Description

Cordycepin compound preparation, preparation method thereof and application thereof in preparation of sports fatigue improving products
Technical Field
The invention belongs to the technical field of natural medicines, and particularly relates to a cordycepin compound preparation, a preparation method thereof and application thereof in preparation of products for improving sports fatigue.
Background
Fatigue refers to the phenomenon in which the body is unable to maintain its function at a specific level and/or to maintain a predetermined intensity of movement during its physiology. If the fatigue cannot be eliminated in time after the fatigue is generated, the fatigue can be further developed into 'overstrain', so that endocrine disturbance, immunity decline and even organic lesions occur in the organism. Thus, fatigue has become a major factor in today's society threatening the health of humans. There are some strategies for relieving fatigue such as dietary supplements like taurine, creatine, l-carnitine, ginseng, rhodiola rosea, etc. However, its application is limited due to poor relief effect, large side effects, high cost, and the like. Therefore, it is essential to find more effective drug candidates with fewer side effects to alleviate fatigue.
Cordyceps militaris is a rare traditional Chinese medicine fungus containing bioactive substances such as cordycepin, mannitol, polysaccharide wheat, and cholesterol, and has been widely used in China for treating various diseases in circulatory system, immunity, respiration and glandular system, preventing aging, etc. The study shows that the cordycepin content of the cordyceps militaris is obviously higher than that of other fungi known at present, for the same cordyceps militaris, the cordycepin content of the fruiting body is obviously higher than that of hyphae. Cordycepin is also called 3-deoxyadenosine, is a natural product obtained by separating Cordyceps militaris, and has a structure very similar to adenosine, so that cordycepin is considered as a very effective bioactive component, and modern pharmacological research has shown that the cordycepin has wide physiological function regulating effects of immune system, nervous system, motor system, endocrine system and the like. The past researches show that the cordyceps militaris has the effect of relieving fatigue, can improve the secretion composition of neurotransmitters in sports fatigue mice, and the active ingredient cordycepin in the cordyceps militaris has obvious anti-fatigue effect, and the mechanism of the cordycepin is possibly related to energy consumption, metabolic processes, oxidative stress damage alleviation and neurotransmitter concentration change.
Ginsenoside is the main active ingredient of ginseng, pseudo-ginseng and American ginseng, is also the main ingredient of ginseng extract, has extremely strong pharmacological activity, and the content is an important evaluation index of the intrinsic quality of ginseng. Modern pharmacological research shows that ginsenoside can up regulate the transcription of neurotrophic factor mRNA by promoting the expression of hippocampal nerve growth factor and brain-derived neurotrophic factor mRNA in hippocampus, promote the repair of rat nerve injury, and relieve central fatigue caused by postoperative fatigue syndrome through nerve tissue regeneration and repair.
Maca is a Lepidium genus of Brassicaceae, belongs to annual or biennial herbaceous plants, and is produced in mountain areas with high altitude and severe ecological environment in south America. Maca is originally used as food by Peruvian, and the edible part is mainly the root. Research shows that the maca contains multiple nutritional components such as polysaccharide, polypeptide, branched chain amino acid, mineral elements and the like, and has good effects on improving human metabolism, sexual function, immunity, fatigue resistance and the like; wherein the active ingredient maca polysaccharide can relieve fatigue symptoms and show dose dependence. The mechanism of analysis of anti-fatigue activity may be associated with reduced production of oxidative free radicals, as well as improving disruption of the integrity of the myofiber and mitochondrial membrane biofilms and cell metabolic disorders.
In the prior art, the anti-fatigue drug has great toxic and side effects, so the development of an efficient anti-fatigue product without obvious side effects on human bodies has great significance.
