Description

NMN-containing composition capable of delaying senescence and preparation method and application thereof
Technical Field
The invention relates to the technical field of food health care, in particular to a composition containing NMN and capable of delaying senescence, and a preparation method and application thereof.
Background
Aging, also called aging, is an unavoidable stage in life, is a spontaneous inevitable process of all multicellular organisms over time, has harmful changes at all levels of organisms and tissues, shows a decline process of functions, adaptability and resistance, and can be divided into physiological aging and pathological aging, wherein the physiological aging refers to gradual irreversible degenerative change of a complex morphological structure and physiological functions of the whole body, influenced by genetic factors, of an organism from the beginning of the maturation stage and along with the aging, also called normal aging. Pathological aging refers to accelerated aging caused by diseases or abnormal factors, also called abnormal aging. Aging is closely related to senile diseases, and the more serious the aging degree is, the greater the probability of the disease is. Aging is a continuous dynamic and slowly progressive process, which gradually starts from the end of the growth period, and the influence of the aging is gradually shown by the dysfunction, the decline of organ functions, the cell degeneration and the change of protein and enzyme activity of a human body system in the old period, mainly showing that the adaptive capacity of the organism to the environmental stimulation is weakened or even lost, and the decline of various tissue and organ functions appears; with the continuous development of medical level and scientific technology, human beings have conducted many studies on aging mechanism and life-prolonging and anti-aging method, and there is an urgent need to develop better dietary or pharmaceutical intervention measures for aging and aging-related disease mechanism.
beta-Nicotinamide Mononucleotide (NMN) is used as one of important precursors of mammal NAD +, and the in vivo generation reaction depends on the catalytic action of nicotinamide ribotransferase phosphate compounds, wherein the NMN in human bodies is mainly derived from foreign food intake and self-synthesis of organisms; research finds that artificial supplementation has a plurality of advantages, on one hand, in peripheral tissues and organs, the endocrine of the body is regulated, and the retinal degenerative disease is treated; improving and repairing islet sensitivity, promoting insulin secretion, and preventing and controlling metabolic diseases such as type II diabetes and obesity; protecting heart and kidney, treating cardiovascular diseases and acute renal injury, and treating brain injury and apoplexy in central nervous system, and repairing mitochondrial respiratory function deficiency of brain. In fact, one of the hallmarks of aging is the development of neurodegenerative diseases. Our common neurodegenerative diseases such as alzheimer's disease, parkinson's disease, huntington's disease, amyotrophic lateral sclerosis and frontotemporal dementia have increased susceptibility with age. Research shows that the artificial NMN supplementation can play a certain saving role in AD, PD and other neurodegenerative diseases. More importantly, NMN has non-toxic characteristics. The results show that NMN has important potential as an effective anti-aging intervention means.
In the prior art, most of products with anti-aging efficacy adopt a traditional Chinese medicine formula, but the traditional Chinese medicine formula has complex components, the efficacy and the toxic and side effects are easy to question, and although other anti-aging products on the market can enhance the function of a human body to a certain extent, the using effect is not ideal, and the anti-aging effect needs to be enhanced.

As can be seen from Table 1, at the end of the experiment, the mice in the D-galactose aging model group had an aging state, which is mainly characterized by dark hair, lassitude, weakness of limbs, reduced activity, relatively small vitality felt during grabbing, easy grabbing, and reliable modeling of the aging model mice; the weight of the mice in the D-galactose aging model group increased slowly compared to the normal control group, and the experimental group fed with the composition physiological saline solution promoted the slow weight increase of the mice in the D-galactose aging model group to be higher than that in the galactose aging model group, but the increase was still lower than that in the normal control group.
TABLE 2 changes in thymus index and spleen index in each group of mice

Note: comparison with normal control group: ) P < 0.05; comparison with model groups: 2) p < 0.05;
thymus and spleen are important immune organs of the body and show more obvious change-degeneration phenomenon along with age than other organs, namely the body mass index of the thymus and the spleen is reduced, so that the thymus and the spleen are atrophied and regarded as the symptoms of the body aging; as can be seen from Table 2, the thymus index and spleen index of the D-galactose-senescent group were both significantly lower than those of the control group (P < 0.05); the thymus index and spleen index of the experimental group are obviously higher than those of the model group (P <0.05), experiments show that the composition has the weight-gaining effect on thymus and spleen of immune organs of mice, and the composition of the experimental group has the effect of delaying thymus and spleen wilting aging.
GSH is one of important antioxidants and free radical scavengers in vivo, can effectively relieve oxidative damage in organisms, and the content of GSH can measure an important index of the oxidation resistance of the organisms; MDA is a product of lipid peroxidation initiated by free radicals in the body and is commonly used to assess the degree of aging; SOD is an important antioxidant enzyme in vivo, can effectively remove superoxide anion free radicals, and generates hydrogen peroxide; CAT can decompose hydrogen peroxide, and can cooperate with SOD to completely remove superoxide ions, reduce MDA and free radical metabolites, and prevent cells from being broken;
as shown in fig. 1-4, compared with the normal control group, the activities of superoxide dismutase-SOD, peroxidase-CAT and reduced glutathione-GSH in serum, brain tissue and liver of the D-galactose aging group are significantly reduced, and the malondialdehyde-MDA content is significantly increased; compared with the D-galactose aging group, the activity of superoxide dismutase-SOD, the activity of peroxidase-CAT and the activity level of reduced glutathione-GSH in serum, brain tissues and liver in the experimental group are obviously improved, the malondialdehyde-MDA content is reduced, and statistical difference exists; the results show that the composition of the invention can enhance the activity of antioxidant enzyme in serum and organs, inhibit the growth of free radicals by improving the activity of free radical scavengers in the body, reduce lipid peroxidation and protect tissues from the attack of oxidants and free radicals, thereby playing the role of anti-aging.
