Introduction: Corn silk or known as herb name stigma maydis is an important medicinal botanical in many traditional medicines worldwide, including jamu, an Indonesia traditional medicine. The exploration of corn silk to treat acne vulgaris is still lacking, therefore the current research was conducted to analyze the activity of ethanolic extract from corn silk (EECS) against 3 acne-related bacteria, Propionibacterium acnes, Staphylococcus epidermidis and Staphylococcus aureus. Materials and Methods: The antibacterial activity of EECS at concentration range of 10 to 100% v/v was evaluated using the disk diffusion method. As comparation, distilled water was used as a solvent control, while 1% clindamycin was used as a positive control. Results: Shinoda’s test showed that flavonoid was detected in the EECS. The higher concentration of EECS exhibited higher diameter of inhibition zone indicating higher antibacterial activity on P. acnes, while the antibacterial activity of S. epidermidis was not increased at similar concentrations of EECS. The antibacterial activity of EECS against S. aureus decreased at the higher EECS concentration (>70%). Conclusion: Taken together, EECS is a potential as a bioactive source to inhibit the growth of acne-related bacteria P. acne, S. epidermidis and S. aureus. Further investigation is needed to explore the corn silk or stigma maydis as a medicinal botanical in jamu targeted to treat acne vulgaris.

Abstract. Nugroho LH, Dewatisari WF, Retnaningrum E, Purwestri YA. 2021. The potency of Sansevieria trifasciata and S. cylindrica leaves extracts as an antibacterial against Pseudomonas aeruginosa. Biodiversitas 22: 408-415. Sansevieria trifasciata and Sansevieria cylindrica are the major herbs in Indonesia, which contain several bioactive compounds as potential sources of antibacterial agents. This study aims to evaluate the antibacterial activity of S. trifasciata and S. cylindrica leaves extract and fraction against Pseudomonas aeruginosa and to identify its bioactive compounds. Crude ethanolic extract of S. trifasciata and S. cylindrica leaves were tested for their antimicrobial activity by disk diffusion method against P. aeruginosa. S. trifasciata showed strong antibacterial activity with an inhibition zone of 18.3 mm compared to S. cylindrica. Different concentrations of extract i.e. 4 mg/mL, 8 mg/mL, 16 mg/mL, 32 mg/mL, 64 mg/mL, 128 mg/mL and 256 mg/mL were tested for their minimum inhibitory concentrations (MIC). The MIC results showed that the S. trifasciata extract was able to inhibit bacterial growth at a concentration of 32 mg/mL. Results of vacuum liquid chromatography (VLC) and thin-layer chromatography (TLC) revealed that only fraction 3 showed the highest antibacterial activity at 16 mg/mL. In TLC bioautography analysis, fraction 3 showed a clear zone at Rf 0.93. The phytochemical analysis showed that terpenoid, phenolic, triterpenoid, and flavonoid compounds were found in S. trifasciata extract that were associated with antibacterial activity.

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.

The leaves of kenikir are known to have many benefits, one of which can be used as medicine. Kenikir leaves are reported to have antibacterial activity against the bacteria Salmonella typhi (S.typhi). S. typhi is a bacterium that causes typhoid fever. Typhoid fever is still an endemic disease in Asian countries, especially Indonesia. Typhoid fever became the third largest disease in Indonesia in 2010. The study related to the antibacterial activity of kenikir leaf fraction to S. typhi has never been reported. Therefore, it is necessary to conduct research related to the antibacterial activity of extracts and leaf fractions of kenikir to compare their potential against S. typhi. The study was conducted using the disk diffusion method using 5 series of concentrations namely 5%, 10%, 15%, 20%, and 30%. Tests were carried out on methanol extract, hexane, ethyl acetate, and methanol-water fraction. The results showed that highest inhibition zone diameter is 7,75 mm which is reached by methanol extract. The order of the highest inhibiting zone diameter are extract, hexane, ethyl acetate, and methanol-water fraction.

Genus Mentha presents group of plants which are the most studied in family Lamiaceae. Aboveground parts are used for different purposes in pharmacy, food industry or confectionery. Most important is natural product extracted from leaves - essential oil (EO). The aim of presented experiment was to demonstrate different chemotype and compare antibacterial activity of two Mentha species EO. Plant samples were obtained from various environments – from Slovakia and from Italy. Dominant compounds were determined by GC/MS. The results showed high amount of menthol and menthone in tested Slovak peppermint EO. On the other hand, carvone and 1,8-cineole were determinate as dominant compounds in Italian spearmint EO. The antimicrobial activity of the EO was investigated by disc diffusion and broth micro dilution methods. EO was evaluated for their antibacterial activity against 7 microorganisms: Enterobacter cloacae, Salmonella spp., Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, Streptococcus pyogenes. The determination results of antibacterial activity by agar disk diffusion method ranged from 7 to 14 mm of the growth inhibition zone. MIC of tested mint EO varied from 0.625 to 2.5 μg/mL. In addition, both EO showed relatively the same antibacterial activity against the selected Gram-negative bacteria. However, there is a variation in the antibacterial activity against Gram-positive bacteria.

Endophytes or endophytic fungi have been investigated as a store house of bioactive compound. This study was aimed to evaluate the potential antibacterial activity of endophytic fungi isolated from Medinilla speciosa Blume. The antibacterial test was determined by measuring the inhibition zone with disk-diffusion method. Twenty endophytes were isolated from the leaves of Medinilla speciosa Blume and identified morphologically. The results demonstrated that ten isolates showed variation in their antibacterial activity against Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, Bacillus subtilis ATCC 6633, and Shigella dysenteriae ATCC 13313. Further investigation will be needed to explore and identify the bioactive molecules of the isolated endophytic fungi.
