枳实药材乙醇提取物的化学成分研究

摘要

目的:研究枳实药材乙醇提取物的化学成分.方法:采用硅胶柱、开放ODS柱、制备液相色谱、HW-40F凝胶柱、大孔树脂柱对枳实药材乙醇提取物进行分离纯化,根据理化性质和波谱(质谱、氢谱、碳谱)数据分析鉴定化合物结构.结果:从枳实药材乙醇提取物中分离得到8个化合物,分别鉴定为Rimboxo(1)、胸苷(2)、尿嘧啶(3)、环-(亮氨酸1-异亮氨酸2-丙氨酸3-苏氨酸4-甘氨酸5-苏氨酸6-苯丙氨酸7)(4)、环-(亮氨酸1-亮氨酸2-脯氨酸3-酪氨酸4-甘氨酸5-丝氨酸6-脯氨酸7)(5)、水合橙皮内酯-β-D-葡萄糖苷(6)、伞形花内酯(7)、里那醇苷(8).结论:化合物1、2、3、8为首次从柑橘属植物中分离得到,化合物4、5、6为首次从枳实药材中分离得到,该研究为枳实药材质量评价奠定了一定基础.%OBJECTIVE: To study the chemical constituents of ethanol extract from Cirtus aurantium. METHODS: The ethanol extract of C. aurantium was isolated and purified by silica gel column, open ODS column, preparation liquid chromatography, HW-40F gel column and macroporous resin column. The structure of compounds was analyzed and identified according to physicochemical properties and spectral data (mass spectrum, hydrogen spectrum, carbon spectrum). RESULTS: Eight compounds were isolated from ethanol extract of C. aurantium, i. e. Rimboxo (1), Thymidine (2), Uracil (3), Cyclo-(Leu1-Ile2-Ala3-Thr4-Gly5-Thr6-Phe7) (4), Cyclo- (Leu1-Leu2-Pro3-Tyr4-Gly5-Ser6-Pro7) (5), Meranzin hydrate-β-D-glucoside (6), Umbelliferone (7), Linaloyl glucoside (8). CONCLUSIONS: Compound 1, 2, 3, 8 are isolated from Citrus L. for the first time, compound 4, 5, 6 were isolated from C. aurantium for the first time. The study lays the foundation for quality evaluation of C. aurantium.
