4 NEW TRITERPENE GLYCOSIDES FROM SCHEFFLERA-BODINIERI ROOTS

Four novel triterpene glycosides named bodinitins A (1), B (2), C (3), and D (4) were isolated from the roots of Schefflera bodinieri. Based on spectroscopic data, especially H-1-H-1 COSY and C-13-H-1 COSY NMR, the structures of the glycosides have been determined as a-D-glucopyr anosyl-(1-->6)]-beta-D-glucopyranoside of demethylisoaleuritolic acid (1), ta-D-glucopyranosyl(1-->6)]-beta-D-glucopyranoside of isoaleurito lic acid (2), ta-D-glucopyranosyl(1-->6)]-beta-D-glucopyranoside of 3- oxo-8-demethylisoaleuritolic acid (3), and ta-D-glucopyranosyl(1-->6)] -beta-D-glucopyranoside of 3-oxoisoaleuritolic acid (4).
