Tritrichomonas foetus infects the bovine urogenital tract, causing bovine trichomoniasis. Significant economic losses may occur due to infertility and abortion among cattle. Trichomonas vaginalis is the causative agent of trichomoniasis; the most common but overlooked non-viral sexually transmitted disease worldwide. Human and bovine trichomoniasis present treatment restrictions and efforts to identify new alternatives are essential. The present study evaluated the anti-trichomonads activities of seven fractions from northwest endemic plant Manilkara rufula. Flavonoids and condensed tannins were identified from these fractions by LC-DAD-MS/MS and MALDI-MS/MS. Altogether, the results demonstrated for the first time the structural description of tannins from leaves of M. rufula and the relation of these compounds with anti-T. vaginalis and anti-T. foetus activities. Overall, this report reveals the potential of M. rufula fractions against both parasites and shows new alternatives to treat the infection caused by trichomonads.
