水茄果实中的一个新木脂素苷

A new neolignan from fruit of Solanum torvum

应用柱色谱及高效液相色谱分离技术对茄科茄属植物水茄Solanum torvum果实进行化学成分研究,从中分离得到6个化合物。通过波谱分析技术分别鉴定为2,3-(trans)-dihydro-2-(4-hydroxy-3-methoxyphenyl)-3-[(β-D-glucopyranosyloxy)methyl]-7-methoxybenzofuran-5-propenoic acid(1),torvoside A(2),torvoside C(3),torvoside H(4),solanolactoside A(5),(25S)-6α-hydroxy-5α-spirostan-3-one-6-O-[α-L-rhamnopyranosyl-(1→3)-β-D-quinovopyranoside](6)。其中化合物1为新的木脂素苷类成分。

One new neolignan identified as 2,3-（ trans）-dihydro-2-（ 4-hydroxy-3-methoxyphenyl）-3-[（ β-D-glucopyranosyloxy） methyl]-7-methoxybenzofuran-5-propenoic acid（ 1） and five known steroidal glycosides namely torvoside A（ 2）,torvoside C（ 3）,torvoside H（ 4）,solanolactoside A（ 5）,（ 25S）-6α-hydroxy-5α-spirostan-3-one-6-O-[α-L-rhamnopyranosyl-（ 1 →3）-β-D-quinovopyranoside]（ 6） were isolated from the fruits of Solanum torvum. Their structures were elucidated on the basis of 1D,2D NMR and MS spectroscopic analysis.
