楮头红化学成分研究

Studies on Chemical Constituents of Sarcopyramis nepdensis

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 chemical constituents of Sarcopyramis nepdensis.METHODS The compounds were isolated by means of column chromatography on sinica gel,DIAION HP20,Sephadex LH-20 and ODS.Their structures were elucidated by physicochemical properties and spectra.RESULTS Eleven compounds were obtained and identified as syringaresinol（1）,methyl 4-hydroxybenzoate（2）,3-methoxy-4-hydroxybenzaldehyde（3）,cholestery 9,12-octadecadienoate（4）,cholesteryl hepadecanoate（5）,cholestery trans-cinnamate（6）,arjunic acid（7）,3,4-dihydroxycinnamic acid（8）,β-sitosterol（9）,daucosterol（10） and aralidioside（11）.CONCLUSION Compound 1,2,3,4,5,6,7,8 and 11 were isolated from the plant for the first time.
