三叶木通茎中的苯丙素类化学成分

Phenylpropanoids from the Stems of Akebia trifoliata

为了解三叶木通[Akebia trifoliata(Thunb.)Koidaz]的化学成分,从其茎的乙醇提取物中分离得到7个苯丙素类化合物。经过光谱分析,分别鉴定为osmanthuside E(1)、木通苯乙醇苷B(2)、2-(4-hydroxyphenyl)ethyl-(6-O-feruloyl)-β-D-glucopyranoside(3)、dunalianoside D(4)、dunalianoside C(5)、咖啡酸(6)、秦皮乙素(7)。除化合物6外,其他化合物均为首次从该植物中分离获得,化合物4和5为首次从木通属植物中分离得到。

In order to understand the chemical constituents of Akebia trifoliata, seven phenylpropanoid compounds were isolated from the ethanol extract of Akebia trifoliata stems. On the basis of spectral data, their structures were identified as osmanthuside E (1), calceolarioside B (2), 2-(4-hydroxyphenyl)ethyl-(6-O-feruloyl)-β-D-glucopyranoside (3), dunalianoside D (4), dunalianoside C (5), caffeic acid (6) and aesculetin (7). These compounds, except of compound 6, were isolated from the plant for the ifrst time, and compounds 4 and 5 were obtained from the genus Akebia for the ifrst time.
