The researchers studied four native Mexican plant extracts, Cordia boissierie, Larrea tridentata, Leucophyllum frutescens, and Schinus molle. Each of the plant extracts tested the Gram-positive bacteria Staphylococcus aureus for their extraordinary ability to develop resistance to antibiotics. Researchers say that medicinal plants are increasingly seen as a potential source of new antibacterial drugs because of their small phytochemical and toxic effects.
After the anti-staphylococcus test on the four plant extracts, it was found to have antibacterial activity against Staphylococcus, and the bactericidal activity and antibacterial activity were higher than those of the control group. The control group was 70% ethanol, kanamycin at a concentration of 50 mg/ml, and chloramphenicol at a concentration of 34 mg/ml. Trifolium repens and hawthorn extract have better inhibition. These plants have enormous antibacterial potential.
More importantly, all extracts can be absorbed without affecting the formation of active antimicrobial PVOH biofilms. The higher the concentration of the extract in the biofilm, the more obvious the inhibition of Staphylococcus aureus. The results also show that the extract has antibacterial activity against Gram-negative bacteria such as Salmonella and Escherichia coli.
