Abstract

The invention provides a method for extracting selenium cordyceps essence. The method is characterized by comprising the following extracting steps: (a) drying and processing selenium cordyceps; (b) crushing the dried and processed selenium cordyceps; (c) extracting the crushed selenium cordyceps in a regurgitation manner; (d) spray drying the selenium cordyceps which is extracted in the regurgitation manner; (e) vacuum packing the dried selenium cordyceps. According to the method for extracting the selenium cordyceps essence, a solvent auxiliary ultrasound two-step hot reflux extraction method is used, so that effective components in the selenium cordyceps are more sufficiently extracted, and the extraction rate of selenium reaches more than 90%; the solvent auxiliary ultrasound two-step hot reflux extraction method optimizes the extraction time, so that the extraction time is greatly shortened by more than 2 / 3 when compared with that of the traditional method; the extraction temperature is below 60 DEG C, so that the method has a protection effect on effective components in medicinal materials which are unstable when being heated and are easy to hydrolyze or oxidize, and the energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to a method for extracting selenium cordyceps essence. Background technique [0002] Cordyceps contains cordycepin, cordycepic acid, polysaccharides, more than 10 kinds of amino acids and various trace elements. Modern medical and nutritional studies have shown that Cordyceps can regulate the immune system and blood system, protect and prevent kidney, liver, and heart damage, and have anti-aging, anti-stress, and anti-tumor effects. However, due to strict parasitism and special growth geographical environment restrictions, drug sources are in short supply and expensive, which is far from meeting the market demand. Selenium is an essential trace element for the human body. Modern medical research shows that selenium deficiency is related to the occurrence of more than 40 diseases such as Keshan disease, Kaschin-Beck disease, cardiovascular and cerebrovascular diseases, and cancer. Selenium supplementation can effectively reduce t...
