Description
Technical Field
The invention belongs to the technical field of plant extraction and biological pharmacy, and particularly relates to a preparation method and application of a plant extract for inhibiting xanthine oxidase activity, which has the application in preparing traditional Chinese medicines for reducing uric acid and treating gout.
Background
Xanthine oxidase is a flavoprotein enzyme widely existing in organisms, belongs to a molybdenum protease family, and is a key enzyme of nucleic acid metabolic pathways in the bodies; xanthine oxidase catalyzes the oxidation of the substrates xanthine and hypoxanthine to uric acid, and produces superoxide anion and hydrogen peroxide; hyperuricemia is caused by hyperuricemia, gout attacks can be caused by deposition and crystallization of uric acid at joints, and superoxide anion free radicals are related to inflammation, canceration and aging; research in recent years has also found that xanthine oxidase also plays an important role in ischemia-reperfused tissue and vascular injury, inflammatory diseases and chronic heart failure; hyperuricemia and gout belong to major metabolic diseases of human bodies, and gout patients in China exceed 8 million people.
Because of environmental pollution and food pollution, the human body oxidation is aggravated, the human body immunity is reduced, the resistance is reduced, the human body metabolic disturbance is caused, xanthine oxidase is overactive, the human body metabolizes excessive uric acid, and many people cannot normally discharge the generated uric acid, so that the concentration of blood uric acid is continuously increased, when the concentration reaches the solubility saturation, urate is generated and is crystallized in the kidney and joints to bring severe pain, various uric acid-reducing chemical medicaments have side effects to a certain extent, and particularly, the side effect that the heart, the liver and the kidney have a problem is larger; and the gout can not be cured, so that the gout is repeatedly attacked, and the health of people is seriously harmed.
The oral liquid prepared by a reasonable formula and a certain process technology can obviously inhibit the activity of xanthine oxidase, and fundamentally reduce the formation of uric acid from xanthine and oxygen, thereby radically treating hyperuricemia and gout; the traditional Chinese medicine composition is prepared from medicinal and edible materials, has no toxic or side effect on human bodies, and is a great breakthrough in the technical field of biological pharmacy and medicine.
