Following the characterization of lablabosides A, B, and C, new oleanane-type triterpene bisdesmosides, lablabosides D, E, and F, were isolated from the glycosidic fraction with adjuvant activity obtained from the seeds of Dolichos lablab L. (Leguminosae). Their chemical structures were elucidated on the basis of chemical and physicochemical evidence as follows : 3-O-[α-L-rhamnopyranosyl (1→2)-β-D-galactopyranosyl (1→2)-β-D-glucopyranosiduronic acid]-28-O-[6-O-(3-hydroxy-3-methylglutaroyl)-β-D-glucopyranosyl] 24-epi-hederagenin (lablaboside D), 3-O-[α-L-rhamnopyranosyl (1→2)-β-D-galactopyranosyl (1→2)-β-D-glucopyranosiduronic acid]-28-O-[α-L-rhamnopyranosyl (1→4)-α-L-rhamnopyranosyl (1→2)-β-D-glucopyranosyl] 24-epi-hederagenin (lablaboside E), 3-O-[α-L-rhamnopyranosyl (1→2)-β-D-galactopyranosyl (1→2)-β-D-glucopyranosiduronic acid]-28-O-[α-L-rhamnopyranosyl (1→4)-α-L-rhamnopyranosyl (1→2)-β-D-glucopyranosyl] oleanolic acid (lablaboside F).

Key Word Index - Patrinia scabiosaefolia; Valerianaceae; triterpenoid glycosides; 2'-O-acetyl-3-O-α-L-arabinopyranosyl-hederagenin. From the roots of Patrinia scabiosaefolia, oleanolic acid, hederagenin, 3-O-α-L-arabinopyranosyl-oleanolic acid, 3-O-α-L-arabinopyranosyl-hederagenin, 2'-O-acetyl-3-O-α-L-arabinopyranosyl-hederagenin and a mixture of sitosterol and campesterol-D-glucosides were isolated.

Three triterpenoid prosapogenins tentatively named CP0 (I), CP2a (VI) and CP3a (VIII) have been isolated from the alkaline hydrolysate of the crude saponin obtained from the root of Clematis chinensis Osbeck.On the basis of chemical and physicochemical evidence, they were characterized as follows: I, hederagenin 23-O-α-L-arabinopyranoside; VI, hederagenin 23-O-β-D-glucopyranoside; VIII, olean-12-ene-28-oic acid-3-β,24-diol (4-epihederagenin) 3-O-α-L-rhamnopyranosyl(1-2)-α-L-arabinopyranoside.I and VI are the first examples of 23-O-glycosides of oleanane-type triterpenes to be isolated from nature.Six less polar genuine saponins were isolated and they appeared to be identical with prosapogenins CP4, CP6, CP7, CP8, CP9 and CP10, on the basis of the results of high performance thin-layer chromatography (HPTLC).Keywords - Clematis chinensis; Ranunculaceae; saponin; prosapogenin; hederagenin 23-O-glycoside; 4-epihederagenin 3-O-glycoside; 13C-NMR
