A METHOD FOR PRODUCING POLICOSANOL FROM GREEN TEA LEAVES AND ITS PRODUCT

摘要

The present invention relates to a method for producing policosanol from green tea leaves and an extract thereof. The policosanol and the extract thereof can be used for health supplement food that prevents vascular diseases such as cerebral hemorrhage, cerebral infarction, stroke, vascular dementia, angina, myocardial infarction, cold hands, cold feet, numbness of limbs, and impotence which frequently occur to modern people, and enhances stamina and muscular endurance. The method includes the steps of: grinding dried green tea leaves; mixing oil obtained by a supercritical extraction using a solvent and a subsidiary solvent, with an aqueous solution containing ethanol, sodium hydroxide or potassium hydroxide, and water; agitating and heating the mixed aqueous solution at 60C for 90 minutes; performing a fraction process on the mixed aqueous solution after cooling the mixed aqueous solution at 0-20C; separating ethanol by centrifuging a remaining solution; and concentrating and drying the solution obtained in the earlier step.
