Arbutin Derivatives from the Seeds of Madhuca latifolia

Abstract

A new arbutin derivative, madhuglucoside (1), along with three known arbutin derivatives were isolated from the seeds of Madhuca latifolia in addition to seven other known constituents. Their structures were established on the basis of spectral analysis. Compounds 1a, 2a and 3a were obtained in a pure state after acetylation of the mother fraction and characterized as their acetyl derivatives.
