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-β-d-xylopyranosyl-olean-28, 13β-olide (1), 11α, 12α-epoxy-3-O-β-d-xylopyranosyl-(1 → 3)-α-l-rhamnopyranosyl-(1 → 2)-β-d-xylopyranosyl-olean-28, 13β-olide (2), and 3-O-β-d-xylopyranosyl-(1 → 3)-α-l-rhamnopyranosyl-(1 → 2)-β-d-xylopyranosyl oleanolic acid 28-O-β-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.
