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.
