Compound polysaccharide with functions of clearing heat, nourishing yin and reducing blood sugar, preparation method and application thereof

Abstract

The invention belongs to the field of medicine and health care products, and specifically discloses a compound polysaccharide, a preparation thereof and application thereof in products with the functions of clearing heat, nourishing yin and reducing blood sugar. The compound polysaccharide is prepared from rhizoma phragmitis, lalang grass rhizome, asparagus fern, Radix Ophiopogonis and folium eriobotryae. The preparation method comprises water extraction and alcohol precipitation. According to the compound polysaccharide, the food intake, water intake and urine volume of an internal heating yin deficiency type hyperglycemia rat model can be obviously reduced, and the weight of the rat is increased; the content of insulin is reduced, and the resistance to insulin is improved; triglyceride and total cholesterol are reduced, and the symptom of hyperlipidemia is improved; the immunity indexes, such as cAMP and cGMP, are reduced, and the abnormal phenomena of immunity is improved; the appearance state and spiritual attitude of internal heating yin deficiency rats are improved, the effect is obviously superior to single polysaccharide ingredients, and the compound polysaccharide can be used for preparing medicine or health food with the effects of clearing heat, nourishing yin and reducing blood sugar.

Description

technical field

[0001] The invention belongs to the field of medicines and health care products, and in particular relates to a compound polysaccharide and its preparation method and application, especially a compound polysaccharide with functions of clearing heat, nourishing yin and lowering blood sugar, and its preparation method and application. Background technique

[0002] Hyperglycemia is when blood sugar levels are higher than the normal range. Under normal circumstances, the human body can ensure the balance between the source and outlet of blood sugar through the two major regulatory systems of hormone regulation and nerve regulation, so that blood sugar can be maintained at a certain level. However, under the joint action of genetic factors (such as family history of diabetes) and environmental factors (such as unreasonable diet, obesity, etc.), the two major regulatory functions are disturbed, and blood sugar levels will rise. Short-term, one-time hyperglycemia h...
