Technical Field
The invention relates to the technical field of health care products, in particular to a propolis nutritional composition for enhancing immunity and application thereof.
Background
Immunity is the body's own defense mechanism, and is the body's ability to recognize and destroy any foreign body (virus, bacteria, etc.) that invades from the outside, to treat aged, damaged, dead, denatured self cells, and to recognize and treat mutant cells and virus-infected cells in the body.
Modern immunology considers that immunity is the physiological response of the human body to recognize and eliminate "isohexia". The immune system performs this function in the human body. For millions of years, human lives in an environment which is suitable for living and full of danger, so that the human can survive and also obtains extraordinary immunity. Immunity is therefore said to be a product of the biological evolution process.
The modern civilization brings material enjoyment to human beings, fundamentally changes the original life style and habits of the human beings, and simultaneously brings a great amount of negative effects to the human beings. Various metabolic disorders caused by overnutrition, obstructed toxin excretion in vivo and cardiovascular and cerebrovascular diseases induced; the indoor environment with temperature control in four seasons enables mites, aphids, spores, various bacteria and viruses to propagate in a large quantity, float in the air and enter human bodies through respiratory tracts. Modern furniture, indoor decoration and decorating materials carry harmful carcinogens such as formaldehyde and the like to erode the health of human beings.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
The application provides a propolis nutritional composition for enhancing immunity, which comprises the following components in parts by weight: 10-20 parts of propolis, 60-70 parts of chitosan and 15-25 parts of shark cartilage powder.
Wherein propolis contains flavonoids, terpenes, quinones, esters, alcohols, aldehydes, phenols, organic acids, amino acids, enzymes, vitamins, polysaccharides, trace elements, etc. Propolis has various biological characteristics, wherein bioactive substances playing an important role are flavonoid compounds including flavonoid, flavonol, dihydroflavonoid and the like, and account for about 4.13 percent of the propolis.
The propolis flavone can obviously increase the synthetic amount of total serum protein and antibody of animals to be tested, and obviously enhance the phagocytic capacity of macrophages, so that the propolis flavone can play a beneficial role in thymus, spleen and the whole immune system, and can improve the components of complement and the self-healing capacity of disease resistance of human bodies, so that the immune function of the organisms is in the optimal state of dynamic balance. Propolis has a wide regulating effect on the immune system of an organism, and a large number of reports are made at home and abroad, the propolis can enhance humoral immunity and promote cellular immunity, and can effectively improve the activity, phagocytic capacity and antioxidant capacity of macrophages, reduce the oxidative stress reaction of the macrophages and regulate the secretion of cell factors of the macrophages; increasing the activity of natural killer cells; regulating the activity of polymorphonuclear granulocytes, and controlling the proliferation thereof, thereby improving the immunity of the organism and keeping the immune function of the organism in an optimal state of dynamic balance. Propolis is said to be a natural and highly effective immunopotentiator. Can stimulate the immune function of the organism, enhance the activity of macrophage and improve the immunity of the organism. It has good effects in preventing common cold, cancer, aging, senile plaque and pigmentation.
Propolis can enhance nonspecific and specific immunity of organism, and has certain effect in regulating organism immunity. The propolis has the functions of enhancing the immune function, namely, the propolis has the physiological functions of three aspects of immune defense, immune self-stabilization and immune monitoring, namely, the propolis has the anti-infection capacity of organisms to pathogenic bacteria and viruses, the capacity of identifying and eliminating self-aged tissue cells, and the capacity of killing and eliminating abnormal mutant cells and inhibiting the growth of malignant tumors. Propolis is used as natural immunostimulant, and has effects of enhancing immune system and enhancing activity of immunocyte. For thymus gland, which is the central organ of immune system, propolis can promote the production of a large amount of T cells; propolis can promote spleen to produce a large amount of lymphocytes, has rich B cells, and can secrete special antibodies; has beneficial effects on bone marrow, lymph nodes, etc.
The chitosan has the functions of regulating and improving the immunity of the organism, promoting the generation of antibodies and enhancing the disease resistance of the organism. The chitosan has resistance to pathogens, and can balance sympathetic and parasympathetic nerves. In addition, the chitosan can keep body fluid normal, thereby achieving the purpose of strengthening somatic cells and immunocytes and improving the immunity of human bodies.
The research of the inventor finds that the combination of the propolis and the chitosan has the function of enhancing the immunity, but the enhancing effect of the immunity of the propolis and the chitosan is still poor, so the shark cartilage powder is compounded on the basis of the propolis and the chitosan. Shark cartilage can inhibit chicken embryo vascularization and matrigel-induced angiogenesis, inhibit the growth of breast cancer and human malignant glioma, and prevent the metastasis of breast cancer and Lewis lung cancer. This effect of cartilage may be related to its inhibition of metalloproteases and serine proteases. The shark cartilage contains effective components with endothelial cell specificity, and can reduce the expression of vascular growth factor (VEGF) and its receptor on the surface of microvascular endothelial cell, and inhibit the action of VEGF.
