The effect of β-sitosterol on the metabolism of cholesterol and lipids in rats on a diet low in fat

Abstract
Intraperitoneal injection of [beta]- sitosterol into rats fed on a low-fat cholesterol-free diet led to decreased concentrations of cholesterol and lipid in the tissues, increased incorporation of C14 into cholesterol, fatty acids and expired CO2 and decreased fecal excretion of sterols. There were no major changes in fatty acid composition of the lipids.
