Abstract

The invention discloses use of preparations which takes cress total phenolic acid as a raw material medicine for preparing anti-human immunodeficiency virus drugs. The raw material medicine is extracted from the cress total phenolic acid, and the raw material medicine contains 55-80% of total phenolic acid. Through vitro experiments, the cress phenolic acid has strong anti-HIV activity against HIV; in vivo experiments, the cress total phenolic acid increases percentage of CD4+ T cells, increases the CD4+/CD8+ value, and improves the immunosuppressive effects of the body to play an anti-virus role; the cress total phenolic acid has a good inhibitory effect on the activity of HIV reverse transcriptase. The cress total phenolic acid has the anti-HIV effect in vivo and in vitro, the effect isclear, the anti-HIV effect is achieved by inhibiting the activity of HIV reverse transcriptase, the mechanism of action is clear, and the potential for clinical use development is achieved.

Description

technical field [0001] The invention belongs to the technical field of separating and purifying the effective parts of plants, and can make the total phenolic acid content of the effective parts of cress greater than 50%, reaching the national standard of 5 kinds of raw materials of traditional Chinese medicine; use. Background technique [0002] The team of the present inventors has studied a preparation process of total phenolic acids of cress and a pharmaceutical preparation and application using the total phenolic acids as an active ingredient (patent number 2006100838103) and a preparation process of total phenolic acids of cress and the composition It is used as the pharmaceutical preparation and liver disease application of raw materials (Patent No. 2006101607233), and the extraction process and application of total phenolic acids of cress are initially explored. Commonly used extraction and separation processes are: alcohol extraction-water precipitation-ethyl aceta...
