Four triterpene glycosides were isolated from the roots of Pulsatilla chinensis (Bunge) Regel (Ranunculaceae). Two new glycosides, chinensiosides A ( 1a) and B ( 2), were identified as 3- O-[α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl]-28- O-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl]-3β,23-dihydroxylup-20(29)-en-28-oic acid and 3- O-{α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→4)]-α-L-arabinopyranosyl}-28- O-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl]-3β,23-dihydroxylup-20(29)-en-28-oic acid. The other two glycosides were identified as previously known hederasaponin C ( 3) from Hedera helix and glycoside III ( 4) from Pulsatilla cernua. [ABSTRACT FROM AUTHOR] |
