Description

Hawthorn health food for assisting in reducing blood sugar
The invention belongs to the technical field of health-care food, and particularly relates to a hawthorn health-care food with an auxiliary blood sugar reducing effect.
Background
Diabetes is an endocrine metabolic disease, is characterized by hyperglycemia and secondary disorders of hyperglycemia, such as fat, protein, water, electrolyte and the like, is typically expressed as polydipsia, polyphagia, polyuria and emaciation, and belongs to the category of diabetes of traditional Chinese medicine. With the change of modern diet and life style, the prevalence rate of the disease tends to rise year by year. At present, the main medicines for reducing blood sugar are still western medicines clinically, but the western medicines have more side effects in treatment, and the study on the effect of natural medicine-food homologous raw materials in the aspect of assisting in reducing blood sugar is a modern development trend.
The hawthorn is dry mature fruit of Crataegus pinnatifida or Crataegus pinnatifida of Rosaceae, is sweet and sour in taste and warm in nature, contains multiple vitamins, organic acids such as maslinic acid and the like, and also contains minerals such as flavonoid, lactone, sugar, protein, fat, calcium, phosphorus, iron and the like, has the effects of reducing blood pressure, blood fat and blood sugar and the like, is also an approved plant for food and medicine (homologous food and medicine) by the Ministry of health, has the characteristics of rich resources, wide distribution, low price, easy obtainment and the like, and has great popularization and application values. However, in the process of being applied as a health food, the hawthorn fruit is found to be sour in taste due to the fact that the hawthorn fruit contains various organic acid components such as maslinic acid and the like, on one hand, bad eating experience can be brought to partial consumers, and further application of the hawthorn fruit is influenced; on the other hand, the content of the functional components is lower than that of the extract after extraction, more hawthorn raw materials are required to be added to achieve the same blood sugar reducing effect, and the sour taste of the product is further increased.
The corn stigma is used as a corn byproduct, is rich in active ingredients such as polysaccharide and the like, has the effects of reducing blood sugar and blood fat, is huge in resource, has the advantages of being rich in source, low in price, easy to collect and the like, but is limited in development and utilization at present, most of the corn stigma is discarded in vain, and resource waste is caused. The momordica grosvenori is the fruit of momordica grosvenori which is a perennial root vine plant of cucurbitaceae, belongs to the economic and medicinal plants special in China, and contains a plurality of active ingredients such as flavone, polysaccharide, dulcoside and polyphenol. The wolfberry fruit is a common medicine in various tonifying formulas and has a long clinical application history, wherein the wolfberry fruit polysaccharide is one of the effective components of the wolfberry fruit, can effectively inhibit the activity of alpha-glucosidase and has a certain blood sugar reducing effect. Meanwhile, the corn stigma, the momordica grosvenori and the wolfberry have the effects of reducing blood sugar, and the raw materials have certain sweet taste and sweet mouthfeel, so that the corn stigma, the momordica grosvenori and the wolfberry are easily accepted by consumers.
However, if the raw materials are used independently, the taste of the product is single, and the blood sugar reducing effect of the single component is not obvious. In this regard, although there are numerous documents in the prior art disclosing health food formulations with an auxiliary hypoglycemic effect, such health foods have problems such as the following in terms of the current overall state of the art: (1) in the aspect of health care effect, although the selected raw materials are various, more attention is paid to the blood sugar reducing effect of the raw materials, the research on how to reasonably compound the raw materials to achieve the synergistic effect is less, and the research is proved by experiments; although the prior art relates to the preparation of auxiliary hypoglycemic health-care food by using hawthorn as a raw material, the common medicinal and edible raw materials are also known to have certain hypoglycemic health-care effects, such as corn stigma, fructus momordicae and fructus lycii, but the hypoglycemic effect is often not significant when the raw materials are added independently. (2) In the aspect of eating quality, most of the hawthorn products with the auxiliary blood sugar reducing effect on the market at present have defects in taste and flavor, for example, although the hawthorn raw material has a certain blood sugar reducing effect, the effect is exerted in a limited way when the hawthorn raw material is used alone, and because the hawthorn raw material has the characteristic of sour taste, if the hawthorn raw material is eaten in a large amount, the application of the hawthorn raw material can be influenced because part of consumers are not suitable for the too-acid taste and flavor, meanwhile, the gastric acid secretion is increased when a large amount of hawthorn is eaten, the symptoms of gastric ulcer, gastroesophageal reflux and the like are aggravated, and therefore, the technical task of how to compound the hawthorn raw material to realize the blood sugar reducing effect of the hawthorn and avoid the possible problems is existed. (3) In the preparation method, most of hawthorn products in the market are prepared by directly preparing hawthorn raw materials into hawthorn powder or are prepared into hawthorn powder and then are compounded into a composition for use, active ingredients of the hawthorn powder are not extracted in a targeted manner so as to realize the application of reducing blood sugar, and meanwhile, most of preparation methods adopt general process steps without selecting targeted process conditions and parameter optimization. (4) In addition, the medicinal and edible materials with the effect of reducing blood sugar are known in the prior art to be various and various, and the combined screening is obviously performed one by one, which requires creative labor.

