Main Components

Oral hygiene and dental health are very important, there are various kinds of patogen  bacteria in the oral cavity, including the bacteria that cause thrush, Staphylococcus aureus. Gambir is the result of extraction containing polyphenol compounds. The main components contained in gambir consist of alkaloids, flavonoids, tannins and saponins. The use of gambir as a mouthwash preparation is an alternative to replace mouthwash preparations which generally contain an antiseptic in the form of alcohol which can trigger oral cancer. This research is to formulate gambir as a mouthwash and determine the differences in the effectiveness of antibacterial on the growth of Staphylococcus aureus with variations in the concentration of 5%, 10%, 15%. Antibacterial activity test using NA media with agar diffusion method. Physical requirements tests include organoleptic tests, pH tests and viscosity testsshowed that the preparation of 5%, 10% and 15% gambir mouthwash had a pH outside the optimum bacterial growth range of 5. Viscosity of mouthwash preparations of 1.30-5.10 Cp. The antibacterial activity of Staphylococcus aureus in F1 did not produce inhibitory zones, F2 was 5.46 mm, F3 was 9.60 mm and F4 was 10.76 mm while in f5 the positive control was 12.10 mm. Conclusio of this study is gambier mouthwash concentration of 5%, 10% and 15% can inhibit the growth of staphylococcus aureus bacteria.

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.

The antibacterial activity of three Cupressaceae plants (Thujaoccidentalis,ThujaorientalisandChamaecyparisobtusa) was tested against three bacteria using the agar diffusion method. The ether and ethylacetate fraction of crude methanol extract from the three plants showed potent antibacterial activity against the tested microorganisms. The result showed that Staphylococcus aureus revealed the most sensitivity among the tested bacteria. Thujaoccidentalisether fraction and Thujaorientalis hexane fraction exhibited the highest antibacterial activity against Staphylococcus aureus. E. coli was shown the highest MIC values compared to the other two tested bacteria, which indicates the lowest antibacterial activity against the bacterium. This study promises an interesting future for designing a potentially active antibacterial agent from the three Cupressaceae plants.

One of plants used by Indonesian people as a traditional medicine is saga plant (Abrus precatorius L.). This plant has medicinal properties as medication for thrush, cough and laryngitis. Chemical constituents contained in sage leaves which work as antibacterial are flavonoid and saponin. This study aims to determine the optimal concentration of saga leaves extract which can be formulated in a gel dosage form with qualified physical evaluation and has antibacterial activity against Staphylococcus aureus. Saga leaves extract is prepared by maceration method using ethanol 70% as solvent, and then the extract obtained is preliminarily tested to see its antibacterial activity against Staphylococcus aureus with agar diffusion method. Gel formulation for thrush is made with dispersion method in three formulas with variants of active substance concentration that is FI (1%), FII (3%) and FIII (5%). Gel preparation antibacterial activity test is conducted with agar diffusion method as a plate cylinder. Based on this research, it was found that the extract of saga leaves which is positively made is efficacious as antibacterial and can be formulated into a gel preparation for thrush with optimal concentration in F III (5%), this is indicated by widest diameter of the inhibition area against Staphylococus aureus bacteria

Skin infections most often found in developing countries, especially in the tropics, are purulent skin inflammation (pyoderma), the main cause of Staphylococcus aureus. The increasing number of cases of bacteria that are resistant to antibacterial can encourage the extraction of sources of antibacterial drugs from natural ingredients. One of the plants that is thought to have the antibacterial activity of Staphylococcus aureus is the Neem plant. In this study an antibacterial activity test was carried out with the well diffusion method from 96% ethanol extract of Mimba leaves extracted by percolation method. Previously 96% ethanol extract from Mimba leaves had been identified by secondary metabolites by phytochemical screening and standardized extract testing. Standarization using non-specific parameters (moisture content, ash content and drying losses) found that 96% ethanol extract of Mimba leaves entered a range of standard parameters and in phytochemical screening tests obtained 96% ethanol extract of Mimba leaves containing alcaloid, saponins, tannins, steroids / terpenoids and flavonoids. The results of the study on the antibacterial activity test showed a concentration of 75% ethanol extract of 96% Mimba leaves classified as having strong activity, at a concentration of 50% and 25% classified as having moderate activity. Based on this study it can be concluded that the three concentrations of 96% ethanol extract of Mimba leaves were able to inhibit the growth of Staphylococcus aureus bacteria.
