Abstract
Two new triterpenoid pentasaccharides, saxifragifolins C and D, isolated from the aerial part of Androsace saxifragifolia were characterized as androsacenol 3-O-{β-D-xylopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→4)-βD-glucopyranosyl-(1→2)]-α-L-arabinopyranoside}(6) and cyclamiretin A 3-O-{β-D-xylopyranosyl-(1→2)-β-D-glucopyranosyl(1→4)-[β-D-glucopyranosyl-(1→4)-β-D-glucopyranosyl-(1→2)]-α-L-arabinoside}(7). The structures were elucidated by a combination of field desorption mass spectrometry, chemical degradation, and 1H and 13C n.m.r. spectroscopy.This publication has 5 references indexed in Scilit:
