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

Abstract:

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.
