Abstract

The invention relates to the application of a prunus mume extract, and belongs to the field of biomedicines. The extract is obtained by extracting prunus mume with organic solvent, performing liquid extraction with organic solvent, and optionally refining; and can be used for preparing anti-HIV and antibacterial drugs. The inventive drugs have the advantages of high bioavailability of plant, good therapeutic effect, easily accessible raw material, and good safety. Researches and developments on the pharmacological activity of the extract are of great significance, and the extract has wide application prospect.

Description

technical field [0001] The invention relates to biomedicine, in particular to a plum extract used for anti-AIDS virus and antibacterial. Background technique [0002] The disease caused by HIV infection is called AIDS, and its full name is acquired immunodeficiency syndrome (acquired immunodeficiency syndrome, AIDS). + The number of cells decreases, followed by opportunistic infections, tumors, etc., and the clinical manifestations are various. The disease spreads quickly, has a high fatality rate, and is currently incurable, which has attracted the attention of governments and societies in various countries. [0003] Two types of HIV have been identified, namely HIV-1 and HIV-2. Both have similar viral structures and transmission routes. HIV-2 is mainly distributed in West Africa and has also been detected in some infected people in Europe and the Americas. Its virulence and transmissibility are lower than that of HIV-1, and the course of AIDS caused by it is slower and...
