| Title : | VALORIZATION OF ESSENTIAL OIL EXTRACTION BY-PRODUCTS FROM TWO MEDICINAL AND AROMATIC PLANTS FOR ANTIFUNGAL ACTIVITY |
| Abstract : | Traditional chemical fungicides remain widely used for disease control; however, concerns about environmental contamination, residue persistence, and pathogen resistance have intensified the search for sustainable alternatives. Plant-derived extracts, particularly from aromatic species, represent promising biopesticides due to their richness in bioactive metabolites, diverse antifungal mechanisms, and favorable ecological profiles. This study investigates the antifungal potential of aqueous plant extracts derived from essential oil extraction waste of Artemisia sp. and Cymbopogon citratus against Pythium Ultitum. After hydro-distillation of the powdered plant materials to extract essential oils, the residual biomass was reused to prepare aqueous extracts via maceration. Five concentrations (1%, 2%, 5%, 10%, and 20%) of each extract were evaluated using the poisoned food technique. Mycelial growth inhibition was significantly affected by extract concentration (P < 0.001). The highest inhibition was observed at 20%, reaching 100% for C. citratus and 76.42% for Artemisia sp. extracts. In contrast, the lowest inhibition was recorded at 1%, with values of 34.96 % for C. citratus and 28.21% for Artemisia sp.. On the other hand, the determination of flavonoids and total phenol contents was performed using the spectrophotometric methods with aluminum chloride (AlCl3) and the Folin-Ciocalteu, respectively. Phytochemical analyses revealed that C. citratus extract contained higher flavonoid levels (10.59µg QE/mg dry extract) compared to Artemisia (6.97µg QE/mg). However, total phenolic content was greater in Artemisia (92.28µg GAE/mg) than in C. citratus (67.50µg GAE/mg). These findings suggest that post-distillation plant residues retain significant antifungal activity and bioactive compound content, supporting their valorization as potential active ingredients in biopesticide formulations for the management of P. ultitum. |
