Embodiment 1

[0034] The preparation of embodiment 1 Ye Guanmen crude drug medicine

[0035] The traditional Chinese medicine Yeguanmen whole herb is taken as the original drug, pulverized according to conventional methods, sieved to make Yeguanmen fine powder with a particle size of 60-80 mesh, sterilized, and packaged.

Embodiment 2

[0036] The preparation of embodiment 2 night close the door organic solvent extract

[0037] Use 5-10 times the amount of 95% ethanol to extract 2kg of Ye Shumen medicinal material for 3 times, each time for 1-3 hours, combine the extracts, concentrate under reduced pressure to obtain a crude extract, and use 1.4 times the amount of double-distilled water to ultrasonically disperse it for 2 hours Finally, pour it into a separatory funnel, extract it with petroleum ether, ethyl acetate and n-butanol in sequence, shake it fully, let it stand for 6 hours, extract each solvent 3 times, separate the organic phase and the aqueous phase, and use the extract The EYELAN1001 type rotary evaporator concentrates, and the dry paste obtained by extracting samples of petroleum ether, ethyl acetate and n-butanol and the crude ethanol extract are used as screening samples for HIV-1 protease inhibitors in vitro.

[0038] The screening protocol for HIV-1 protease in vitro inhibitors is described...

Embodiment 3

[0057] Example 3 Determination of the inhibitory rate of Ye Shumen extract to HIV-1 protease

[0058] The ethanol extract of Ye Shumen takes 1mg / mL as initial concentration, dilutes with 2 times concentration gradient with 95% DMSO, and the ethanol crude extract obtained in Example 2 is dissolved in 95% DMSO and is formulated into 1.00mg / mL 浓度,用95%DMSO以2倍浓度梯度进行稀释,配制成1.00、0.500、0.250、0.125、0.0625、0.0313、0.0156、0.00780、0.00390、0.00195、0.000977、0.000488、0.000244、0.000122、0.0000610、0.0000305和0.0000153mg For the test sample under the concentration of / mL, the inhibitory rate of the test sample to HIV-1 protease was measured according to the screening scheme of the above-mentioned HIV-1 protease inhibitor in vitro. Specific method: 100 μL of each reaction system, add 97 μL of protein and 1 μL of ethanol extract of Clostridium nigra with different concentrations, mix well, then add 2 μL of substrate to start the reaction, and immediately measure the fluorescence intensity, using Therm...

Abstract

The invention provides the use of the traditional Chinese medicine Yeguanmen and its extract in the preparation of medicaments for treating AIDS. Experiments show that the inhibition rates of the ethanol extract, ethyl acetate extract, and n-butanol extract of Ye Shumen at a concentration of 0.5 mg / mL are 96.8%, 92.7%, and 97.9%, respectively.

Description

technical field [0001] The present invention relates to the application of traditional Chinese medicine, specifically, the present invention relates to the application of Chinese medicine Yeguanmen and its extract, belonging to the field of traditional Chinese medicine. Background technique [0002] Acquired immunodeficiency syndrome (Acquired Immune Deficiency Syndrome, abbreviated as AIDS), also known as AIDS, is an infectious disease caused by human immunodeficiency virus (HIV). HIV virus is a virus that can attack the human immune system. It targets the most important T4 lymphocytes in the human immune system, engulfs and destroys T4 lymphocytes in large quantities, thereby destroying the human immune system and eventually causing the immune system to collapse. It makes the human body fall ill due to the loss of resistance to various diseases, resulting in various infections or tumors, and finally leads to death. [0003] The harm of AIDS has swept the world, and the sp...