Shark cartilage powder refers to powder made from shark cartilage. The shark cartilage powder has natural effects of promoting regeneration of human cartilage and inhibiting new blood vessel. Shark cartilage contains substances capable of promoting regeneration of human articular cartilage, such as glucosamine, chondroitin sulfate, collagen, etc. These substances are composed in a balanced ratio and can promote the regeneration of human cartilage. The shark cartilage component contains abundant mucopolysaccharide and high-efficiency antibacterial enzyme, so as to stimulate T, B cells and macrophages to attack cancer cells, and improve organism immunity.
In the application, the shark cartilage powder is prepared by the following preparation method:
s1, crushing shark cartilage, adding 1.5% aqueous alkali for soaking, extracting for 13-15h, and carrying out solid-liquid separation to obtain an extracting solution;
s2, adding an acid solution into the extracting solution to adjust the pH value to 8-9, and then adding trypsin for enzymolysis for 1-2 hours at 50-60 ℃;
s3, decoloring and removing impurities from the enzymatic hydrolysate;
s4, adding ethanol into the supernatant to crystallize, collecting the precipitate, continuously adding hydrogen peroxide into the precipitate to perform oxidation reaction for 5-6h, and then adjusting the pH value to 6-7. Then adding ethanol for secondary crystallization, and filtering and drying the crystals.
Wherein the alkaline solution includes but is not limited to NaOH, KOH, Na2CO3、K2CO3One or more of; acid solutions include, but are not limited to, HCl, H2SO4、HNO3One or more of (a).
Specifically, in the present application, the pulverization of shark cartilage comprises the steps of coarsely pulverizing shark cartilage and then freeze-pulverizing the pulverized shark cartilage. The freeze pulverization is carried out at a low temperature (for example, -20 ℃ to-45 ℃) and the pulverization is easier due to the reduced viscosity and elasticity of the shark cartilage under the freezing condition. In the application, the shark cartilage is crushed twice, and the obtained powdery material is easier to extract subsequently. Furthermore, in the application, the shark cartilage is soaked and extracted by the alkali solution, so that the shark cartilage can be fully dissolved for alkali extraction, and then the trypsin can be used for degrading proteins at the intercellular junctions of the shark cartilage, so that the cells are spherical under the tension of the cytoskeleton in the cells, and the cells are separated, thereby being more beneficial to the subsequent extraction process. In addition, the covalent bonding between the protein and the shark chondroitin sulfate can be destroyed by adding the hydrogen peroxide, so that the chondroitin sulfate in the protein is dissociated, impurities such as the protein can be effectively removed, and the purity and the content of the shark chondroitin sulfate sodium are improved. In the application, the purity of the shark cartilage powder can be obviously improved by adding ethanol twice for crystallization. The shark cartilage powder extracted by the specific extraction process has better purity, good stability among batches and better compounding effect with propolis and chitosan.
In addition, the preparation method of the shark cartilage powder is limited, the selection of the propolis is also limited, and the propolis with flavone accounting for 8-18% of the propolis by mass is preferably selected as a main component, so that the immunity is further enhanced.
Preferably, the components comprise the following components in parts by weight: 12-18 parts of propolis, 62-68 parts of chitosan and 17-23 parts of shark cartilage powder. The inventor researches and discovers that when the proportion of the propolis, the chitosan and the shark cartilage powder is in the range, the compounding effect is better, and the synergistic effect is more obvious.
Further, the components in the application also comprise 1-10 parts by weight of auxiliary materials; preferably, the adjuvant comprises one or more of chitosan oligosaccharide, Lac Regis Apis, bee pollen, nucleotide, Concha Margaritifera powder, Ganoderma extract and radix Panacis Quinquefolii extract. When the auxiliary materials are a mixture, the proportion of the components is 1: 1.
The propolis nutritional composition for enhancing immunity provided by the application is in the form of any one of hard capsules, soft capsules and granules. It is to be understood that the above components also include a pharmaceutically acceptable carrier for preparing any of hard capsules, soft capsules, and granules. That is, when the above main ingredients (propolis, chitosan and shark cartilage powder) are prepared into different dosage forms, pharmaceutical excipients or carriers required in the preparation process of hard capsules, soft capsules or granules, and the like can be added according to the conventional process.
The preparation method of the propolis nutritional composition for enhancing immunity is simple, and the main components (propolis, chitosan and shark cartilage powder) are all powdery, so that the main components are directly mixed during preparation, and then the main components are used as main materials to be respectively prepared into any one of hard capsules, soft capsules and granules by a conventional process.
The propolis nutritional composition for enhancing immunity can be widely applied to preparation of health-care food or functional food for enhancing immunity.
The features and properties of the present invention are described in further detail below with reference to examples.
The shark cartilage powder in the following examples was prepared as follows:
firstly, roughly crushing shark cartilage to 60 meshes, then freezing and crushing the shark cartilage to 100 meshes, adding NaOH into the crushed shark cartilage for soaking and extracting for 14 hours, and separating an extracting solution; adding HCl into the extract to adjust pH to 8-9, and adding trypsin for enzymolysis at 55 deg.C for 1-2 hr; after enzymolysis is finished, decoloring and removing impurities from the enzymolysis liquid; and then adding 95% ethanol by mass into the supernatant to perform primary crystallization, collecting the precipitate, continuously adding hydrogen peroxide into the precipitate to perform oxidation reaction for 5-6h, adjusting the pH to 6-7 after the reaction is finished, then adding 95% ethanol by mass to perform secondary crystallization, and performing crystallization, filtration and drying.
