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。
The chemical constituents of Solanum torvum (Solanum torvum), a Solanum Solanum torvum, were isolated by column chromatography and high performance liquid chromatography (HPLC). Six compounds were isolated from them. Their structures were characterized by spectral analysis as 2,3-trans-dihydro-2- (4-hydroxy-3-methoxyphenyl) -3 - [7-methoxybenzofuran-5-propenoic acid 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). Among them, compound 1 is a new lignan glycoside component.
