Bacterial antimicrobial resistance is a major health problem worldwide. Plants consumed by non-human primates are potentially safe for humans. In this study, we examined the potential antibacterial properties of plants consumed by non-human primates in Indonesia. We studied the antibacterial properties of the leaf extracts of 34 primate-consumed plants against Escherichia coli and Bacillus subtilis in vitro. The plants were collected from the Pangandaran Conservation Area, West Java Province, Indonesia. The leaves were dried and then powdered by crushing and the potential active ingredients were extracted with 95% ethanol at room temperature for 24 hours. The obtained solvent was then dried at 50 degrees C under reduced pressure. The antibacterial properties of each product were then tested to determine the minimum inhibitory and minimum bactericidal concentrations using the broth microdilution technique and a disc diffusion test was also performed. The results show Kleinhoviahospita, Dillenia excelsa and Garcinia celebica had the best antibacterial properties against Escherichia coli and Ficus benjamina, Ficus altissima, and Elaeocarpus glaber had the best antibacterial properties against Bacillus subtilis. Some of the studied leaf extracts in our study have the potential to be developed into antibacterial medications and need to be studied further.
