Antibacterial Activity of Cold Powder Preparation of (Ethanol Extract) Starfruit Leaf (Averrhoa bilimbi Linn.) Against Propionibacterium acnes

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.

The Stability

Dental caries can be caused by Streptococcus mutans bacteria. Robusta coffee bean extract has an inhibitory effect on the growth of Streptococcus mutans bacteria. Compounds that have antibacterial activity are chlorogenic acid (CGA), caffeine, caffeic acid and trigonelline. Robusta coffee bean extract has the potential to be formulated into mouthwash. This study aims to make a mouthwash formula with the active ingredient of roasted Robusta coffee extract and then evaluate the preparation and test its effectiveness against S. mutans bacteria. Mouthwash preparations were made in 3 formulas with different glycerin concentrations, namely 5%, 10%, and 15%. The stability test of the preparation used the treatment before and after the forced condition. Bacterial inhibition test using agar diffusion method with the positive control, namely commercial mouthwash Chlorhexidine and negative control mouthwash formula without extract content. Data analysis used the Kruskal-Wallis test to determine the differences in each treatment, and the Mann-Whitney test to see which treatment groups were significantly different. The results of the evaluation of the stability of the preparation showed that the three formulations of the mouthwash of roasted Robusta coffee bean extract had organoleptic stability, pH, and viscosity. The results of the inhibitory effectiveness test showed that the mouthwash formulation of formula 1 produced an inhibition zone of 1.6 mm, formula 2 of 2.1 mm, formula 3 of 2.4 mm, positive control of 6.8 mm, and negative control did not produce obstacles zone. It can be concluded that the three mouthwash formulas have antibacterial activity in the weak category (5 mm). The concentration of glycerin in the formula had no significant effect on the stability of the preparation and the antibacterial effectiveness of S. mutans. The results of the inhibitory effectiveness test showed that the mouthwash formulation of formula 1 produced an inhibition zone of 1.6 mm, formula 2 of 2.1 mm, formula 3 of 2.4 mm, positive control of 6.8 mm, and negative control did not produce obstacles zone. It can be concluded that the three mouthwash formulas have antibacterial activity in the weak category (5 mm).

Streptococcus pyogenes is one of the pathogenic bacteria that causes pharyngitis. Natural treatment to overcome these problems is to use cardamom seeds. The purpose of this study was to test the antibacterial activity, determine the concentration of inhibitory zone and phytochemical compounds from ethanol 96% extract of Java cardamom seeds (Amomum compactum Soland. Ex Maton) against Streptococcus pyogenes. The method is used solid dilution and paper disc diffusion method. The solid dilution method is used for the Minimum Inhibitory Concentration (MIC) test with a concentration of 1.25%, 2.5%, 5% and 7.5% while the paper diffusion method is used for the Inhibition zone Diameter (IZD) using five treatments namely three concentrations of ethanol 96% extract of Java cardamom seeds (7.5%, 10% and 12%), one positive control of amoxicillin 0.01 mg/mL and one negative control of sterile distilled water. IZD data were analyzed using ANOVA with a confidence level of 95% and α = 0.05 and Duncan's further tests to determine differences between treatments. The results showed that the MIC was at a concentration of 7.5% while for the IZD test which had the highest activity there was a concentration of 12% with an average inhibition diameter of 12.03 ± 0.14 mm. In addition, ethanol 96% extract of Java cardamom seeds contain alkaloids, flavonoids, terpenoids and tannins which function in antibacterial activity.
