus for the first time. |
