This invention provides a kit for the simultaneous detection of nine flavor nucleotides in livestock and poultry products. The flavor nucleotides are cytidine monophosphate, uridine monophosphate, guanylic acid, inosine monophosphate, adenosine monophosphate, hypoxanthine, inosine, adenosine diphosphate, and adenosine triphosphate. The kit includes: a high-concentration extraction reagent, a standard curve solution, a high-concentration phosphate buffer solution, pH adjustment solution A, and pH adjustment solution B. The high-concentration extraction reagent is perchloric acid; the standard curve solution is a mixed solution of the nine flavor nucleotides; the high-concentration phosphate buffer solution is a solution of potassium dihydrogen phosphate and dipotassium hydrogen phosphate; pH adjustment solution A is sodium hydroxide; and pH adjustment solution B is phosphate. This invention also provides a method for the simultaneous detection of the nine flavor nucleotides using the above kit. This invention enables the simultaneous determination of the content of nine flavor nucleotides in livestock and poultry products. The method is simple, rapid, accurate, and sensitive, and can be used for batch determination, showing good prospects for practical application.

The application discloses application of a 5'-monophosphate nucleotide composition in preparation of anti-aging and longevity drugs and / or functional foods, and belongs to the technical field of medicines.The composition is composed of 5'-monophosphate adenosine, 5'-monophosphate cytidine, 5'-guanylic acid disodium, 5'-uridylic acid disodium and hypoxanthine nucleotide, and the mass ratio of the acid types of CMP, AMP, UMP, GMP and IMP is respectively as follows: CMP: 15-78%, AMP: 6-44%, UMP: 7-40%, GMP: 7-51%, and IMP is 0 or greater than 0 and not higher than 2.5%. The composition can synergistically enhance various mechanisms such as significantly reducing an insulin resistance index, enhancing body anti-coagulation function, improving blood circulation, regulating metabolism of essential minerals such as lithium and copper and regulating intestinal flora ecology, delays aging and prolongs healthy life span. Animal experiment data show that, compared with a control group, the composition prolongs the median survival time of mice by 9.21-12.6%, and the equivalent human life span is 8.76-12.01 years. Human experiment data show that, compared with the control group, the composition intervention reduces the median age of DNA methylation by 3.08 years, and provides a new idea for developing anti-aging and longevity drugs and / or functional foods.
