PURPOSE:To produce a plant growth promoter extremely useful in terms of industry, by extracting brassinolide from a deodorized distillate of edible vegetable oils as an industrial waste, separating and purifying. CONSTITUTION:A deodorized distillate, a bad-smell component removed in processes of squeezing oil from soybean oil, colza corn, etc., and purifying the oil, is saponified with an alkali and then extracted with an ether to give an unsaponified soybean oil. Brassinolide is separated from the unsaponified soybean oil by solvent fractionation through partition operation between solvents and column chromatography of silica gel and is used as a plant growth promoter.
