Stigmastanol (sitostanol) is a phytosterol found in a variety of plant sources. Similar to sterol esters and stanol esters, stigmastanol inhibits the absorption of cholesterol from the diet. [2] [3] [4] Animal studies suggest that it also inhibits biosynthesis of cholesterol in the liver. [2] [ verification needed ]
Stigmastanol is the product of the reduction of β-sitosterol [5] and the hydrogenation of stigmasterol. [6]
