| The Meles meles oil, mink oil and raccoon dog oil were extracted from the subcutaneous fat of Meles meles, mink and raccoon respectively.The fatty acid compositions of Meles meles oil, mink oil and raccoon dog oil were analyzed by gas chromatography-mass spectrometry (GC-MS), and their antioxidant capacities in vitro were respectively tested by 1,1-diphenyl-2- picrylhydrazyl (DPPH) free radicals scavenging capacity.The pouring method was used to determine the antibacterial properties of the three oils against E. coli, Salmonella and Staphylococcus aureus.The results showed that the main fatty acid compositions of Meles meles oil, mink oil and raccoon dog oil were oleic acid, linoleic acid and palmitic acid, and their unsaturated fatty acids contents were 76.296%, 76.515% and 78.908%, respectively.The IC50 for scanvenging DPPH free radicals of Meles meles oil, mink oil, and raccoon dog oil were 0.315, 0.074 g/mL and 0.081 g/mL, respectively. That was, mink oil was slightly better than raccoon dog oil in the scanvenging DPPH free radicals, and was significantly better than Meles meles oil. Meles meles oil, mink oil, and raccoon dog oil had no antibacterial effects on E. coli, Salmonella, and Staphylococcus aureus. |
