金线草化学成分研究

Studies on the Chemical Constituents of the Herb of Antenoron filiforme

目的:研究蓼科药用植物金线草的化学成分。方法:采用色谱分离技术进行分离纯化,通过波谱分析鉴定化合物结构。结果:从金线草的乙醇提取物中共分离鉴定了11个化合物,分别为:5-羟基-2-O-β-D-吡喃葡萄糖基-龙脑(Ⅰ)、腺苷(Ⅱ)、1-O-β-D-吡喃葡萄糖基-2-(9Δ-十六酰胺基)-3,4,12-三羟基正十八烷醇(Ⅲ)、鼠李黄素(Ⅳ)、3-O-β-D-吡喃半乳糖苷-槲皮素(Ⅴ)、3-O-β-D-吡喃半乳糖苷-鼠李黄素(Ⅵ)、3,7-二-O-α-L-吡喃鼠李糖基-山柰酚(Ⅶ)、豆甾醇(Ⅷ)、正二十九烷酸(Ⅸ)、胡萝卜苷(Ⅹ)、谷甾醇(Ⅺ)。结论:所有化合物均为首次从该植物中分离得到。

Objective：To study the chemical constituents of the herb of Antenoron filiforme.Methods：The constituents were separated by column chromatography and their structures were elucidated by spectral data analyses.Results：Eleven compounds were isolated from the ethanol extract of A.filiforme and identified as,bronane-5-hydroxy-2-O-β-D-glucopyranoside（Ⅰ）,adenosine（Ⅱ）,bonaroside（Ⅲ）,rhamnetin（Ⅳ）,hyperoside（Ⅴ）,rhamnetin-3-O-β-D-galactopyranoside（Ⅵ）,kaempferol-3,7-O-bis-α-L-rhamnopyranoside（Ⅶ）,stigmasterol（Ⅷ）,nonacosanoic acid（Ⅸ）,daucosterol（Ⅹ）,3β-sitosterol（Ⅺ）.Conclusion：All compounds are obtained from A.filiforme for the first time.
