Analysis on fatty acids of Cervi Cornu Pantotrichum with different processing methods by gas chromatography / 中草药

ABSTRACT

Objective: To study the differences and the trends of fatty acids content in different parts of Cervi Cornu Pantotrichum (CCP) with different processing methods. Methods: KOH-CH3OH esterification and n-hexane extraction were combined as the pretreatment method to obtain the fatty acid samples, and then the samples were analyzed by gas chromatography. Results: The fatty acids content in wax slices, powder slices, and bee slices of CCP without blood were 16.00, 10.32, and 5.51 g/kg. The fatty acids contents in wax slices, powder slices, and bee slices of CCP with blood were 14.81, 6.04, and 4.88 g/kg. The fatty acids contents in wax slices, powder slices, and bee slices of CCP with boiling processing were 9.06, 6.20, and 4.23 g/kg. The fatty acids contents in wax slices, powder slices, and bee slices of CCP with freeze-drying were 9.46, 7.54, and 6.23 g/kg. Conclusion: The contents of fatty acids in CCP with different processing methods are different. The content of fatty acids in CCP without blood is higher than that in CCP with bloods, and the content of fatty acids in CCP with boilding processing is lower than that in CCP with freeze-drying. The trend of different parts of antlers with the same processing method shows decreasing one by one from wax slices to bee slices. The main saturated fatty acids in the antlers are palmitic acid (C160) and stearic acid (C180). The mono unsaturated fatty acids are mainly oleic acid (C181, cis-9). The content of γ-linolenic acid (C183, cis-9, 12, 15), twenty C two acid (C202, cis-11, 14), and four arachidonic acid (C20 4, cis-5, 8, 11, 14) in polyunsaturated fatty acids are higher than others.
