Abstract

The isolation of lignan J, C~28~H~34~O~13~, a new compound from the roots and rhizomes of American Podophyllum peltatum L. and Indian P. emodi Wall. is described. Lignan J is easily cleaved to desoxypodphyllotoxin and D‐glucose. By degradation of its penta‐phenylurethane, the structure of lignan J has been deduced as the 1β‐D‐glucopyranosylester of desoxypodophyllinic acid. It is suggested that glucose esters of this type may act as intermediates in the biogenesis of lignans.
