OPTIMAL EXTRACTION METHODS FOR THE TOCOCHROMANOL IN SOYBEAN

摘要

PURPOSE: An optimum extraction method of a tocochromanol component from beans is provided to obtain the high content of tocochromanol from the beans. CONSTITUTION: An extraction method of a tocochromanol component from beans comprises a step of extracting tocochromanol from the beans using an ethanol solvent distillation method. The beans are bean seeds or germinated beans. The bean seeds or germinated beans are crushed under the presence of liquid nitrogen. The bean seeds are extracted by using a mixed solution of 80-90 wt% of hexane and 10-20 wt% of ethyl acetate at 140-180°C through a Soxhlet method. The germinated beans are extracted by using an ethanol solution containing pyrogallol through a solvent extraction method. The germinated beans are germinated at a low temperature for 2-4 days.
