摘要
目的研究地骨皮Lycii Cortex(root bark of Lycium chinense)的化学成分。方法采用硅胶、Sephadex LH-20、ODS等多种色谱学方法分离纯化,根据理化性质和波谱数据进行结构鉴定。结果从地骨皮95%乙醇提取物的醋酸乙酯部位中分离得到12个化合物,分别鉴定为反式-N-对羟基香豆酰酪胺(1)、反式-N-阿魏酰酪胺(2)、二氢咖啡酰酪胺(3)、芹菜素(4)、阿魏酸(5)、对羟基香豆酸(6)、3-羟基-1-(4-羟基苯基)-丙基-1-酮(7)、3,4-二羟基苯丙酸(8)、3,4-二羟基苯丙酸甲酯(9)、对羟基苯甲酸(10)、4-甲氧基水杨酸(11)、烟酸(12)。结论化合物8和9为新的天然产物,化合物1、6、11及12为从该植物中首次分离得到。
Objective To study the chemical constituents from the root barks of Lycium chinense. Methods The chemical constituents of EtOAc fraction from 95% ethanol extract of L. chinense were isolated and purified by chromatography on silica gel, Sephadex LH-20, and ODS. Their chemical structures were identified on the basis of physicochemical properties and spectroscopic data. Results Twelve compounds were isolated and identified as N-trans-coumaroyltyramine(1), N-trans-feruloyltyramine(2), dihydro-N-caffeoyltyramine(3), apigenin(4), ferulic acid(5), p-hydroxycinnamic acid(6), 3-hydroxy-1-(4-hydroxyphenyl)-1-propanone(7), 3, 4-dihydroxybenzenepropionic acid(8), 3, 4-dihydroxybenzenepropionic acid methyl ester(9), p-hydroxy-benzoic acid(10), 4-methoxy salicylic acid(11), and nicotinic acid(12). Conclusion Compounds 8 and 9 are two new natural products, and compounds 1, 6, 11, and 12 are obtained from this plant for the first time.
