A new secondary metabolite from Korean traditional herb plant hovenia dulcis

Abstract

Investigation of chemical compounds from the butanol soluble layer of the traditional herb Hovenia dulcis has led to the isolation of a new compound, identified as 2-methoxybenzoic acid-5-O-α-L-rhamnopyranoside (1), along with three known compounds, syringic acid-4-O-α-L-rhamnopyranoside (2), syringic acid (3), and vanillic acid (4). Their chemical structures were established from the interpretation of 2D NMR spectroscopic and the high-resolution mass data. © 2018 Natural Product Incorporation. All rights reserved.
