Problems solved by technology

Although these methods can quickly improve the clinical symptoms of diabetic patients, long-term medication will lead to drug resistance in the body, and this type of drug will cause serious damage to the liver, kidney and other organs. For example, sulfonylurea drugs can promote insulin synthesis and secretion, But long-term use can cause side effects such as hypoglycemia and weight gain; thiazolidinediones can improve insulin sensitivity and promote glucose absorption and utilization, but long-term use can cause liver toxicity, weight gain, fluid retention and bone loss, etc. Adverse reactions

Abstract

The invention provides a coconut haustoria polysaccharide with anti-oxidation and hypoglycemic effects and a preparation method thereof. The preparation method comprises the following steps: pretreatment of raw materials, vibration extraction, concentration, protein removal, decolorization, alcohol precipitation, and vacuum freeze-drying . The coconut haustoria polysaccharide prepared by the present invention has the advantages of simple operation, short process, large output, high safety, and outstanding efficacy. The prepared haustoria polysaccharide is a pure natural non-toxic plant polysaccharide, has anti-oxidation effect, and can also promote liver cells to increase glucose Consumption, which has the potential to lower postprandial blood sugar, can be used as a potential drug resource for II diabetes treatment.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a coconut inhaler polysaccharide with antioxidative and hypoglycemic effects and a preparation method thereof. Background technique [0002] Diabetes mellitus, known as "diabetes syndrome" in traditional Chinese medicine, is a global endocrine and metabolic disease characterized by elevated blood sugar levels and typical symptoms of "three more and one less", polydipsia, polyphagia, and polyuria and weight loss. Diabetes is generally divided into type I, type II, gestational diabetes and other diabetes according to the cause of the disease, among which type II diabetes accounts for more than 95%. Type II diabetes is a polygenic hereditary disease characterized by relatively insufficient insulin secretion and insulin resistance. It can directly damage islet beta cells, or activate some stress-sensitive pathways as signaling molecules, regulate the expression of related facto...
