Enzyme with blood replenishing effect and preparation method thereof
Technical Field
The invention relates to a ferment with a blood replenishing effect and a preparation method thereof, and belongs to the field of medicines.
Background
Blood deficiency belongs to the category of traditional Chinese medicine diseases, refers to a pathological state that blood is insufficient, nutrition and moistening functions of blood are reduced, so that viscera, meridians, body and organs and the like are not nourished, and clinically, the blood deficiency is mainly manifested by pale or sallow complexion, lusterless hair, pale lips, tongue and nails, dizziness, blurred vision, severe fatigue, palpitation, amnesia, insomnia, hypodynamia and the like. The blood deficiency syndrome is not only seen in anemia but also in other diseases such as coronary heart disease, neurosis, viral myocarditis, etc. in the distribution of western medicine.
Modern researches have proved that blood deficiency can cause the decrease of hematopoietic function of bone marrow and peripheral red blood cell content and function, the decrease of immunologic function, the decrease of free radical scavenging ability of organism, even the disorder of secretion of various hormones, the influence of fertility and other serious consequences, and the harm is very large (Guo Ping, blood deficiency syndrome pathological research progress [ J ]. Shandong Chinese medicine journal, 2006, 25 (9): 643-645). Because the pathogenesis of blood deficiency is complex and is often accompanied with pathological changes of a plurality of systems and organs, most of the existing treatment means have poor effect, and some medicines have obvious adverse reaction. For example, for iron deficiency anemia, iron preparations are currently and frequently administered clinically for treatment; however, most of the iron ingested by the human body is difficult to be fully utilized, only a small amount of iron can be absorbed by the body and plays a physiological role, and in addition, the iron preparation often has a gastrointestinal tract stimulation effect, so that the absorption of the medicament is further hindered, and the effect of treating anemia is very small.
Therefore, it is an urgent problem to provide a medicine, health product or food with significant blood-enriching efficacy and no obvious toxic and side effects.
The ferment is a functional microbial fermentation product which is produced by taking one or more fresh vegetables, fruits, mushrooms, Chinese herbal medicines and the like as raw materials and fermenting through a plurality of beneficial bacteria and contains rich nutrient components such as vitamins, enzymes, minerals, secondary metabolites and the like. The ferment not only preserves the inherent nutrient substances in the fermentation raw materials, but also can improve some original bad flavors of the fermentation raw materials, and more importantly, generates some new functional components in the fermentation process, thereby having good health care effect on human bodies.
However, microbial fermentation is a complex process, and factors affecting the quality of enzyme products are many, for example, process parameters such as fermentation strains and inoculation amount have a particularly significant effect on the enzyme quality, and it is very difficult for technicians to determine appropriate fermentation conditions, so as to obtain an enzyme product with good flavor and high content of functional components.

Note: p < 0.05, P < 0.01, compared to model control
The experimental results are as follows: after the mice are exsanguinated and modeled, the mice have the symptoms of blood deficiency, such as slow movement, dyspnea, erect fluffy herb, little luster, pale eyes and tails, and the like; compared with the normal group, the number of the red blood cells and the content of the hemoglobin in the model group are both obviously reduced, which indicates that the model building is successful.
The blood-enriching square group mice are agile in action, normal in hair color and not obviously different from normal group mice; compared with a model group, the number of red blood cells and the content of hemoglobin of the blood enriching formula group are both obviously improved, and the composition has an obvious treatment effect on hemorrhagic blood deficiency.
In addition, the number of red blood cells or hemoglobin content of mice cannot be effectively increased by using the wolfberry extract or the raspberry extract alone compared with the model group; the number of red blood cells or the hemoglobin content of the mice is lower than that of the blood enriching formula of the invention by using the longan pulp extract or the mulberry extract alone.
The results show that the four raw materials of the invention play a synergistic effect and have obvious effect of treating blood loss type blood deficiency.
3. Study on the Effect of chemically blood-deficient mice
Taking 56 mice (Kunming, first level, each half of male and female, the body weight is 18-22 g), dividing the half of male and female into 7 groups at random, administrating the groups as above, injecting acetylphenylhydrazine 20mg/kg and 40mg/kg subcutaneously on the 3 rd day and the 6 th day of administration, injecting cyclophosphamide 40mg/kg intraperitoneally for 5 consecutive days from the 3 rd day, taking blood from the orbit after 1.5h of the last administration, anticoagulating heparin, and measuring WBC, RBC, Hb and HCT values by using an automatic hematology analyzer. The mice were sacrificed after blood collection and the spleen was weighed. The results are shown in Table 2.
TABLE 2 results of the study of the effect of the composition of the present invention on chemically blood-deficient mice (
n=8)
Note: p < 0.05, P < 0.01, compared to model control
The experimental results are as follows: after the mice are subjected to combined molding by the acetylphenylhydrazine and the cyclophosphamide, symptoms of hypokinesia, dyspnea, fluffy herb erection, little luster, pale eyes, ears, tails and the like due to blood deficiency begin to appear on the 4 th day. None of the animals in each experimental group died.
The number of red blood cells, white blood cells, hemoglobin content, hematocrit and spleen weight were all significantly reduced in the model group compared to the normal group. Compared with a model group, the blood enriching formula group has the advantages that the red blood cell number, the white blood cell number, the hemoglobin content, the hematocrit and the spleen weight are all obviously improved, and the effects of resisting bone marrow inhibition caused by cyclophosphamide and promoting the hematopoietic function are shown.
In addition, compared with the single use of the wolfberry fruit extract, the raspberry extract, the longan pulp extract or the mulberry extract, the blood enriching formula group mouse has the advantages that all indexes are in the best level, and the four raw materials play a synergistic effect and have the obvious effect of treating chemical blood deficiency.
