Propriétés physico-chimiques et antifongiques des extraits de deux plantes thérapeutiques : L’Ortie (Urtica dioïca .L) et Fougère - Aigle (Ptéridium aquilinum .L) contre le Fusarium oxysporum f .sp. lycopersici

Abstract

The objective of this study is to know the physico-chemical properties of the extracts of two medicinal species: Ortie (Urtica dioïca) and Fougère – Aigle (Ptéridium aquilinum). The quantitative analysis yielded polyphénols T (0,054. 0,202), flavonoїds (1,732. 4,257), tannins C (3,308. 2,283) and saponine contents. The antifungal activity of the extracts prepared with different methods showed an efficacy by reducing the diameter of growth of the fungus Fusarium oxysporum f.sp.lycopersici. Geant visa when can use it as biopesticides and its application field tests.
