Abstract: Four oleanane-type triterpenoid saponins were isolated from the roots of Psammosilene tunicoides W. C. Wu et C. Y. Wu. Their structures were elucidated on the basis of spectral and chemical evi-dence as 3-O-β-Dgalactopyranosyl-(1→2)-β-D-6-O-methylglucuronopyranosyl quillaic acid(1),3-O-β-D-galactopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucuronopyranosyl quillaic acid(2),3-O-β-D-galactopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-6-O-methylglucuronopyranosylquillaic acid (3),3-O-β-D-galactopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-6-O-ethylglucuronopyranosyl quillaic acid(4)。
