Abstract

The invention relates to application of clausena lansium leaves to preparation of alpha-glucosidase inhibitor products. The clausena lansium leaves are dried leaves of a rue family clausena plant clausena lansium (Lour.) Skeels. The invention further provides a composition with an alpha-glucosidase activity inhibiting effect. The composition comprises a clausena lansium leaf raw medicinal material or medicinal slices or extract of the material and other traditional Chinese medicinal materials such as coptis chinensis, panax ginseng and safflower carthamus. The composition or a preparation of the composition can be used for inhibiting the alpha-glucosidase activity, and reducing or assisting in reducing postprandial blood sugar or preventing and/or treating obesity clinically. The composition can be used as health-care food or food, and is high in safety. The preparation method is simple, and the product with the clinical effect can be obtained by adopting a conventional extraction and separation technology.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to the new application of leaves of wampum bark as an α-glucosidase inhibitor, which can be used to prevent and / or treat diabetes or obesity. Background technique [0002] For many years, sulfonylureas and biguanides have been the main drugs used to treat diabetes clinically. In animal experiments, sulfonylureas only lowered blood sugar in normal mice, but were ineffective for alloxan hyperglycemic mice; biguanides Because of increasing the anaerobic glycolysis of sugar, similar drugs can cause different degrees of increase in blood lactic acid, and sometimes even cause serious consequences of blood lactic acidosis in patients. Although both have good effects on lowering fasting blood sugar, their effect on lowering postprandial blood sugar is very limited. Postprandial blood sugar in diabetes is the highest stage of blood sugar level in a day, and its duration can be as long as 8...
