摘　　要：Investigations on the chemical constituents from the ethanol extract of the agarwood originating from Aquilaria filaria led to the isolation of 26 compounds by column chromatography,including silica gel,Sephadex LH-20,and semi-preparative high-performance liquid chromatography.Their structures were determined to beβ-sitostenone(1),24α-ethyl-cholestan-3α-ol(2),ergosta-4,6,8(14),22-tetraene-3-one(3),gypsogenin(4),hederagenin(5),17αH-trisnorhopanone(6),lupeol(7),friedelin(8),(-)-episyringaresinol(9),(-)-syringaresinol(10),5-hydroxy-7,4′-dimethoxyflavone(11),5,4’-dihydroxy-7,3′-dimethoxyflavone(12),2′-hydroxy-4,3′,6′,4′′-tetramethoxy-p-terphenyl(13),scopularide A(14),4-(4-hydroxyphenyl)butan-2-one(15),zingerone(16),coniferaldehyde(17),scopoletin(18),acetovanillon(19),isovanillin(20),vanillin(21),p-hydroxybenzaldehyde(22),p-hydroxybenzoic acid(23),protocatechuic acid(24),vanillic acid(25)and 4,5-dihydroxy-3-methoxybenzoic acid(26)by using spectroscopic techniques.All compounds were isolated from agarwood of A.filaria for the first time,and this was also the first report about the isolation of compounds 2,4,6,7,9,10,13-15,17-20,22,24 and 26 from agarwood and Aquilaria plants.为研究丝沉香的化学成分,本研究采用硅胶、葡聚糖凝胶LH-20、半制备高效液相色谱等多种柱层析技术从丝沉香的乙醇提取物分离得到26个化合物,运用波谱学方法分别鉴定为β-谷甾酮(1)、24α-乙基-3α-胆甾醇(2)、麦角-4,6,8(14),22-四烯-3-酮(3)、丝石竹皂苷元(4)、常春藤皂苷元(5)、17αH-trisnorhopanone(6)、羽扇豆醇(7)、木栓酮(8)、(-)-表丁香树脂醇(9)、丁香树脂醇(10)、5-羟基-7,4′-二甲氧基黄酮(11)、5,4′-二羟基-7,3′-二甲氧基黄酮(12)、2′-羟基-4,3′,6′,4′′-四甲氧基对三联苯(13)、scopularide A(14)、覆盆子酮(15)、姜油酮(16)、松柏醛(17)、7-羟基-6-甲氧基香豆素(18)、乙酰香子兰酮(19)、异香草醛(20)、香草醛(21)、对羟基苯甲醛(22)、对羟基苯甲酸(23)、原儿茶酸(24)、香草酸(25)和没食子酸-3-甲基醚(26)。以上化合物均为首次从丝沉香中分离鉴定,化合物2,4,6,7,9,10,13-15,17-20,22,24和26为首次从沉香和其基源植物中报道。
