目的:研究单麻叶千里光Senecio cannabifolius var.integrilifolius(Koidz.)Kitam.地上部分的化学成分,为阐明其有效成分提供科学依据。方法:采用silicagel、SephadexLH-20及RP18等柱层析色谱方法进行分离纯化,并根据理化性质和光谱数据鉴定其结构。结果:分离得到9个化合物,分别鉴定为:柳杉酚(1)、浙贝素(2)、消旋丁香脂素(3)、齐墩果烷(4)、1,4-苯二酚(5)、2,5-二羟基苯乙酸乙酯(6)、对羟基苯乙酰胺(7)、槲皮素(8)及金丝桃苷(9)。结论:化合物1和2为首次从该属植物中分离得到,化合物1～9均为首次从该植物中分离得到。
Objective: To study the chemical constituents of aerial parts of Senecio cannabifolius var.integrilifolius (Koidz.) Kitam, providing a scientific basis for clarifying the active ingredients. METHODS: Separation and purification were carried out by column chromatography, such as silicagel, Sephadex LH-20 and RP18. The structures of the compounds were identified by their physicochemical properties and spectral data. Results: Nine compounds were isolated and identified as: cedrylol (1), zebu (2), racemic melatonin (3), oleanane (4) (5), ethyl 2,5-dihydroxyphenylacetate (6), p-hydroxyphenylacetamide (7), quercetin (8) and hyperoside (9). Conclusion: Compounds 1 and 2 were isolated from this genus for the first time. Compounds 1 to 9 were isolated from this plant for the first time.
