New 3,4-seco-lupane-type triterpene glycosides from Acanthopanax senticosus forma inermis.
Four new 3,4-seco-lupane-type triterpene glycosides (1-4) were isolated from the leaves of Acanthopanax senticosus forma inermis. The structures of 1-4 were established as 11alpha-hydroxy-3, 4-seco-lup-4(23),20(30)-dien-3-oic acid methyl ester 28-oic acid 28-O-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-be ta-D-glucopyranoside, designated as inermoside (1); 1-deoxychiisanoside (2); 24-hydroxychiisanoside (3); and 11-deoxyisochiisanoside (4) by (1)H-(1)H COSY and (1)H-(13)C COSY(HMBC, HMQC) methods and FABMS.
