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 1H−H
COSY
and 13C−1H COSY NMR, the structures of the
glycosides have been determined as 28-O-[α-l-rhamopyranosyl-(1→4)-O-β-d-glucopyranosyl-(1→6)]-β-d-glucopyranoside
of demethylisoaleuritolic acid (1),
28-O-[α-l-rhamopyranosyl(1→4)-O-β-d-glucopyranosyl(1→6)]-β-d-glucopyranoside
of isoaleuritolic acid (2),
28-O-[α-l-rhamnopyranosyl(1→4)-O-β-d-glucopyranosyl(1→6)]-β-d-glucopyranoside of 3-oxo-8-demethylisoaleuritolic acid (3),
and
28-O-[α-l-rhamopyranosyl(1→4)-O-β-d-glucopyranosyl(1→6)]-β-d-glucopyranoside
of 3-oxoisoaleuritolic acid (4).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
