[0019] To screen traditional Chinese medicine formulas that have inhibitory or therapeutic effects on acne bacilli (anaerobic bacteria).

[0020] 1) Nano-Fe-Ta-Cu-B immunoprobe preparation:

[0021] Fe-Ta-Cu-B nanoparticles can be purchased from the market, or can be synthesized by physical or chemical methods with reference to literature.

[0022] Silica-coated nano-Fe-Ta-Cu-B: take 47.5g of sodium silicate, dissolve it in a beaker with deionized water, and adjust the pH value to 12-13 with hydrochloric acid. Take 5.0g of nano-Fe-Ta-Cu-B and add it into the beaker, and stir mechanically (with a glass rod) for 5min. The mixture was sonicated for 30 min and stirred in due course. Raise the temperature to 85˚C, add hydrochloric acid dropwise to adjust the pH value to 6-7, and form a precipitate. While magnetically separating, wash the precipitate with deionized water for 3-4 times. Then, the precipitate was dispersed in 250 mL of methanol. The above process is repeated thre...

Abstract

The invention provides a method for screening an anaerobion traditional Chinese medicine inhibitor based on a Fe-Ta-Cu-B nanoprobe, and belongs to the technical field of development and application of traditional Chinese medicine. The method is characterized in that the Fe-Ta-Cu-B nanoprobenanoprobe is prepared and used as the basis for screening an anaerobion traditional Chinese medicine formula; the property that a paramagnetic Fe-Ta-Cu-B nanoprobenanoprobe prepared by antibody-coating is capable of performing specific binding with target bacteria and the influence of the paramagnetic property of Fe-Ta-Cu-B on nuclear magnetic resonance relaxation time are utilized for detecting whether a sample contains the target bacteria. The paramagnetic Fe-Ta-Cu-B nanoprobe shows a linear relation with the nuclear magnetic resonance relaxation time within a certain range, that is, if the nano Fe-Ta-Cu-B content is high, the nuclear magnetic resonance spin-lattice relaxation time and spin-spin relaxation time of the sample are small, and the target bacteria can be quantitatively detected within a certain range, and as a result, the bacteria inhibition effect of the traditional Chinese medicine formula can be indirectly assessed. The method is applicable to the screening of the traditional Chinse medicine formula capable of inhibiting anaerobion; and the development of a traditional Chinese medicine product is sped up.

Description

technical field [0001] The invention relates to a screening method of traditional Chinese medicine formula. Background technique [0002] Antibiotics can also cause damage to the human body while sterilizing bacteria, affecting liver, kidney function, and gastrointestinal tract reactions. Abuse of antibiotics may lead to the occurrence of drug resistance in some bacteria, and the treatment of infections will become very difficult. At present, there is almost no antimicrobial drug without drug resistance. It is of positive significance to develop traditional Chinese medicines and formulas with antibacterial effects. [0003] Many traditional Chinese medicines and prescription medicines have antibacterial and anti-inflammatory effects, and the active ingredients and molecular structures of some Chinese herbal medicines have also been fully or partially studied. For example, berberine (berberine), the main component of Coptis chinensis and Phellodendron phellodendron for dys...
