英文摘要: Boussingaultia gracilis Miers var. pseudobaselloides Bailey (Basellaccae) is a folk medicine used as an analgesic and supplements, only a few research was reported on the chemical constituents of this plant. This paper presented its chemical and anti-HIV active constituents. By column chromatography (Silica and Sephadex LH-20 gel) methods, two flavanols and four flavones were isolated from the 70% (volume fraction) ethanol extract. Based on extensive spectral analysis (UV, IR, MS and 1D, 2D NMR), compounds 1-6 were identified as bougracol A (1), 4, 7-dihydroxy-5-methoxy-8-methyl-6-formyl-flavane (2), 7-O-methylunonal (3), 5,7-dihydroxy-6,8-dimethyl-2-phenyl-4H-1-benzopyran-4-one (4), desmosflavone (5) and demethoxymatteucinol (6). Among them, compound 1, a new flavan-diols, was deduced to be 7-hydroxy-5-methoxy-8-methyl-6-formyl-flavan-3 4-diols, and compounds 2-6 were. firstly obtained from this plant. Anti-HIV assay suggests that compounds 1, 2, 5, 6 showed weak anti-HIV activities with EC50 values of 45.09, 48.73, 55.47 and 82.75 mu mol/L, and TI values of 1.41, 1.20, 7.15 and >8.51, respectively.
