| description | Background and Aims: The phytochemistry study of Annonaceae has intensified in the last decades due to the discovery of secondary metabolites with antimicrobial activities. The inhibitory activities of extracts and compounds from these species for phytopathogens are less known. The antifungal activity of Sapranthus microcarpus was determined in vitro against six fungal pathogens of important crops.Methods: Hexane, methanol, and alkaloid extracts of the leaves and root and stem bark of S. microcarpus were evaluated to determine whether they could inhibit the mycelial growth of the phytopathogens. The combined activity of the most active extracts for each phytopathogen was also determined. The alkaloid liriodenine was isolated and identified as an antifungal principle.Key results: All extracts inhibited the growth of the six phytopathogens to some extent. The root bark alkaloid extract showed the highest activity. Fusarium oxysporum f. sp. lycopersici and Curvularia lunata were the most sensitive phytopathogens. Liriodenine was active against all the plant pathogens (minimum inhibitory concentrations of 125-500 nmol ml-1).Conclusions: Sapranthus microcarpus is a native natural resource with great phytochemical potential. |

Antecedentes y Objetivos: El estudio de la fitoquímica de Annonaceae se ha intensificado en las últimas décadas debido al descubrimiento de metabolitos secundarios con actividades antimicrobianas. Las actividades inhibidoras de extractos y compuestos de estas especies para fitopatógenos son menos conocidas. Se determinó la actividad antifúngica in vitro de Sapranthus microcarpus contra seis hongos fitopatógenos de cultivos importantes.Métodos: Se evaluaron extractos metanólicos, hexánicos y alcaloidales de las hojas, y corteza de tallos y raíces de S. microcarpus por el método de inhibición micelial. También se determinó la actividad combinada de los extractos más potentes contra cada fitopatógeno. Se aisló e identificó al alcaloide liriodenina como uno de los metabolitos antifúngicos.Resultados clave: Todos los extractos, en alguna medida, inhibieron el crecimiento de los seis fitopatógenos. Los extractos alcaloidales mostraron la mayor actividad. Fusarium oxysporum f. sp. lycopersici y Curvularia lunata fueron los fitopatógenos más sensibles. Liriodenina fue activo contra todos los fitopatógenos (a concentraciones inhibitorias mínimas de 125-500 nmol ml-1).Conclusiones: Sapranthus microcarpus es un recurso nativo con alto potencial fitoquímico.
