Description

Technical Field

[0001] The invention relates to a composition, in particular to a composition with blood sugar lowering effect, a preparation method thereof and an application thereof. Background Art

[0002] Diabetes is prevalent worldwide and poses a serious threat to people's health. Diabetes often occurs in middle-aged and elderly people, especially those over 40 years old. The incidence rate among young people is also increasing. The incidence rate is higher in overweight or obese people, especially those with abdominal obesity. People with a family history of diabetes, unhealthy lifestyles (such as eating more and moving less, drinking, liking sweets, etc.), high blood pressure, dyslipidemia, coronary heart disease, etc. are also more likely to develop diabetes.

[0003] Strengthen the popular science education of diabetes and improve the public's awareness and attention to diabetes. Promote a healthy lifestyle, such as a reasonable diet, moderate exercise, quitting smoking and limiting alcohol consumption, to prevent the occurrence of diabetes. For patients with diabetes who have been diagnosed, active treatment and blood sugar control should be carried out to reduce the occurrence of complications and improve the quality of life. The epidemiological characteristics of diabetes are high incidence, obvious and diverse patient characteristics, and severe epidemic trends.

[0004] Traditional Chinese medicine believes that diabetes belongs to the category of "quenching thirst", with Yin deficiency as the root and dryness and heat as the symptom. Yin deficiency refers to the lack of Yin fluid in the body, and dryness and heat are caused by Yin deficiency. Yin deficiency and dryness and heat lead to dysfunction of internal organs, especially the lungs, stomach, and kidneys, which are the most seriously damaged. Lung dryness will cause the body fluid to not be distributed, stomach heat will digest food and make people hungry, and kidney deficiency will cause water to not transform into gas, thus causing symptoms of thirst. Yin deficiency and internal heat will damage body fluid, blood vessels will be weak and astringent, qi and yin will be deficient, internal organs will not be nourished, and yin and yang will be deficient. Long-term illness will enter the collaterals, blood vessels will be stagnant, resulting in poor circulation of qi and blood, obstruction of internal organ function, and thus aggravating symptoms of thirst.

[0005] Currently, most traditional Chinese medicines for diabetes are single prescriptions and proven prescriptions. The amount of medicinal ingredients in compound prescriptions is large, and the basis for the formulation of traditional Chinese medicines is different, and the treatment principles are not unified. Therefore, based on traditional Chinese medicine and according to the pathogenesis of diabetes, we actively seek and explore efficient and non-toxic treatments for this disease.

[0006] Traditional herbal medicine records that marine shellfish have multiple functions. "Chinese Materia Medica" records that dried scallops are sweet, salty, and slightly warm; "Dietary Materia Medica" records that clam meat is sweet, salty, and cold, and can cure irritability and thirst; razor clam meat is sweet, salty, and cold, and can cure irritability and thirst; "Compendium of Materia Medica" records that oyster meat is sweet, warm, and non-toxic, and can cure irritability and thirst after drinking. Modern research shows that shellfish are mainly composed of protein components, which can release a variety of bioactive peptides after enzymatic hydrolysis, among which hypoglycemic active peptides are particularly concerned. Under the guidance of traditional Chinese medicine theory, the present invention studies pearl oyster soft tissue and develops health products with hypoglycemic activity. Summary of the invention

[0054] Instruments: Omron blood glucose meter HGM-112 (Suzhou Erda Medical Equipment Co., Ltd.); Omron blood glucose test strips (Suzhou Erda Medical Equipment Co., Ltd., batch number: 1620A2112C).

[0055] Animal grouping: db / m mice were the blank group, and db / db mice were randomly divided into the model group, the positive drug sitagliptin hydrochloride metformin group, the low-dose group of the composition of Example 1 (300 mg / kg), and the high-dose group of the composition (900 mg / kg) according to blood sugar, with 8 mice in each group. The blank group mice were given ordinary maintenance feed, and the remaining mice were given high-fat feed. Each group was given once a day for 28 consecutive days, and the blank group and the model group were given an equal volume of normal saline.

[0056] Determination of fasting blood glucose (FBG): After the start of drug administration, fasting blood glucose was measured every 7 days. Before measurement, the mice were fasted (but not water-deprived) for 12 hours, and blood was collected by cutting their tails. The second drop of blood was dripped onto a blood glucose test strip, and the fasting blood glucose of the mice was measured using a blood glucose meter.

[0057] Oral glucose tolerance (OGTT): On the 24th day of administration, the oral glucose tolerance of mice was measured. Before the experiment, mice were fasted overnight (water was not allowed) for 12 hours, and their fasting body weight was measured and their fasting blood glucose was measured. After the mice recovered for 30 minutes, they were given 20% glucose solution by gavage at 0.1ml / 10g. Blood samples were collected from the tail vein of mice at 30, 60, 90 and 120 minutes after gavage, and blood glucose values ​​were measured using a blood glucose meter and blood glucose test strips.

[0058] Determination of insulin tolerance (ITT): On the 26th day of administration, the insulin tolerance of mice was determined. Before the experiment, mice were fasted (water was not allowed) for 4 hours, and their fasting body weight was measured and their fasting blood sugar was measured. After the mice recovered for 30 minutes, 0.75U / kg insulin injection was intraperitoneally injected at 0.1ml / 10g. Blood samples were collected from the tail vein of mice at 30, 60, 90 and 120 minutes after gavage, and blood sugar levels were measured using a blood glucose meter and blood glucose test strips.

[0059] 2. Results
