摘要
目的研究茄科植物水茄Solanum torvum的化学成分。方法应用溶剂萃取及柱色谱方法分离水茄的化学成分,通过波谱技术鉴定化合物的结构。结果从水茄地上全草中分离得到11个化合物,其中有4个酰胺类、4个甾体皂苷类、2个黄酮类、1个有机酸类成分,分别鉴定为N-反式阿魏酸酪酰胺(1)、N-反式-对-香豆酰基酪胺(2)、3-(4-羟基苯基)-N-[2-(4-羟基苯基)-2-甲氧基乙基]丙烯酰胺(3)、N-反式-对-香豆酰基章鱼胺(4)、山柰酚(5)、槲皮素(6)、反式咖啡酸(7)、(25S)-6α-羟基-5α-螺甾烷-3-酮-6-O-(β-D-吡喃鸡纳糖苷)(8)、(25S)-6α-羟基-5α-螺甾烷-3-酮-6-O-[α-L-吡喃鼠李糖基-(1→3)-β-D-吡喃鸡纳糖苷](9)、(25S)-螺甾烷-5-烯-3β-醇-3-O-[β-D-吡喃葡萄糖基-(1→6)-O-β-D-吡喃葡萄糖苷](10)、(25S)-5α-螺甾烷-3β-醇-6α-O-[β-D-吡喃木糖基-(1→3)-β-D-吡喃鸡纳糖苷](11)。结论化合物3为新的天然产物,化合物1~7为首次从该植物中分得。
Objective To study the chemical constituents of Solanum torvum.Methods Column chromatography was used to isolate and purify the constituents,whose structures were identified on the basis of spectral data analyses.Results Eleven compounds were isolated and identified as N-trans-feruloyl tyramine(1),N-trans-P-coumaroyl tyramine(2),3-(4-hydroxyphenyl)-N-[2-(4-hydroxyphenyl)-2-methoxyethyl]-acrylamide(3),N-trans-P-coumaroyl octopamine(4),kaempferol(5),quercetin(6),trans-caffeic acid(7),solagenin 6-O-(β-D-quinovopyranoside)(8),(25S)-6α-hydroxy-5α-spirostan-3-one-6-O-[α-L-rhamnopyranosyl-(1→3)-β-D-quinovopyranoside](9),torvosides M(10),and 6α-O-[β-D-xylopyranosyl-(1→3)-β-D-quinovopyranosyl]-(25S)-5α-spirostan-3β-ol(11).Conclusion Compound 3 is firstly reported as a new natural product.Compounds 1—7 are isolated from S.torvum for the first time.
