摘 要: 目的研究桑Morus alba L.枝的化学成分。方法桑枝60%乙醇提取液采用ODS、Sephadex LH-20、半制备柱进行分离纯化,根据理化性质及波谱数据鉴定所得化合物的结构。结果从中分离得到10个化合物,分别鉴定为4'-O-β-D-吡喃葡萄糖基-2'-羟基大花藜芦酚3-(6-O-β-D-吡喃葡萄糖基-β-D-吡喃葡萄糖苷)(1)、3-O-β-D-吡喃葡萄糖基-2'-羟基大花藜芦酚4'-(6-O-β-D-吡喃葡萄糖基-β-D-吡喃葡萄糖苷)(2)、桑皮苷A(3)、桑皮苷E(4)、桑皮苷F(5)、反式氧化白藜芦醇-4-O-β-D-吡喃葡萄糖苷(6)、反式氧化白藜芦醇-3-O-β-D-吡喃葡萄糖苷(7)、顺式桑皮苷A(8)、3,4-二甲氧基苯基β-D-呋喃芹糖基-(1→6)-β-D-吡喃葡萄糖苷(9)、kelampayoside A(10)。结论化合物9、10为首次从桑属植物中分离得到,化合物1、2、4~7为首次从该植物中分离得到。 AIM To study the chemical constituents from the twigs of Morus alba L.. METHODS The60% ethanol extract from M. alba twigs was isolated and purified by ODS,sephadax LH-20 and semi-preparative column,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Ten compounds were isolated and identified as 4'-O-β-D-glucopyranosyl-2'-hydroxyresveratrol 3-( 6-O-β-D-glucopyanosyl-β-D-glucopyranoside)( 1),3-O-β-D-glucopyranosyl-2'-hydroxyresveratrol 4'-( 6-O-β-Dglucopyanosyl-β-D-glucopyranoside)( 2),mulberroside A( 3),mulberroside E( 4),mulberroside F( 5),transoxyresveratrol-4'-O-β-D-glucopyranoside( 6),trans-oxyresveratrol 3-O-β-D-glucopyranoside( 7),cis-mulberroside A( 8),3,4-dimethoxyphenyl β-D-apiofuranosyl-( 1 →6)-β-D-glucopyranoside( 9),kelampayoside A( 10).CONCLUSION Compounds 9 and 10 are isolated from genus Morus for the first time,compounds 1,2,4-7 are first isolated from this plant.
