The fruit of Cyrtocarpa procera is used to treat stomach diseases by people living in San Rafael, Coxcatlan, Puebla. This work investigated the antibacterial, antioxidant, cytotoxic and anti-inflammatory activities of the fruit produced by this species. Methanol extract was obtained by maceration. After obtaining the methanol extract (MeOH1), methanol subextract (MeOH2) and hexane (H) were obtained. The antibacterial activities of MeOH1, MeOH2 and H were evaluated through disc-diffusion. The quenching of free radicals was evaluated by decolorizing a methanolic DPPH solution. The cytotoxic activity of MeOH2 was evaluated by in vitro assay system of growth inhibition of human cervical carcinoma cell line (CasKi). The IL-1β and TNF-α were determined through ELISA in the supernatants of the macrophage cell line (RAW 264.7). The MeOH2 subextract was separated by column chromatography, seventy-three fractions were collected. The Gram-positive and -negative bacteria examined were sensitive to MeOH1 and MeOH2; the MeOH2 was bactericidal toward Staphyloccocus aureus (MIC = 4 mg/mL) and Vibrio cholera (MIC = 4 mg/mL). The MeOH2 inhibited the DPPH radical (SC50 = 69.7 μg/mL), but a cytotoxicity assay revealed that the extract is not toxic according to the National Cancer Institute (LD50 = 22.03 μg/mL). The production of proinflammatory cytokines (IL- 1β and TNF- α) by LPS- stimulated macrophages was reduced after the treatments. The methanol extract contained various organic acids, such as citric acid, palmitic acid and α- linoleic acid. The fruits of Cyrtocarpa procera are employed to treat ailments such as diarrhea, in this study were demonstrated some biological activities involved in a bacterial infection. This is the first research about of the medicinal properties of C. procera fruit.
