畲药半边风化学成分研究

Study on the Chemical Constituents of the Roots of Dendropanax chevalieri

目的:研究畲药半边风的化学成分。方法:利用硅胶、Sephadex LH-20、RP-18柱层析法分离纯化半边风的化学成分,并根据波谱数据及理化性质鉴定其结构。结果:分离了8个化合物,分别鉴定为:棕榈酸(1)、邻苯二甲酸二丁酯(2)、β-谷甾醇(3)、松柏醛(4)、东莨菪素(5)、β-hydroxypropiovanillon(6)、右旋松脂素(7)、右旋丁香树脂酚(8)。结论:除化合物3外,均为首次从该属植物中分离得到。

Objective ： To study the chemical constituents of the roots of Dendropanax chevalieri. Methods ： The constituents were isolated by column chromatography with silica gel, Sephadex LH-20 gel and RP-18. Their structures were elucidated by analysis of spectral data and physicochemical properties. Results ： Eight compounds were isolated and identified as palmitic acid （ 1 ）, dibutyl- phthalate （ 2 ）,β-sitosterol （ 3 ）, coniferaldehyde （4）, scopoletin （ 5 ）,β-hydroxypropiovanillone （ 6 ）, （ ＋ ） -pinoresinol （7）, （ ＋ ） -syrin- garesinol（8）. Conclusion： Compounds 1 -2, 4 -8 are obtained from this genus for the first time.
