Abstract
Borreria is a genus of Rubiaceae widespread in tropical and subtropical America, Africa, Asia, and Europe. Studies have confirmed that extracts as well as some isolated compounds of species of Borreria genus possess diverse biological activities, including anti-inflammatory, antitumor, antimicrobial, antioxidant, anti-ulcer… In this paper, we present the chemical structures of four compounds isolated from Borreria alata, collected at Di Linh district, Lam Dong province, Vietnam. 3β, 6β, 23-trihydroxyurs- 12-en-28-oic acid (1), sodium deacetylasperulosidate (2), 7β-hydroxy-11-methylforsythide (3) and sodium loganate (4). Among them, three compounds (1), (2), (3) were known for the first time in Borreria genus to our best knowledge and (4) is a new compound. The chemical structures of these compounds wereelucidated by analysis of 1D and 2D NMR and HR-MS spectroscopic data, as well as by comparison with those reported in the literature.
