TRTTERPENE GLYCOSIDES FROM Cussonia paniculate.I.ISOLATION AND STRUCTURE DETERMINATION OF GLYCOSIDES A,B!,B2,C,D,G2,Hj,AND H2 FROM LEAVES OF Cussonia paniculata

摘要

The 3-OMICRON-beta-D-glucopyranoside of beta-sitosterol(1)and the known triterpene glycosides 3-OMICRON-alpha-L-arabinopyranosides of oleanolic(2a)and ursolic(2b)acids and hederagenin(3),3-OMCIRON-beta-D-glucopyranosyl-(l->2)-alpha-Larabinopyranoside ofoleanolic acid(4),3-OMICRON-alpha-L-arabinopyranosyl-28-OMICRON-alpha-L-rhamnopyranosyl-(1->4)-OMICRON-beta-D-glucopyranosyl-(1->6)-OMICRON-beta-D-glucopyranosides of oleanolic(5a)and ursolic(5b)acids and thenewglycoside28-OMICRON-alpha-L-rhamnopyranosyl-(1->4)-OMCIRON-beta-D-glucopyranosyl-(1->6)-OMCIRON-beta-D-glucopyranoside of 23-hydroxyursolic acid(6)were isolated/mm leaves of Cussonia paniculata(Araliaceae).Their structures were established using chemical methods and NMR spectroscopy.
