Abstract

The invention relates to a method for preparing andrographolide derivatives, and a preparation thereof. The preparation is a salt which consists of Kalii Dethydroandrographolidi Succinas and Adamantanes and has the effect of synergistic interaction. The curative effect of the preparation is better than that of the independent use of Kalii Dethydroandrographolidi Succinas and Adamantanes.

Description

technical field [0001] The invention relates to a salt composed of 14-dehydroxy-11,12-didehydroandrographolide-3,19-disuccinic acid half esters and adamantanes for anti-infection, anti-virus and antipyretic A pain compound, and a preparation method and application thereof belong to the technical field of medicine. Background technique [0002] Andrographis paniculata is the dry aerial part of Andrographis Paniculata (Burm.f.) Nees, a plant of the Acanthaceae family. It has the functions of clearing heat and detoxifying, cooling blood, and reducing swelling. Its main active ingredient is andrographis lactone. Its derivatives after esterification, dehydration, and salt formation can inhibit early capillary permeability increase, inflammatory exudation, and edema, and can specifically stimulate the pituitary-adrenal cortex function, promote the release of ACTH, and increase the anterior pituitary gland. The biosynthesis of ACTH in the middle; it has the function of inactivatin...
