Problems solved by technology

The first category of products will naturally reduce the rise in blood sugar because they eat foods with a low glycemic index. However, for patients who eat three meals a day for a long time, it is difficult to stick to one or a few products, and they have to give up.
The second category of products is more mixed, the mechanism is not clear, the compliance of long-term consumption is low, and the effect of reducing Hb1Ac is not clear, etc.
[0009] Chlorogenic acid has a wide range of sources, but the extraction efficiency of chlorogenic acid in the prior art is not high. Although a large amount of raw materials are used, chlorogenic acid with higher yield or higher purity cannot be effectively obtained.

Abstract

The invention belongs to the technical field of chlorogenic acid preparation, and particularly relates to an extraction method and application of chlorogenic acid. The chlorogenic acid with higher yield and purity is prepared through the extraction steps of green coffee bean extraction, separation, activated carbon purification and the like, the extraction method can effectively improve the extraction efficiency of the chlorogenic acid, and the chlorogenic acid has better effects of reducing blood sugar and blood fat; and the chlorogenic acid can be well applied to products for treating hypertension.

Description

technical field [0001] The technical field of the preparation of chlorogenic acid of the present invention specifically relates to a method for extracting chlorogenic acid. Background technique [0002] The harm of diabetes to the human body is mainly manifested in complications. If diabetes is not well controlled, it will cause chronic damage and dysfunction of the brain, heart, nerves, eyes, kidneys, and nerves, and even lead to disability or death. [0003] For patients with type 2 diabetes, there are generally only two ways to control the disease, drug treatment or weight loss surgery. Drug treatment for diabetes includes oral hypoglycemic drugs and insulin injections. Drugs can be divided into three categories according to different mechanisms of action: stimulating insulin secretion (sulfonylureas and non-sulfonylureas), increasing insulin sensitivity (biguanides, thiazolidinediones), and inhibiting sugar absorption (α-glycosides). enzyme inhibitors). [0004] Ther...
