Abstract

Background: Staphylococcus aureus is a gram-positive bacteria that can cause infection. One of the plants that has antibacterial activity is jatropha leaves which contain flavonoids, saponins, tannins, alkaloids, steroids and polyphenols. Purpose: To determine the antibacterial activity of ethanol extract and ethyl acetate fraction with concentrations of 30%, 60% and 100% against Staphylococcus aureus bacteria. Method: The method for extracting jatropha leaves is maceration with 96% ethanol solvent and the fractionation method, namely liquid-liquid fractionation with ethyl acetate solvent. Antibacterial activity test was carried out in vitro with the disc diffusion method and compared the mean zone of inhibition of each treatment with a positive control (gentamicin 10 μg). Result: The results showed that the ethanol extract and ethyl acetate fraction of jatropha leaves had a strong resistance response, while the positive control gave a very strong inhibitory response to the growth of S. aureus bacteria. Based on the one way ANOVA test, ethanol extract and ethyl acetate fraction showed a significant difference from each treatment with a significant value (P=<0.05). Conclusion: The ethanol extract of Jatropha leaves can inhibit the growth of S. aureus bacteria at a concentration of 100% (18.28 ± 0.50 mm), 100% concentration of ethyl acetate fraction (15.10 ± 0.12 mm). The ethanol extract provided the best inhibition power, namely 18.28 ± 0.50 mm and a positive control 21.82 ± 0.092 mm.

Abstract

Background: Typhoid fever is caused by Salmonella typhi bacterial infection which spreads via the faecal-oral route and has epidemic potential. Salmonella typhi is a Gram-negative bacterium in the Enterobacteriaceae family. Currently, the use of natural ingredients can be an alternative treatment for typhoid fever, one of which is the mangosteen stem skin (Garcinia mangostana L.). Purpose: To determine the antibacterial activity of mangosteen stem skin fraction against Salmonella typhi ATCC 13311. Method:The maceration method was selected using methanol solvent and fractionation by ECC using ethyl acetate and n-hexane as solvents. This study used five treatments (fraction with a concentration of 20%, 40%, 80%, chloramphenicol 30µg as a positive control, and DMSO as a negative control) which tested their antibacterial activity against Salmonella typhi ATCC 13311 by disc diffusion. Result: The results showed that the ethyl acetate fraction of mangosteen stem skin had the greatest average inhibition zone, that is 13.86 ± 0.72 mm compared to the n-hexane fraction of mangosteen stem skin with an inhibition zone of 10.43 ± 0.73 mm. The data obtained were then analyzed with One-way ANOVA. Conclusion: The results obtained were p=0.000 (sig <0.05), indicating that there was a significant difference between the ethyl acetate fraction and the n-hexane fraction with 20%, 60%, and 80% concentrations with positive control
