New triterpenoid saponins from Patrinia scabiosaefolia
چکیده انگلیسی

Phytochemical investigation of the methanol extract from the whole plants of Patrinia scabiosaefolia Fisch. resulted in the isolation of four new triterpenoid saponins (1–4) along with six known compounds (5–10). On the basis of spectroscopic and chemical methods, the structures of the new compounds were established as 3-O-β-d-xylopyranosyl-(1→3)-α-l-rhamnopyranosyl-(1→2)-β-d-xylopyranosyl-12β,30-dihydroxy-olean-28,13β-olide (1), 3-O-α-l-rhamnopyranosyl-(1→2)-β-d-xylopyranosyl-12β,30-dihydroxy-olean-28,13β-olide (2), 3-O-β-d-xylopyranosyl-(1→2)-β-d-glucopyranosyl-12β, 30-dihydroxy-olean-28,13β-olide (3), and 3-O-β-d-glucopyranosyl-(1→4)-β-d-xylopyranosyl-(1→3)-α-l-rhamnopyranosyl-(1→2)-β-d-xylopyranosyl-oleanolic acid 28-O-β-d-glucopyranoside (4), respectively. Compounds 1–3 possess a novel 12β,30-dihydroxy-olean-28,13β-lactone aglycone and a 12β-hydroxy substituent that is rarely found in this kind of triterpenoid saponin.
