Application

β-Sitosterol was used to supplement diet of mice to study its effect on body mass accumulation.

Biochem/physiol Actions

β-Sitosterol is a plant sterol that has hypocholesterolemic activity.[1] Only 5% of β-Sitosterol is absorbed by humans. It is hypothesized that the cholesterol-lowering activity is by competing cholesterol for uptake by the cells or by interfering with the esterification of cholesterol.[2] β-Sitosterol is reported to reduce the incidence of colon tumors.[3]

The hypocholesterolemic activity of beta-sitosterol and its hydrogenated product, beta-sitostanol (dihydrositosterol or stigmastanol) has been compared in young male rats. When cholesterol was included in the diet, sitostanol consistently exhibited significantly greater hypocholesterolemic activity than sitosterol. There were no apparent