Experiment design:
the blood sugar reducing effect of the health food is proved by the following fasting blood sugar reducing effect.
Materials and methods:
selecting experimental animals: more than 100 healthy Kunming mice (20 +/-2 g) are selected, 1 blank control group, 1 model control group, 1 positive drug control group and administration group (comprising 6 example groups, 6 comparative example A groups and 3 comparative example B groups) are arranged, and 10 mice per group are arranged.
And an experiment for reducing fasting blood glucose:
mice were selected and grouped according to fasting blood glucose levels for 3-5 hours as a blank control group. Except for a blank control group, the rest mice are fasted for 24 hours, are given alloxan 100mg/kg for intraperitoneal injection, are continuously given feed for feeding for 5 days after injection, are fasted for 3-5 hours after injection, and are measured for blood sugar, and the blood sugar value of 10-25mmol/L is the animal success in the hyperglycemic model. Selecting hyperglycemia model animals to be grouped according to the blood sugar level after fasting for 3-5 hours, wherein the test samples with corresponding formulas are respectively gavaged and administered to the groups of examples/comparative examples A/comparative examples B, the administration dosage is 0.5g/kg, and the gavage administration is carried out at the same volume once a day; the model control group is administrated with the same volume of solvent for intragastric administration once a day; the positive drug control group is administered with metformin, the administration dose is 0.5g/kg, and the administration is performed by intragastric administration at the same volume once a day. The administration was continued for 32 days. At the end of the test, animals in each group were fasted for 4 hours and fasting blood glucose was measured. The results are shown in Table 3.
And experimental results
The examples were compared with the control and comparative examples for verification. The results are shown in Table 3:
TABLE 3
Figure 160451DEST_PATH_IMAGE005
The mechanism of tetraoxypyrimidine causing diabetes is that the tetraoxypyrimidine causing diabetes is a specific islet beta cell poison which can selectively damage islet beta cells of normal mice, so that insulin secretion in a body is insufficient, and blood sugar is continuously and stably increased to cause diabetes. Therefore, as can be seen from the results of measuring the fasting blood glucose values in table 3, the examples and comparative examples in which different dosage formulations were added to the fasting blood glucose values have lower fasting blood glucose values than the model control group to which no dosage was added, which indicates that they have significant hypoglycemic effects on mice hyperglycemia caused by alloxan, and suggests that they may have protective effects on insulin β cells, improve insulin secretion defects, and promote insulin β cells to secrete insulin for hypoglycemic effects.
But the quantitative effects of the different formulations were different, wherein the hypoglycemic effects of examples 1-6 of the present invention were equal to or better than those of the positive control group, the effect of the comparative example A/B is worse than that of the positive control group (except for the comparative example B2, the formula of which is the same as that of the example 2), and the auxiliary blood sugar reducing effect of the examples 4-6 is better than that of the examples 1-3 on the whole, which shows that the water extract composition prepared by matching the corn stigma, the fructus momordicae and the medlar and the compound of the water extract composition and the hawthorn alcohol extract have the synergistic effect, it is not a simple additive effect, for example, it is significantly better than the comparative example in the quantified data, and as the actual effect may be significantly different even if the composition of the raw materials is the same in kind but the ratio is different from the above example group (for example, comparative example B3).
By integrating the experimental results, through analysis of variance of data, the measured fasting blood glucose value of the hawthorn health food of the invention has statistical significance, and the experimental result of the embodiment group for reducing fasting blood glucose is judged to be positive, so that the hawthorn health food has a significant auxiliary blood glucose reducing effect; compared with the single use of each raw material and other combination proportions, the formula of the invention has a synergistic effect, and the effect of assisting in reducing blood sugar is achieved, which is beyond the expectation of the technical personnel in the field.
