PHENOLIC COMPOUNDS FROM STEM OF BOERHAVIA ERECTA L. GROWING IN VIETNAM

Abstract

Plants of Boerhavia genus (Nyctaginaceae family) are known to have medicinal properties as antidiabetic, immunomodulatory effect, anticonvulsant, antistress, adaptogenic, hepatoprotective activity. Rotenoids in plants of this genus are reported as a new class of potent breast cancer resistance protein inhibitors.[5] Boerhavia erecta L. was used in traditional African medicine but there are still no scientific research in Vietnam where it is widely grown. In this paper, we report the isolation of four compounds: 2,6-dimethoxybenzoquinone (1), (+)-catechin (2), isorhamnetin 3-O-β- D-glucopyranoside (3) and rutin (4). The structure of these compounds were determined through the interpretation of their MS and 1D, 2D-NMR data. This is the first time that these compounds are isolated from Boerhavia erecta L.
