Antibacterial activity and synergism of Artemisia selengensis extract

Recently, researchers from reproductive health and infertility Department of the First Affiliated Hospital of Chongqing Medical University published a paper to study the antibacterial activity of Clarke extract of Artemisia leucophylla (Turcz Ex Bess.) and the antibacterial synergistic effect of Clarke extract on a variety of bacteria when combined with different antibacterial drugs It was pointed out that Artemisia selengensis extract has a certain antibacterial effect The combination of n-butanol and β - lactam antibiotics can enhance the antibacterial effect of antibiotics on different bacteria, and it has the potential of further development and utilization as a new antibacterial sensitizer This paper was published in the Journal of Journal of Zunyi Medical College, No 04, 2014 The antibacterial activity of 70% ethanol extract and its polar parts of Artemisia annua was evaluated by double microporous dilution method The effects of Artemisia annua extract on Staphylococcus aureus, Escherichia coli, Escherichia coli, Escherichia coli were observed by chessboard microporous dilution method and bacterial growth curve method when it was used alone or in combination with ampicillin, benzoxacillin, sultamicillin and cefuroxime sodium The effect of five bacterial strains on the growth of p.pneumoniae, P.aeruginosa and Enterococcus The total extract, ethyl acetate and n-butanol of Artemisia annua showed a certain antibacterial activity against five clinical isolates, and the n-butanol part had the best antibacterial activity alone; more importantly, when the n-butanol part of Artemisia annua with a concentration lower than mic was used in combination with β - lactam antibiotics, it showed a certain synergistic sensitization effect on different bacteria, and it was golden yellow Staphylococcus has the strongest synergism.
