ABSTRACT The present study aimed to evaluate the effect of the acetone extract of the leaves of Momordica charantia L. on Cutibacterium acnes. For this purpose, the previously prepared acetone extract was solubilized in 1% dimethylsulfoxide at a concentration of 2000 µg/mL and and diluted to a concentration of 3.91μg/mL. The strain Cutibacterium acnes ATCC 6919 was seeded on tryptic soy agar (TSA) plates supplemented with 5% sheep's blood. It was incubated at 37 °C and then transferred to Brain Heart Broth (BHI) broth supplemented with 1% dextrose. Using the McFarland 0.5 scale, bacterial inocula were standardized and 100 μL of culture broth (20 μL of extract and 80 μL of inoculum) was added. Doxycycline was the positive control at concentrations of 8 μg/mL to 0.015 μg/mL. The microplates were incubated for 24 h at 37°C and 10 μL of resazurin (0,01%) was added and allowed to incubate at 37°C for 2 h. The blue coloration was interpreted as absence of bacterial growth and the pink coloration as growth. The minimum inhibitory concentration (MIC) was determined to be 500 ug/mL and through UPLC-MS analysis, the major components were found to be Mormordicina IV and Kuguacina S.
