Preparation of Stigmasterol: it is extracted from soybean oil. Firstly, the unsaponifiable in soybean oil is dealed by acetylation and bromination. Then the reactant is dissolved in mixed solvent of ether and acetic acid. Secondly, tetrabromide is separated and extracted. At last, product is obtained after debromination and saponification through Zinc and acetic acid.
