目的研究丝毛瑞香的化学成分。方法利用硅胶柱色谱、凝胶柱色谱进行分离,通过波谱解析和理化性质进行化合物结构鉴定。结果分离得到10个化合物,分别鉴定为oleodaphnal(Ⅰ)s、esquiterpene oxolactone(Ⅱ)、对羟基桂皮酸(Ⅲ)、对羟基桂皮酸正二十酯(Ⅳ)、对羟基桂皮酸正二十二酯(Ⅴ)、咖啡酸甲酯(Ⅵ)、咖啡酸正二十酯(Ⅶ)、β-谷甾醇(Ⅷ)、β-谷甾酮(Ⅸ)和胡萝卜苷(Ⅹ)。结论化合物Ⅱ为首次从该属植物中分离得到,其余均为首次从本植物中分离得到。
Objective To study the chemical constituents of Silybum marianum Methods The compounds were isolated by silica gel column chromatography and gel column chromatography. Their structures were elucidated by spectral analysis and physicochemical properties. Results Ten compounds were isolated and identified as oleodaphnal (Ⅰ) s, esquiterpene oxolactone (Ⅱ), p-hydroxycinnamic acid (Ⅲ), n-eicosanoyl p-hydroxycinnamic acid (Ⅴ), caffeic acid methyl ester (Ⅵ), caffeic acid n-eicosalate (Ⅶ), β-sitosterol (Ⅷ), β-sitosterone (Ⅸ) and daucosteride (Ⅹ). Conclusion Compound Ⅱ was isolated from this genus for the first time, and the rest was isolated from this plant for the first time.
