A process for the preparation of sterols and tocopherols from plant materials like soybean oil deodorizer distillate is disclosed. The process comprising steps of aqueous saponification, followed by esterification and crystallization of crude sterol crystals and separation of mother liquor containing tocopherols, and finally recrystallization of said crude sterol crystals to the final sterol preparations of higher purity and yield. The mother liquor so obtained is subjected to molecular distillation, following by solvent extraction and resin purification to get tocopherol preparations of higher purity and yield for use in pharmaceutical, neutraceutical and cosmetic products.
