Abstract
Crop protection against pests and diseases remains a critical challenge for sustainable agricultural production, particularly in tropical regions. This study investigated the phytochemical composition and antioxidant properties of leaf extracts from Carica papaya and Urtica dioica cultivated in Côte d'Ivoire, aiming to assess their potential as natural biopesticides. Phytochemical screening revealed the presence of polyphenols, flavonoids, tannins, alkaloids, sterols, and polyterpenes in both species. Quantitative analyses showed significantly high contents of total polyphenols (158.8 to 176.9 mg GAE/g dry matter) and flavonoids (152.7 to 153.8 mg QE/g dry matter). Antioxidant activities evaluated by DPPH and ABTS assays highlighted strong free radical scavenging capacity, especially in Urtica dioica extracts. The bioactive secondary metabolites identified are known for their antimicrobial, antifungal, and insecticidal effects, supporting their application in integrated pest management. These findings underscore the potential of Carica papaya and Urtica dioica leaf extracts as eco-friendly, low-cost biopesticides to reduce reliance on synthetic chemicals and promote sustainable crop protection in Côte d'Ivoire.
