目的研究楮头红(Sarcopyramis nepdensis)的化学成分。方法采用硅胶、大孔树脂、Sephadex LH-20和ODS等色谱手段进行化学成分的分离纯化,依据理化性质、波谱数据和相关文献进行结构鉴定。结果分离鉴定了11个化合物,分别为丁香树脂酚(syringaresinol,1),羟基苯甲酸甲酯(methyl 4-hydroxybenzoate,2),3-甲氧基-4-羟基苯甲醛(3-methoxy-4-hydroxybenzal-dehyde,3),胆甾烯基亚油酸酯(cholestery 9,12-octadecadienoate,4),胆甾醇基十七酸酯(cholesteryl hepadecanoate,5),cholesterytrans-cinnamate(6),arjunic acid(7),咖啡酸(3,4-dihydroxycinnamic acid,8),β-谷甾醇(β-sitosterol,9),β-胡萝卜苷(daucosterol,10),aralidioside(11)。结论除化合物9和10外,其余所有化合物均为首次从楮头红中分离得到。
Objective To study the chemical constituents of Sarcopyramis nepdensis. Methods Silica gel, macroporous resin, Sephadex LH-20 and ODS were used to separate and purify the chemical constituents. The structures were elucidated on the basis of physico-chemical properties, spectral data and related literature. Results Eleven compounds were isolated and identified as syringaresinol (1), methyl 4-hydroxybenzoate (2), 3-methoxy-4 -hydroxybenzal-dehyde, 3) cholestery 9,12-octadecadienoate (4), cholesteryl hepadecanoate (5), cholesterytrans-cinnamate (7), 3,4-dihydroxycinnamic acid (8), β-sitosterol (9), β-daucosterol (10) and aralidioside (11). Conclusion All of the compounds except for compounds 9 and 10 were isolated for the first time.
