丝毛瑞香化学成分分析

Analyses on Chemical Constituents of Daphe holosericea

摘要: 通过柱层析方法对丝毛瑞香的化学成分进行分离纯化，得到12个化合物。用波谱数据和理化常数进行化合物结构鉴定，分别鉴定为：β-谷甾醇 (1)、1-hexadecanol (2)、丁香醛 (3)、咖啡酸正二十脂 (4)、β-谷甾醇丁酸酯(5)、芹菜素 (6)、4-(ethoxy) benzoic acid (7)、(2R, 3S)-2-hydroxy-2,3-bis(4-hydroxy-3-methoxyben-zyl)-4-butanolide (8)、p-hydroxy-benzaldehyde (9)、p-anisic acid (10)、对羟基苯甲酸 (11)、2-hexylidene-3-methylsuccinic acid (12)。

Abstract: Column chromatography was applied to study the chemical constituents of Daphe holosericea, and 12 compounds were isolated from this plant species.The structures of the 12 compounds were identified as βsitosterol (1), 1hexadecanol (2), syringaldehyde (3), caffeic acid ndueicosanyl ester (4), βsitosteryl butyrate (5), apigenin (6), 4(ethoxy) benzoic acid (7), (2R, 3S)2hydroxy2,3bis(4hydroxy3methoxybenzyl)4butanolide (8), phydroxylbenzaldehyde (9), panisic acid (10), phydroxybenzoic acid (11), 2hexylidene3methylsuccinic acid (12) by the spectral analyses and the physicochemical properties. Compounds 2, 3, and 512 were isolated for the first time from this plant species.
