Phenolic glucosides from Alangium plantanifolium.
A novel phenolic glucoside alangitanifoliside A (1) together with two known phenolic glucosides 4',6'-O-(S)-hexahydroxydiphenylsalicin (2) and salicin (3), and gallic acid were isolated from stem barks of Alangium plantanifolium. Their structures were determined by spectroscopic and chemical methods. The structure of 1 was elucidated to be 1-O-[2-(1-hydroxy-6-oxocyclohex-2-ene-1-carboxymethyl)-phenyl]-4,6-O-[(S)-,4,4',5,5' 6,6'-hexahydroxydiphenoyl]-beta-D-glucopyranose.
