One plant that can be used as an herbal medicine is ceremai leaves. This study aims to determine secondary metabolites and inhibitory zones of ethanol extract, n-hexane fraction and etanol fraction of ceremai leaves (Phyllanthus acidus L.) Skeels) on Salmonella thypi. The extraction of ceremai leaves by maceration method used 96% ethanol was continued by fractionation with n-hexane and ethanol solvents. The results of extracts and fraction of ceremai leaves were then carried out by phytochemical screening test to determine the secondary metabolites found in the sample. Antibacterial activity test method used in this study is the method of wells. Based on the results of the study, phytochemical screening of ethanol extract and ethanol fraction contained saponin, tannin, flavonoid and alkaloid compounds while the n-hexane fraction contained tannin, flavonoid and alkaloid compounds.

Peppermint leaves have been known to have antibacterial and antifungal activity. Amikacin is a semisynthetic derivative of kanamycin which is active against both Gram-positive and Gram-negative enteric bacteria. The combination of plant extracts with antibiotics is one way or alternative to overcome bacterial resistance to antibiotics. The purpose of this study was to determine the combined effect of the ethanolic extract of peppermint (Mentha piperita L.) and amikacin against Klebsiella pneumonia, Staphylococcus aureus, and Escherichia coli as well as the compounds contained in the ethanolic extract of peppermint (Mentha piperita L.) leaves. Antibacterial activity was tested using the disk diffusion method (Kirby Bauer) and the phytochemical screening test using the tube test method. The concentration of peppermint leaf ethanol extract for the combination test was 200 mg/mL and 400 mg/mL, for the concentration of amikacin used was 5 mg/mL with three comparisons made, namely 25:75, 50:50, and 75:25. The results showed a synergistic effect with the largest inhibition zone diameter at a ratio of 25:75 at a concentration of 200 mg/mL, which was 36.25±2.5 mm on Klebsiella pneumonia bacteria. While at a concentration of 400 mg/mL the diameter of the largest inhibition zone was 40±1.63 mm in Klebsiella pneumoniae bacteria with a ratio of 75:25. The results of statistical tests using the t-test showed a significance value of 0.000 0.05 so that there was a significant difference in the administration of each concentration to the resulting inhibition zone. The results of the phytochemical screening test contained alkaloids, phenolic compounds, flavonoids, tannins.

Peel of red dragon fruit (Hylocereus polyrhizus) is one of the plants used as an antibacterial agent as it contains saponin triterpenoid compounds, flavonoid compounds, and alkaloid compounds which can have antibacterial activity. This research aims to determine the antibacterial effect of n-hexane, ethyl acetate, and ethanol fraction of red dragon fruit’s peel against Escherichia coli and Staphylococcus aureus by the concentration of 10mg/ml, 20mg/ml, 40mg/ml, 80mg/ml dan 160mg/ml. This research was conducted by using laboratory experiments. The simplicia was macerated with 96% ethanol and fractionated by n-hexane and ethyl acetate. The phytochemical screening of the fraction was n-hexane fraction containing saponin and alkaloid, while the ethyl acetate fraction contained saponin and flavonoid. Kanamycin was used as a positive control, while DMSO was used as a negative control. According to this research, the MIC value of ethanol fraction, n-hexane fraction, and ethyl acetate fraction were 80mg/ml, 20mg/ml, and 80mg/ml, respectively, for E. coli and all fractions were 10mg/ml for S. aureus. Based on the average diameter of the inhibition zone, the largest diameter zone in E. coli was ethyl acetate fraction with 160mg/ml concentration that was 10,33mm. Meanwhile, in S. aureus n-hexane fraction, it was 160mg/ml, which was 11,20mm. This result showed that the n-hexane fraction has good gram-positive activity while the ethyl acetate fraction has good activity on gram-negative.

Eye Pain

Mekai leaves (Pycnarrhena cauliflora Diels.) (P. cauliflora). Are known to contain flavonoid compounds, tannins and phenolics that act as antibacterial agents and are used in the treatment of eye pain. Staphylococcus aureus (S. aureus) is one of the examples of bacterial diseases of eye pain and also a major cause of many infections in communities and health facilities with cases of resistance to various antimicrobial agents. The purpose of this study was to prove the antibacterial activity of mekai leaves ethanol extract against S. aureus bacteria. This research is an experimental research. The stages of this research began by extracting mekai leaves using maceration method with 96% ethanol solvent. Antibacterial activity was tested by the disc method (Kirby-Bauer) using ethanol extract concentrations of mekai leaves (EPC) 20%, 30%, 40%, 50%, 60%, 70%, and 80%, positive control using 25 μg amoxicillin and negative control using DMSO 10%. The measurement results of inhibition zones of mekai leaf ethanol extract 20%, 30%, 40%, 50%, 60%, 70% and 80% respectively were 8.32 mm, 8.32 mm, 8.32 mm, 8.67 mm, 9.00 mm, 8.67 mm, and 8.33 mm. While the positive control measurement of 25 μg amoxicillin against S. aureus is 28.67 mm and the measurement of 10% negative DMSO control does not produce inhibitory zones, so it can be concluded that the ethanol extract of mekai leaves has antibacterial activity, but the area of inhibition zone produced is smaller than amoxicillin 25 µg. The results of statistical tests using Mann Whitney between negative controls with all EPC concentrations obtained significant differences with p values <0.05, it can be concluded that there is antibacterial activity produced at all EPC concentrations.
