Phytochemical characterization and antifungal potential of leaf extracts of .

The investigation of natural alternatives to conventional fungicides is of imminent need. (Britton & P. Wilson) Bisse is a Cuban endemic plant species belonging to the Myrtaceae family. The objective of the present study was to perform a bioassay-guided fractionation to explore the potential of extracts and fractions from leaves against a panel of fungal plant pathogens. The total extract was confirmed to have good antifungal activity against (IC = 4.86 µg/mL) and moderate activity against (IC = 352.40 µg/mL) and (IC = 427.38 µg/mL) and fungicidal effect against . Five compounds belonging to the class of phloroglucinol dimers were tentatively characterized by UHPLC-HRMS and reported for the first time in and the genus Mosiera. These results suggest the potential of total extract as a natural antifungal product for the control of diseases in agriculture.
