Evaluation of the antibacterial effect of latex Jatropha curcas “piñón” in front of Staphylococcus aureus

Abstract

The present research aims to evaluate the antibacterial effect of Jatropha Curcas latex "Piñón" against Staphylococcus aureus. The disc diffusion method of Kirby Bauer was used in the research, the concentrations of Jatropha Curcas "Piñón" latex were as follows: 10%, 20%, 30%, 40% and 100% using distilled water as solvent. Phytochemical analysis and solubility test were performed on the latex of the plant under study. Jatropha Curcas "Piñón" latex was very soluble in distilled water, ethanol and methanol. According to the phytochemical analysis the latex presented flavonoids, tannins, phenolic compounds, alkaloids and steroids. The concentration of latex at 40% had the highest antibacterial effect at a 95% confidence level and a relative error of 5%.
