Stigmasterol and its acetate were epoxdized by perbenzoic acid in dioxane, benzene, diethyl ether, acetone or chloroform. In dioxane or acetone, at 03°C, decomposition (or reaction with the solvent) of perbenzoic acid occured but the rate of epoxidation was slower than in chloroform. In benzene, the rate was slightly slower than in chloroform. In ether, at room temperature, decomposition (or reaction with solvent) of perbenzoic acid also occured but at 03°C, mainly 5, 6-bond out of the two double bonds was epoxidized under the condition of 4 moles perbenzoic acid per 1 mole sterol.
