NOVELTY - Isolation of sterols and tocopherols from a deodorizer distillate of oil, comprises e.g.: (a) providing distillate comprising free and bound sterols and tocopherols; (b) saponifying distillate by contacting it with inorganic base in water at elevated temperature and pressure for specific time to form a soap composition; (c) acidulating soap composition with an inorganic acid at an elevated temperature for a specific time to form an acidified composition; and (d) separating aqueous mass from acidified composition by layer separation leading to formation of organic composition.    USE - The process is useful for isolating sterols and tocopherols from a deodorizer distillate of oil, where sterols or tocopherols are useful in a pharmaceutical, nutraceuticals and cosmetic product, and the deodorizer distillate is at least one of soybean oil, sunflower oil, rice bran oil, coconut oil and palm kernel oil (claimed).    ADVANTAGE - The process provides sterols and tocopherols from plant materials using green, non-toxic and economic methods with higher quality/purity of final preparations, and utilizes fewer amounts of organic solvents over known methods, thus providing economic value and improved control over the waste by-product treatment.    DETAILED DESCRIPTION - Isolation of sterols and tocopherols from a deodorizer distillate of oil, comprises: (a) providing a deodorizer distillate comprising free and bound sterols and tocopherols; (b) saponifying the deodorizer distillate by contacting it with an inorganic base in water at an elevated temperature and pressure for a specific time period leading to formation of a soap composition; (c) acidulating the soap composition with an inorganic acid at an elevated temperature for a specific time period leading to formation of an acidified composition; (d) separating aqueous mass from the acidified composition by layer separation leading to formation of an organic composition; (e) drying the organic composition by evaporation; (f) esterifying the dried organic composition with an alcohol in the presence of an acid catalyst and allowing formation of crude sterol crystals in remaining liquid reaction mass; (g) recovering the crude sterol crystals from the reaction mass leading to formation of a mother liquor; (h) purifying the crude sterol crystals by recrystallization; (i) subjecting the mother liquor to a molecular distillation to get a first crude tocopherol composition; (j) purifying the first crude tocopherol composition with solvent extraction to get a second crude tocopherol composition; and (k) subjecting the second crude tocopherol composition to a resin purification to get a final tocopherol composition. INDEPENDENT CLAIMS are also included for:    (1) a sterol composition comprising campesterol, stigmasterol and beta -sitosterol;    (2) a tocopherol composition comprising alpha , beta , gamma and delta derivatives of tocopherol;    (3) a sterol derivative prepared from sterols obtained in the above process; and    (4) a tocopherol derivative prepared from tocopherols obtained in the above.
