Triterpene glycosides from Kalopanax septemlobum. VI. Glycosides from leaves of Kalopanax septemlobum var. typicum introduced to Crimea

摘要

Thirteen known glycosides of hederagenin and oleanolic acid and the three new triterpene glycosides of oleanolic acid- 28-O-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-O-beta-D-glucopyranosyl ester 3-O-beta-D-glucopyranosyl-(1-->4)-O-beta-D-xylopyranosyl-(1-->3)-O-alpha-L-rhamnopyranosyl-(1-->2)-O-alpha-L-arabinopyranoside of oleanolic acid and the 28-O-alpha-L-rhamnopyranosyl-(1-->4)-O-6-O-acetyl-beta-D-glucopyranosyl-(1-->6)-O-beta-D-glucopyranosyI esters 3-O-beta-D-xylopyranosyl-(1--> 3)-O-alpha-L-rhamnopyranosyl(1-->2)-O-alpha-L-arabinopyranoside of oleanolic acid and 3-O-beta-D-glucopyranosyl-(1-->4)-O-beta-D-xylopyranosyl-(1-->3)-O-alpha-L-rhamnopyranosyl-(1-42)-O-alpha-L-arabinopyranoside of oleanolic acid were isolated from leaves of Kalopanax septemlobum var. typicum introduced to Crimea.
