Abstract

This paper presents new resulst of the study about the bark of Oroxylum indicum (L.) Vent, collecting in An Giang provine, Vietnam. Three compounds as oroxylin A 7-O-β-D-glucopyranoside (1), baicalein 7-O-β-D-glucopyranoside (2) and verbascoside (3) were isolated from the ethyl acetate extract. The structures of these compounds have been elucidated by modern spectroscopic methods: NMR and MS.
Keywords: Oroxylum indicum (L.) Vent, Oroxylin A 7-O-β-D-glucopyranoside, Baicalein 7-O-β-D-glucopyranoside, Verbascoside
