Study on fatty acid composition and assisting for lipid lowering of wild peony seed oil from Western Hunan

The fatty acid composition of peony seed oil from Western Hunan was testing by GC-MS method.The assist effect for lipid lowering was testing through the 50 human feeding trials.The result indicated that the compositions of peony seed oil from Western Hunan were: palmitic acid of 6.04%, stearic acid of 1.84%, oleic acid of 25.20%, linoleic acid of 28.65% and linolenic acid of 37.41%.The total concentration of polyunsaturated fatty acid reached to 91.26%.Peony seed oil from Western Hunan could lower the TC ( serum total cholesterol) , TG ( triglyceride) , LDL-C ( low density lipoprotein cholesterol) levels of human subjects obviously and the lower range were 13.20%, 35.98%, 10.72%, respectively, with statistically significant in difference, and the total effective rates could reach to 70.73%, 81.40%, 66.67%, respectively, but no effect on HDL-C ( high density lipoprotein cholesterol) levels, which indicated the peony seed oil had better assisting for lipid lowering.
