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'-trihydroxy-3'-(2-hydroxy-3-methyl-3-butenyl)isoflavone(4),alpin-umisoflavone(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）,and β-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.
