Abstract

The invention discloses a drug compound for preventing and curing diabetes mellitus, which at least comprises two components including Timosaponin B-II and berberine. Preventing and curing effect can be improved by adding one or a plurality of components from mangiferin, Timosaponin A-III and Timosaponin B-III. The drug compound can also be compounded by anemarrhena extractive and golden cypress extractive, or can be directly extracted from anemarrhena and golden cypress. The drug compound has the advantages of obvious blood sugar reduction effect, and high effective component content, easy quality control. The preparation process of the drug compound is easy for industrialization, and can be applied as drugs to prevent and cure diabetes mellitus.

Description

technical field [0001] The present invention relates to a composition extracted from natural plants, in particular to a composition extracted from Anemarrhena and Phellodendron, for the prevention and treatment of diabetes. Background technique [0002] Diabetes Mellitus (DM) is a series of clinical syndromes caused by absolute or relative insufficiency of insulin in the body. The disease will also cause some complications in the development process, such as: hypoglycemia (Hypoglycemia), ketoacidosis (Ketoacidosis), nonketotic hyperosmolar coma (Nonketotic Hyperosmolar Coma), cardiovascular disease, chronic renal failure, Retinopathy, neuropathy and microvascular disease. There are three main types of drugs commonly used in the treatment of diabetes: biological drugs, such as insulin (Insulin); chemical drugs, such as: sulfonylurea (Sulfonylurea), biguanide (Biguanide), glitazone (Glitazone) and Chinese patent medicine kind. Due to the lack of a relatively mature non-inje...
