A phytochemical study of Ficus thonningii has led to the isolation of two previously unreported compounds, thonningiiflavanonol A and thonningiiflavanonol B together with 16 known compounds: shuterin, naringenin, syringic acid, p-hydroxybenzoic acid, genistein, 5,7,3',4',5'-pentahydroxyflavanone, luteolin, methylparaben, aromadendrin, garbanzol, dihydroquercetin, 5,7,3'-trihydroxyflavanone, β-sitosterol, sitosterolglucoside, lupeol acetate, and taraxerol. Their structures were elucidated on the basis of spectroscopic data. The new compounds and extracts displayed potent antioxidant activity.
对托宁榕的植物化学研究已导致分离出两种先前未报道的化合物，即托宁黄酮醇A和托宁黄酮醇B，以及16种已知化合物：舒特林、柚皮素、丁香酸、对羟基苯甲酸、染料木素、5,7,3',4',5'-五羟基黄酮、木犀草素、对羟基苯甲酸甲酯、香豆素、加尔班醇、二氢槲皮素、5,7,3'-三羟基黄酮、β-谷甾醇、谷甾醇葡萄糖苷、乙酸羽扇豆醇酯和蒲公英赛醇。根据光谱数据阐明了它们的结构。新化合物和提取物表现出强大的抗氧化活性。
