| 中文摘要: |
| 目的:利用制备型高效液相色谱(PHPLC)研究草乌叶生物碱的分离纯化工艺为目的。方法:利用苯提取法得到草乌叶苯提取物。利用PHPLC将草乌叶苯提取物进行初步分离,分离产物用薄层色谱和分析型液相色谱分析,以确定目标峰。再次用PHPLC对目标峰进行分离和纯化,对所得各峰进行收集,薄层色谱和分析型液相色谱分析分离产物,验证分离效果。结果:草乌叶苯提取物经PHPLC初步分离后得到峰1~峰12。经薄层色谱和分析型液相色谱分析得知峰5~峰10含有大量生物碱。选择峰5作为研究对象,进一步使用PHPLC进行分离纯化,得到峰5-1~峰5-12等12个峰。薄层色谱和分析型液相色谱分析结果证明,峰5-4基本包含了峰5内的生物碱,为目标分离产物。结论:PHPLC初步分离和二次分离建立的色谱条件,可为草乌叶生物碱的大量精制提供依据。 |
| English Summary: |
| To study the alkaloids separation and purification method from leaves of kusnezoff monkshood root using Preparative High Performance Liquid Chromatography(PHPLC).Methods:benzene extraction method was used to obtain benzene extract from leaves of kusnezoff monkshood root.PHPLC was used to separate ingredients of benzene extract from leaves of kusnezoff monkshood root.Thin layer chromatography(TLC)and High Performance Liquid Chromatography(HPLC)were used to analyze the separated ingredients and determine the target peak.PHPLC was used to purify the target peak,the peaks were collected,the separated products were analyzed by TCL and HPLC to verify the separation effect.Results:A total of 12 Peaks were collected using PHPLC separation,designated as Peak 1~Peak 12.TLC and HPLC analysis showed that Peak 5~Peak 10 were enriched in alkaloids.Peak 5 was selected as an example to receive further PHPLC separation.A total of 12 peaks were seen,defined as Peaks 5-1~Peak 5-12.TLC and HPLC illustrated that Peak 5-4 contained most of alkaloids in Peak 5,which was the target separation product.Conclusion:Chromatographic conditions established by PHPLC primary separation and secondary separation can provide basis for the large-scale extraction of alkaloids from leaves of kusnezoff monkshood root. |
