大果榕茎的化学成分

摘要

运用硅胶柱色谱和Sephadex LH-20柱色谱,以及制备薄层色谱等方法从大果榕茎的95％乙醇提取物中分离得到11个化合物,通过理化性质和波谱数据鉴定为:染料木黄酮(1),wighteone (2),5,7,4’,trihydroxy-6-(2-hydroxy-3-methyl-3-butenyl) isoflavone(3),5,7,4’-trhydroxy-3’-(2-hydroxy-3-methyl-3-butenyl) isoflavone(4),alpinumisoflavone(5),derrone(6),(3R)-5-formylmellein(7),3β-(1-Hydroxyethyl)-7-hydroxy-1-isobenzofuranone(8),反式对羟基肉桂酸乙酯(9),β-谷甾醇(10),β-胡萝卜苷(11).化合物4,7,8,9为首次从该属植物中分离得到,化合物1-10为首次从该植物中分离得到.%Eleven compounds were isolated from 95％ ethanol extracts of the stems of Ficus auriculata Lour.The constituents were isolated and purified by silica gel column chromatography,Sephadex LH-20 and preparative TLC.Their structures were identified on the physiochemical characteristics and basis of spectral data.Their structures were identified as genistein (1),wighteone (2),5,7,4',trihydroxy-6-(2-hydroxy-3-methyl-3-butenyl) isoflavone (3),5,7,4'-trihydroxy-3'-(2-hydroxy-3-methyl-3-butenyl) isoflavone (4),alpinumisoflavone (5),derrone (6),(3R)-5-formylmellein (7),3β-(1β-hydroxyethyl)-7-hydroxy-1-isobenzofuranone (8),trans-p-hydroxycinnamic acid ethyl ester (9),β-sitosteral (10),andβ-daucosterol (11).Compounds 4,7,8,9 were reported from the genus Ficus for the first time.Compounds 1-10 were isolated from this plant material for the first time.
