| 总结: | Helicobacter pylori is a Gram negative bacteria with ahigh prevalence worldwide, causing gastric and duodenal ulcers and cancer, it is one of the main public health problems in Mexico. This work evaluates the in vitro antioxidant, toxic, antibacterial activity, and the ability to inhibit the biofilm formed by H. pylori, of the methanolic extract Juglans regia(EMJR) and crude ethanolic extracts of the species Rosmarinus officinalis (EERO) and Ruta graveolens (EERG) collected in the state of Nuevo León, Mexico. Through phytochemical screening, the presence of secondary metabolites was qualitatively determined. The antioxidant capacity by the DPPH method showed that EMJR was the most active with an IC50of 2.759 μg/mL. The EERG and EERO developed inhibition halos of 11 and 16 mm and a MIC of 0.136 and 0.51 mg/ mL respectively, only the EERO inhibits biofilm formation by 83.7%. Toxicity tests on Artemia salina showed weak to moderate toxicity. The results show the potential use of the studied extracts as alternative sources in the search for new treatments against H. pylori. |
