Recent emerging problem is occurrence of multiresistant pathogens. This inconvenience makes people to search for new antimicrobials. One of possible ways is looking for natural antimicrobial peptides. In our project, green tissues of tomato (Solanum lycopersicum) were chosen for isolation of such peptides. Extracts obtained were fractionated by solid phase extraction and liquid chromatography. Antimicrobial activities were tested on model microorganisms. Several fractions exhibited antimicrobial activity against bacteria and fungi. In the extracts, precursors of two antifungal proteins were identified.
