Saponins from Chinese folk medicine, "zhu jie xiang fu," Anemone raddeana REGEL.

From the Chinese folk medicine "Zhu jie xian fu" (roots of Anemone raddeana REGEL, Ranunculaceae), two new oleanane-type glycosides, named raddeanosides R8 (1) and R9 (2), were isolated. The structures of 1 and 2 were determined as 3-O-alpha-L-rhamnopyranosyl-(1----2)-O-beta-D-glucopyranosyl- (1----2)-alpha-L-arabinopyranosyl oleanolic acid 28-O-alpha-L-rhamnopyranosyl-(1----4)-O-beta-D-glucopyranosyl-(1----6)-b eta-D- glucopyranoside and 3-O-alpha-L-rhamnopyranosyl-(1----2)-O-beta-D-glucopyranosyl-(1----2)-al pha-L- arabinopyranosyl 27-hydroxyoleanolic acid 28-O-alpha-L-rhamnopyranosyl-(1----4)-O-beta-D-glucopyranosyl-(1----6)-b eta-D- glucopyranoside, respectively.

Saponins from Leaves of Acanthopanax senticosus HARMS., Ciwujia. II. Structures of Ciwujianosides A1, A2, A3 A4 and D3

Further investigation of the chemical constituents of the leaves of Acanthopanax senticosus HARMS. resulted in the isolation of five new triterpenoid saponins, named ciwujianosides A1 (1), A2 (2), A3 (3), D3 (4) and A4 (5).The structures of these saponins were elucidated as follows: 1, 3-O-β-glucopyranosyl-(1->2)-α-arabinopyranosyloleanolic acid 28-O-α-rhamnopyranosyl-(1->4)-β-glucopyranosyl-(1->6)-β-glucopyranosyl ester; 2, 3-O-β-glucopyranosyl-(1->2)-α-arabinopyranosyl-30-norolean-12,20(29)-dien-28-oic acid 28-O-α-rhamnopyranosyl-(1->4)-β-glucopyranosyl-(1->6)-β-glucopyranosyl ester; 3, 3-O-α-rhamnopyranosyl-(1->2)-α-arabinopyranosylmesembryanthemoidigenic acid 28-O-α-rhamnopyranosyl-(1->4)-β-glucopyranosyl-(1->6)-β-glucopyranosyl ester; 4, 3-O-α-arabinopyranosylmesembryanthemoidigenic acid 28-O-α-rhamnopyranosyl-(1->4)-6-O-acetyl-β-glucopyranosyl-(1->6)-β-glucopyranosyl ester; 5, 3-O-β-glucopyranosyl-(1->2)-α-arabinopyranosylmesembryanthemoidigenic acid 28-O-α-rhamnopyranosyl-(1->4)-6-O-acetyl-β-glucopyranosyl-(1->6)-β-glucopyranosyl ester.Keywords: Acanthopanax senticosus; Araliaceae; saponin; Chinese folk medicine; ciwujianoside; oleanolic acid glycoside; noroleanolic acid glycoside; mesembryanthemoidigenic acid glycoside; ciwujia

SELECTIVE CLEAVAGE OF ESTER TYPE GLYCOSIDE-LINKAGES AND ITS APPLICATION TO STRUCTURE DETERMINATION OF NATURAL OLIGOGLYCOSIDES

On treatment with anhydrous LiI, 2,6-lutidine and anhydrous methanol, an ester type glycosyl linkage of acidic tri- and di-terpenes was selectively cleaved without decomposition of a reducing terminal of the resulting sugar moiety to give an anomeric mixture of methyl glycosides along with an aglycone or a pro-aglycone in quantitative yield.In this reaction, no hydrolysis of any other glycoside linkages took place.
