| Abstract: | Objective To study the triterpenoid saponin from bulbs of Bolbostemma paniculatum.Methods The compound was isolated by repeated silica gel chromatographies and its strcuture was eluci-dated on the basis of physico chemical property and spectral analysis. Results A novel triterpenoidsaponin was isolated and determined as olean 12-en-28-oic acid, 3- {2-O-6-O-(3R)-4-carboxy-3-hydrox-y-3-methyl-1-oxobutyl]-β-D-glucopyranosyl]-β-D-glucopyranosyl] oxy}-2, 16, 23-trihydroxy-28-2-O-α-L-rhamnose (1→2)-α-L-arabinopyranosyl] ester ( I φ. Conclusion Compound I is a novel compoundnamed as dexylosyltubeimoside Ⅲ. |
