Description
Abstract
El objetivo fue llevar a cabo la prospección fitoquímica de la cáscara de Norantea guianensis y evaluar su potencial alelopático en la
germinación de semillas y el crecimiento inicial de plántulas de lechuga y tomate, utilizando extractos acuosos y etanólicos. Se identificaron compuestos fenólicos y sus derivados, flavonoides y taninos, así como cumarinas, antraquinonas, alcaloides y saponinas.
Se produjo interferencia negativa en la germinación y el vigor, especialmente en las semillas de tomate, y los extractos afectaron
negativamente el desarrollo de las plántulas. La especie N. guianensis tiene la capacidad de interferir en el desarrollo de otras
plantas y por esta razón, su uso debe evaluarse cuidadosamente.
The purpose of thisstudy was to carry out phytochemical prospecting of Norantea guianensis bark and to evaluate its allelopathic potential in seed germination and the initial growth of lettuce and tomato seedlings using aqueous and ethanolic extracts. We identified phenolic compounds and derivatives, flavonoids, and tannins, as well as coumarins, anthraquinones, alkaloids, and saponins. Negative interference was observed in germination and vigour tests, mainly in tomato seeds, with extracts negatively affecting seedling development. The species N. guianensis has the ability to interfere in the development of other plants, and for this reason, its use should be carefully evaluated.
