Nigella sativa L. was allegedly to has antibacterial effect. The aim of this research is to investigate antibacterial effect of ethanolic extracts of 96\% Nigella sativa L. from Indonesia toward Staphylococcus aureus, Pseudomonas aeruginosa and Streptococcus epidermidis. The Antibacterial activity of of Nigella sativa L toward Staphylococcus aureus, Pseudomonas aeruginosa and Streptococcus epidermidis using the well method. The 96\% ethanolic extract of 12,5; 25;50 and 100\% (mg/ml)inhibit growth of Staphylococcus aureus (with inhibition zone 11.06; 29.58; 28.22; 30.84 mm respectively) and Streptococcus epidermidis (20.90; 31.90; 29.93; 33.07 mm respectively). Ethyl acetate fraction of 96\% ethanolic extract of Nigella sativa concentration of 6,25; 12,5; 25;50 and 100\% (mg/ml) inhibit growth of Staphylococcus aureus (12.91; 15.06; 19.19; 37.48; 46.18 mm respectively and Streptococcus epidermidis (19.07; 19.21; 20.22; 21.62; 40.00 mm respectively). Ethanolic 96\% extract and ethyl acetate fraction of ethanolic extract of Nigella sativa have antibacterial effect toward Staphylococcus aureus and Streptococcus epidermidis invitro.

Background: Cassia fistula L. has been traditionally used to cure skin diseases. That disease can be caused by various bacteria, such as Propionibacterium acnes and Pseudomonas aerugniosa. Objective: the objective of this research was to formulate cream containing active fraction of Cassia fistula bark and to study the antibacterial activity as well as physical stability of the active substance after formulation. Materials and Methods: The cream base were oilin- water (O/W) and water in oil (W/O) type. Antibacterial activity test had been performed by using agar diffusion method. Determination of Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were conducted by microdilution method. The active fraction was formulated into creams with concentration of 4 -6x MIC. Physical evaluation of creams including organoleptic, pH, viscosity, TLC (Thin Layer Chromatography) profiling and antibacterial activity against both tested bacteria were evaluated during 28 days of storage. Results: The results showed that ethyl acetate fraction was the most active, having MIC and MBC values of 175 and 350 ppm respectively against P. acnes, while those against P. aeruginosa were 400 and 800 ppm. Optimation on creams using different type of cream bases showed that either O/W or W/O creams remained stable during 28 days of storage in terms of organoleptic and pH. The viscosity increased in O/W and decreased in W/O type. Qualitative analysis by TLC profiling showed that the ethyl acetate fraction of Cassia fistula as chemical compounds in creams was relatively stable as the profile remained the same after 28th day of storage. Result of antibacterial activity test on cream with O/W base was unchange after 28 day, while that with W/O revealed no activity which may due to poor diffusion within the cream base as media. Conclusion: active fraction of Cassia fistula can be formulated into cream with O/W cream base system.

Aim: Screening of natural extracts is a focused intensive study that aims to find active principles sorted from plant resources both safe and environmental friendly. The present study was aimed to evaluate the antibacterial activity of direct crude extracts of Carica papaya leaves and Allium sativum cloves alone and in combination against multiple drug resistant strains. Methods: Two Gram positive (Staphylococcus aureus and Bacillus cereus) and three strains of Gram negative (Escherichia coli, Salmonella typhi and Pseudomonas aeruginosa) bacteria were used to evaluate the antibacterial activity of Carica papaya leaves and Allium sativum using Agar Disk Diffusion Method. Results: The results of this study showed that both extracts showed moderate antibacterial activity against the test bacterial strains and the potency of the extracts was increased when these two extracts were combined. Conclusion: These extracts directly can be used as natural alternative preventives to control various food poisoning diseases and preserve food stuff avoiding healthy hazards of chemically antimicrobial agent applications.

Context: One strategy to address the emergence of infectious diseases supported by the increasing cases of microbial antibiotic resistance is the development of anti-pathogenic drugs, a quorum quenching compound(s) capable of inhibiting microbial communication (quorum sensing inhibitor). Pseudomonas aeruginosa is one of the most common source of chronic opportunistic infections, which demonstrates the most consistent resistance to antimicrobial agents. Quorum sensing (QS) controls secretion of virulence factors in P. aeruginosa. Aim: This study aims to discover quorum sensing inhibitors (QSI) from some Indonesian medicinal plants ethanol extract to analyze their inhibitory activities against QS-mediated virulence factors in P. aeruginosa. Settings and Design: In-vitro experimental study-laboratory setting Material and Methods: Indonesian medicinal plant ethanolic extracts were tested for their capability to inhibit P. aeruginosa motility, biofilm formation using microtiter plate method, pyocyanin and LasA production using LasA staphylolytic assay. Statistical analysis used: Statistical significance of the data were determined using one way ANOVA, followed by Dunnett\’s test. Differences were considered significant with P values of 0.05 or less. Results: Ethanolic extract of T. catappa leaves and A. alitilis flower capable to inhibit P. aeruginosa motility as well as pyocyanin production and biofilm formation. Both extracts also showed capability in reducing LasA protease production. Conclusion: T. catappa and A. alitilis are an interesting sources of innovative plant derived quorum quenching compound(s), thus can be used in the development of new antipathogenic drug.
