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.

Soursop (Annona muricata L.) has been used for generations by some communities in Indonesia to treat diseases. Soursop leaves are used as an alternative treatment for cancer, by boiling them in the water and consuming it. In addition to the treatment of cancer, soursop plant is also used for the treatment of skin diseases such as boils. This study aimed to determine the antibacterial activity of ethanol extract of soursop leaves of young and old against Staphylococcus aureus, determine the content of secondary metabolites, and find out the diameter of inhibitory young leaves and old leaves of soursop in inhibiting Staphylococcus aureus. Soursop leaves were extracted by maceration using ethanol 96%. The extract obtained was then carried out to phytochemical screening. Antibacterial activity test was conducted using disc the Kirby-Bauerdiffusion. This study used 6 concentrations of 500 mg/mL, 400 mg/mL, 300 mg/mL, 200 mg/mL, 100 mg/mL, 80 mg/mL, 60 mg/mL, 40 mg/mL, 20 mg/mL, 10 mg/mL and 1 mg/mL. A positive control used soursop leaf extract of young and old while a negative one used DMSO 10%. Based on phytochemical screening, ethanol extract of soursop leaves contained alkaloids, flavonoids, saponins, tannins, steroids/triterpenoids and glycosides. The antibacterial activity of ethanol extract of leaves of young soursop was higher in inhibitory diameter than the ethanol extract of old soursop leaves. It could be seen that a concentration of 500 mg/mL was equal to 10.87 mm and 8.68 mm; a concentration of 400 mg/mL was equal to 9.15 mm and 7.3 mm; a concentration of 300 mg/mL was equal to 8.34 mm and 6.30 mm; a concentration of 200 mg/mL was equal to 8.23 mm and 7.08 mm; a concentration of 100 mg/mL was equal to 6.32 mm and 6.18 mm, and a concentration of 80 mg/mL did not leave a diameter inhibitory to bacteria Staphylococcus aureus. Young soursop leaf ethanol extract was more effective than the old soursop one against Staphylococcus aureus.

Bacteria are important agents in causing infectious diseases. Indonesian people often use antibiotics along with herbal medicines. Cecendet (Physalis angulata L.) is one of the traditional plants that have antibacterial activity and widely used by the Indonesian community. This study aims to test the antibacterial activity of cecendet herbs and their effects when used in combination with various antibiotics. The preparation of P.angulata extract was carried out using reflux method with ethanol 50%. The characteristic examination and phytochemical screening are examined on simplicia and the extract. Determination of antibacterial activity from P.angulata extract was done by microdilution test method by assessing minimum inhibitory concentration (MIC). Determination of the effectiveness of combination of antibiotics with herbal cecendet against test microbes Staphylococcus aureus and Klebsiella pneumoniae was done by using checkerboard method. The results of phytochemical screening showed that simplicia and P.angulata extract contained alkaloids, flavonoids, saponins, polyphenols, monoterpenoids, sesquiterpenes, steroids and triterpenoids. The result of antibacterial activity test showed that P.angulata extract had antibacterial activity against S.aureus and K.pneumoniae with the MIC was 128 μg/mL, 256 μg/mL. The synergistic interaction of S.aureus is demonstrated by the combination of P.angulata herb extract with tetracycline. The additive/indifferent interaction of S.aureus is demonstrated by the combination of P.angulata extracts with ampicillin, and against K.pneumoniae shown by the combination of P.angulata extract of cecendet with ampicillin or tetracycline. Ethanol extract of P.angulata has antibacterial activity and and combination with antibiotics (ampicillin/tetracyclin) can give synergistic effect or additive of S.aureus and K.pneumoniae bacteria.</em></p><p align="center"><strong><em> </em></strong></p><p><strong><em>Keywords</em></strong><em>:  Cecendet, Physalis angulata L., MIC, antibiotic combination</em></p>

Various strategies have been employed in the treatment and management of Salmonella infection however, Salmonella strains have gained resistance to antibiotics. This study was to determine in vitro anti-Salmonella activity of Boerhaavia diffusa leaf extract against clinical isolate of Salmonella typhi and Salmonella typhi ATCC 14028. The aqueous and ethanol extracts of B. diffusa were studied for their antibacterial activity against pathogenic Salmonella typhi. This study was carried out between April and September 2018. The in vitro antibacterial activity was performed by agar well diffusion method and broth dilution using spectrophotometric method and the results were expressed as the average diameter of zone of inhibition of bacterial growth around the well and optical density respectively. It was observed that aqueous extract exerted slightly higher activity than ethanolic extract as revealed by the mean diameter of zone of inhibitions at a concentration of 200 mg/ml, the aqueous extract had 35.21±0.47 mm (Salmonella typhi ATCC 14028) compared with ethanol extract 26.41±0.32 mm (clinical). However, in the broth dilution method, ethanol extract significantly (p=0.05) reduced the cell, at 48 hours, the optical density of clinical isolate of S. typhi treated at concentration of 200 mg/ml of extract was 0.47±0.02 nm while at the same concentration of extract, aqueous extract had an optical density of 0.52±0.11 nm respectively. The phytochemical assay revealed that tannin (5.18±0.02 mg/g) and quinone (8.45±0.13 mg/g) in ethanol extract was significantly (p=0.05) higher than aqueous extract while saponin (14.18±0.06 mg/g) was higher in the aqueous extract. The ethanol and aqueous extracts of leaves of B. diffusa whole plant exhibited significant antibacterial activity against both clinical and typed Salmonella typhi. Therefore, the plant extract could be used for the treatment of Salmonellosis, however, the in vivo studies is needed to ascertain the safety of the extract.
