Two new megastigmane O-glucopyranosides from the leaves of Broussonetia papyrifera
摘要:
Two new megastigmane O-glucopyranosides, named (2R, 3R, 5R, 6S, 9R)-3-hydroxy-5, 6-epoxy-β-ionol-2-O-β-D-glucopyranoside (1) and (2R, 3R, 5R, 6S, 9R)-3-hydroxyl-5, 6-epoxy-acety-β-onol-2-O-β-D-glucopyranoside (2) together with six known megastigmanes, were isolated from the leaves of Broussonetia papyrifera (Linn. ) Vent. Their structures were established by chemical methods and spectroscopic techniques including 2D NMR.
