[Effect of an extract containing esterol on plasma cholesterol and oxidants].
16 patients with hypercholesterolemia were treated with an extract of alpha-alpha leaves (esterol) while on a low-fat, low-cholesterol diet. Esterol is believed to inhibit the absorption of cholesterol and bile acids and may interfere with the absorption of essential nutrients. As oxidative modification of lipoproteins is required for the process of atherosclerosis, plasma antioxidant vitamins were followed. After 4 months of treatment, plasma cholesterol decreased by 10% from 282 to 250 mg/dl (p < 0.001) and LDL cholesterol by 13%, from 203 to 177 mg/dl (p < 0.001). Plasma antioxidant vitamins E, A and beta-carotene were unchanged. Thus, esterol has a cholesterol-lowering effect but apparently does not lower fat-soluble, plasma antioxidant vitamins. Both cholesterol-lowering and plasma antioxidant vitamins are important for the primary prevention of coronary artery disease in hypercholesterolemia.
