The effect of a capsulated palm-oil-vitamin E concentrate (palmvitee) on human serum and lipoprotein lipids was assessed. Each palmvitee capsule contains approximately 18, approximately 42, and approximately 240 mg of tocopherols, tocotrienols, and palm olein, respectively. All volunteers took one palmvitee capsule per day for 30 consecutive days. Overnight fasting blood was taken from each volunteer before and after the experiment. Serum lipids and lipoproteins were analyzed by using the enzymatic CHOD-PAP method. Our results showed that palmvitee lowered both serum total cholesterol (TC) and low-density-lipoprotein cholesterol (LDL-C) concentrations in all the volunteers. The magnitude of reduction of serum TC ranged from 5.0% to 35.9% whereas the reduction of LDL-C values ranged from 0.9% to 37.0% when compared with their respective starting values. The effect of palmvitee on triglycerides (TGs) and HDL-C was not consistent. Our results show that the palmvitee has a hypocholesterolemic effect.
评估了一种胶囊装的棕榈油维生素E浓缩物（棕榈维他E）对人体血清和脂蛋白脂质的影响。每粒棕榈维他E胶囊分别含有约18毫克、约42毫克和约240毫克的生育酚、生育三烯酚和棕榈油精。所有志愿者连续30天每天服用一粒棕榈维他E胶囊。在实验前后从每位志愿者采集空腹过夜血样。采用酶法CHOD-PAP法分析血清脂质和脂蛋白。我们的结果表明，棕榈维他E降低了所有志愿者的血清总胆固醇（TC）和低密度脂蛋白胆固醇（LDL-C）浓度。与各自的起始值相比，血清TC的降低幅度为5.0%至35.9%，而LDL-C值的降低幅度为0.9%至37.0%。棕榈维他E对甘油三酯（TGs）和高密度脂蛋白胆固醇（HDL-C）的影响并不一致。我们的结果表明，棕榈维他E具有降胆固醇作用。
