摘要
从山竺(Garcinia mangostana)果壳中分离得到6个化合物,通过MS,1D NMR以及与文献对照鉴定它们为4个[口山]酮类化合物:α-rnangostin(1),β-mangostin(2),γ-mangostin(3),5,9-dihydroxy-8-methoxy-2,2-dimethyl-7-(3-methylbut-2-envl)-2H,6H-pyrano-[3,2-b]-xanthen-6-one(4),以及表儿茶素(epicatechin,5)和一个双苄类化合物egonol(6)。其中化合物5和化合物6为首次从该植物中分离得到。对化合物1~5进行抗HIV-1 RT活性筛选结果表明,化合物2和化合物5在浓度200μg/ml的条件下,其对HIV-1 RT抑制率分别为41.97%和47.72%;同一实验结果显示化合物1,3和4没有抑制HIV-1 RT作用。
From the fruit hulls of Garcinia mangostana, six known compounds were isolated and identified as α-mangostin (1), β-mangostin (2), γ-mangostin (3), 5, 9-dihydroxy-8-methoxy-2, 2-dimethyl-7-(3-methylbut-2-enyl)-2H, 6H-pyrano -[3, 2-b ]-xanthen-6-one (4), epicatechin (5) and egonol (6) based on spectral analysis and by comparison with literature data. Compound 5 and 6 were isolated form this plant for the first time. Meanwhile, In vitro bioassay screening, the results indicated that β-mangostin (2) and epicatechin (5) showed inhibitory activities on recombinant HIV-1 RT with inhibitory percentage of 41.97 and 47.72 at 200 μg/ml. Compounds 1, 3 and 4 showed no inhibitory activities at the same bioassay.
