ISOLATION AND STRUCTURE ELUCIDATION OF LOW MOLECULAR WEIGHT EXTRACTIVES FROM WOOD OF TRIPLOID POPULUS TOMENTOSA CARR.

摘要：

Phytochemical investigation in aqueous EtOH extractives of Triploid Populus tomentosa Carr. (Salicaceae) wood, by repeated Sephadex LH-20 open column chromatography and Thin Layer Chromatography, resulted in the isolation and purification of two phenolic acids (ρ-coumaric acid (I) and caffeic acid (II)), two flavonoids (apigenin (III) and luteolin (IV)), and three phenolic glucosides (salicortin (V), salireposide (VI) and populoside (VII)). The structure elucidation and determination of the isolated compounds were based on their physiochemical evidences and spectroscopical data.
