摘要
采用气相色谱法分析湘西野生牡丹籽油的脂肪酸组成,并通过50例人体试食实验探讨其辅助降血脂作用。结果表明,湘西野生牡丹籽油主要由棕榈酸6.04%、硬脂酸1.81%、油酸25.20%、亚油酸28.65%、亚麻酸37.41%组成,不饱和脂肪酸高达91.26%;湘西野生牡丹籽油可显著降低受试者的胆固醇(TC,Serum Total Cholesterol)、甘油三酯(TG,Triacylglyceride)、低密度脂蛋白胆固醇(LDL-C,Low Density Lipoprotein Cholesterol)水平,降幅分别为13.20%、35.98%、10.72%,差异具有统计学意义(p<0.05),总有效率分别可达70.73%、81.40%、66.67%,而对高密度脂蛋白胆固醇(HDL-C,High Density Lipoprotein Cholesterol)水平无影响,表明牡丹籽油具有较好的辅助降血脂功效。
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.
