Chilli seed oil prepared by solvent extraction and blend oil prepared by oil decoction method, basic physicochemical properties, fatty acids, oil yield and oil the main constituents of comparative were studied. The blend oil prepared by solvent extraction and prepared by chili oil decoction method respectively, GC analysis was used, and the main components of the calculation of the relative percentage content was determined by extraction area normalization method. Results showed that fatty acids yield of solvent extraction and decoction method was 88.63%, 87.72%, respectively, and the main che...
