Problems solved by technology
Melatonin has a very good therapeutic effect, especially for people with jet lag and sleep disorders, and can help restore normal sleep rhythms. The application number is 201610845424.7, a Chinese invention patent for a melatonin separation process. When extracting crushed walnuts directly, it is easy to cause waste, and after the extraction, impurities are filtered out. There are many impurities, which will easily affect the extraction effect. Therefore, we propose a method for extracting melatonin from the melatonin crystal mother liquor. Elemental methods are used to solve the above problems

The invention discloses a method for extracting melatonin from melatonin crystallization mother liquor. The method comprises the following steps of: 1, freezing a pineal body of an animal; 2, crushing the frozen pineal body in the step 1; 3, adding hot water into the crushed pineal body in the step 2, and carrying out centrifugal standing by using a centrifugal machine; 4, taking supernate of the centrifugate in the step 3; 5, filtering the supernate obtained in the step 4 to remove redundant impurities; 6, adding propylene glycol into the supernate filtered in the step 5, and extracting; and 7, heating the extract liquor in the step 6 to evaporate propylene glycol in the extract liquor and separate out melatonin crystals in the extract liquor. According to the invention, hot water is added into the crushed pineal body, so that the separation of melatonin is facilitated, and unnecessary waste is reduced.
Description
technical field [0001] The invention relates to the technical field of melatonin extraction, in particular to a method for extracting melatonin from melatonin crystallization mother liquor. Background technique [0002] Melatonin is a substance secreted by the pineal gland of the human brain, which plays a very important role in maintaining the normal circadian rhythm and sleep rhythm of the human body. If there is a disorder of melatonin secretion, it may lead to the reversal of people's sleep time, poor sleep quality, and insomnia. Melatonin has a very good therapeutic effect, especially for people with jet lag and sleep disorders, and can help restore normal sleep rhythms. The application number is 201610845424.7, a Chinese invention patent for a melatonin separation process. When extracting crushed walnuts directly, it is easy to cause waste, and after the extraction, impurities are filtered out. There are many impurities, which will easily affect the extraction effect....
