海南黄灯笼辣椒不同提取物化学成分GC-MS分析

目的:研究海南黄灯笼辣椒不同提取物中的化学成分,确定不同类型化学成分的合适提取溶剂.方法:海南黄灯笼辣椒分别用石油醚、乙酸乙酯和95％乙醇提取,提取物经GC-MS分析,比较不同提取物中所含化学成分的差异.结果:海南黄灯笼辣椒石油醚、乙酸乙酯和95％乙醇提取物中主要包含脂肪酸类、酰胺类(辣椒素和二氢辣椒素)、烃类、甾醇类和维生素类等几大类化合物.其中脂肪酸的含量在3种提取物中分别为63.40％,60.66％,16.16％,酰胺类(辣椒素和二氢辣椒素)为16.82％,27.64％,42.05％.结论:提取海南黄灯笼辣椒中的脂肪酸类以及一些小极性的烃类化合物宜用石油醚,提取酰胺类宜用选用95％乙醇.

Studies on Chemical Constituents of Different Extracts from Capsicum chinense by GC-MS

Objective: To study the chemical constituents extracted from Capsicum chinense with different solvents and find out the appropriate solvent which was suitable for the extraction of different types of chemical constituents. Method: C. chinense was extracted with petroleum ether, ethyl acetate and 95%ethanol respectively and then the extracts were analyzed by GC-MS. The varieties and content of the chemical constituents in different extracts were compared. Result: The petroleum ether, ethyl acetate and ethanol extracts from C. chinense mainly include fatty acids, acid amides (capsaicin and dihydrocapsaicin), hydrocarbon, sterols and vitamins. The content of fatty acids in three extracts was 63.40%, 60.66%, 16.16%, respectively, and the acid amides were 16.82%, 27.64%, 42.05%, respectively. Conclusion: The appropriate solvent of extracting the fatty acids and a few of hydrocarbons from C. chinense was petroleum ether, as for the extraction of the acid amides, 95% ethanol was more suitable.
