Phytochemical investigation of methanol extract from the whole plants of Patrinia scabiosifolia Fisch. resulted in the isolation of three new triterpenoid saponins (1-3) along with twelve known triterpenoids (4-15). The structures of the new compounds were established as 11α, 12α-epoxy-3-O-ß-D-xylopyranosyl-olean-28, 13ß-olide (1), 11α, 12α-epoxy-3-O-ß-D-xylopyranosyl-(1 → 3)-α-L-rhamnopyranosyl-(1 → 2)-ß-D-xylopyranosyl-olean-28, 13ß-olide (2), and 3-O-ß-D-xylopyranosyl-(1 → 3)-α-L-rhamnopyranosyl-(1 → 2)-ß-D-xylopyranosyl oleanolic acid 28-O-ß-D-glucopyranoside (3) on the basis of various spectroscopic analyses (including different 1D and 2D NMR spectroscopies and high-resolution electrospray ionization mass spectrometry) and chemical evidences.
