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.

Identification of secondary metabolites, antibacterial and antioxidant activities assay of methanol extract of sea cucumber Stichopus hermanii were conducted from May to July 2011 at the Natural Products Laboratory, Research Center for Oceanography, Indonesian Institute of Sciences. Sea cucumber used in this study comes from South Lampung waters. Objective of the study was to get information of secondary metabolites, antibacterial and antioxidant activities of methanol extract of sea cucumber S. hermanii. The extraction method which used in this experiment was the maceration method using methanol solvent. Identification of secondary metabolites was performed through observing reaction of colors, precipitation, and foaming. Antibacterial and antioxidant activities of methanol extract from sea cucumber were tested using agar diffusion method and reducing of free radicals 1.1-Diphenyl-2-Picrylhydrazyl (DPPH) respectively. The results showed that secondary metabolites identified in the methanol extract of sea cucumber S. hermanii were saponin and steroids. Both secondary metabolites had antibacterial activities against Staphylococcus aureus, Vibrio eltor and Bacilus subtilis. The analysis of antioxidant activity showed that the IC50 value of methanol extract of sea cucumber S. hermanii was about 65.08 ppm. It indicated that S. hermanii is having potency as antibacterial and antioxidant. Keywords: antibacterial, antioxidants, sea cucumber Stichopus hermanii, secondary metabolites

L) against S.aureus and E.coli; using agar diffusion method was carried out in order to produce the extract. The extract was collected using maceration method. The concentration of extract was 7,8125; 6,1035; 5,00; 4,8828; 4,3944; and 3,90625 mg/mL. The results showed that both of extracts had antibacterial activities. Ethanol extract of white flesh of fruit guava leaf had (Minimum Inhibitory Concentration) MIC value at 5.000 mg/mL against S.aureus and 4.8828 mg/mL against E.coli. Whereas ethanol extract of red flesh of fruit guava leaf had MIC value at 4.3944 mg/mL against S.aureus and E.coli.  MIC value of ethanol extract of white flesh of fruit guava leaf is equal with MIC value of clindamicin concentration at 3.00 µg/mL against S.aureus, and 1.00 µg/mL against E.coli. The MIC value of red flesh of fruit guava leaf is equal to the MIC value of clindamicin concentration at 3.00 µg/mL against S.aureus, and 1.00 µg/mL against E.coli.

           The purpose of this research was to identified the compounds in ethanol extract of soursop flower and determined the antibacterial activity of the soursop flower extract on Salmonella enteritidis. The phytochemistry screening was done to identify the secondary metabolite compounds of this extract. The concentrations used of ethanol extract of soursop flower were 10%, 20%, 30%, 40%, 50%, with ampicillin 10 μg/disc as the positive control and 10% Dimethyl Sulfoxide (DMSO) as the negative control. The antibacterial activity test of soursop flower ethanol extract against Salmonella enteritidis was held in vitro using the paper disc diffusion method by measuring the diameter of the inhibition zone. The phytochemistry screening showed that the ethanol extract of soursop flower had secondary metabolites such as alkaloids, phenolic, and flavonoid. The result of the antibacterial activity test showed that there was no inhibition zone (bright zone) at various concentrations. So, it can be concluded that soursop flower ethanol extract (Annona muricata L.) contained the secondary metabolites such as alkaloids, phenolic, and flavonoid, and also this extract had no antibacterial activity against Salmonella enteritidis

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.
