目的:研究桑科柘属植物构棘根的化学成分。方法:采用硅胶柱色谱、凝胶柱色谱、重结晶等方法进行分离纯化,根据理化性质及波谱数据对化合物进行结构鉴定。结果:从构棘根70%乙醇提取物中分离得到13个化合物,分别鉴定为:β-谷甾醇(1)、butyrospermol(2)、butyrospermol acetate(3)、右旋丁香树脂(4)、1,3,6-三羟基-7-甲氧基呫吨酮(5)、1,3,6,7-四羟基-8-异戊烯基呫吨酮(6)、山柰酚(7)、二氢山柰酚(8)、伞形花内酯(9)、对羟基苄基乙基醚(10)、2,4-二羟基苯甲醛(11)、对羟基苯甲醛(12)、香草醛(13)。结论:其中,化合物2~6、10~13为首次从该植物中分离得到。
Objective: To study the chemical constituents of spinous roots of Sarcocarpus. Methods: The compounds were separated and purified by silica gel column chromatography, gel column chromatography and recrystallization. The structures of the compounds were identified by their physical and chemical properties and spectral data. Results: Thirteen compounds were isolated from 70% ethanolic extracts of Echinacea purpurea and identified as β-sitosterol (1), butyrospermol (2), butyrospermol acetate (3), dextrose , 3,6-trihydroxy-7-methoxyxanthone (5), 1,3,6,7-tetrahydroxy-8-isopentenylxanthone (6), kaempferol (8), umbelliferone (9), p-hydroxybenzylethyl ether (10), 2,4-dihydroxybenzaldehyde (11), p-hydroxybenzaldehyde Vanillin (13). Conclusion: Among them, compounds 2 ~ 6 and 10 ~ 13 were isolated from this plant for the first time.
