• W2928239217 abstract "To evaluate the in vitro antifungal activity of plant extracts on the growth of fungal pathogens responsible for tropical fruit rot (papaya and tomato). Methanol, dichloromethane, and water distillated of Trichilia heudelotii, Nesogordonia papaverifera, Celtis mildbraedii, Cola gigantea and Triplochiton scleroxylon were tested on strains of isolated and identified fungi from fruits of papaya and tomato. Growth inhibition tests carried out made it possible to measure their level of resistance in presence of plant extracts. Tube reactions were performed for the detection of classes of phytochemicals compounds responsible for the activity of plant extracts. Antifungal tests revealed that the extracts of all plants were fungicidal at a concentration of 10 mg / mL on fungal Colletotrichum higginsianum, Fusarium oxysporum, Rhizopus stolonifer, pathogens of papaya and tomato. Fusarium oxysporum was the most sensitive strain to methanolic and dichloromethane extracts of the organs of all plants tested. Phytochemical investigations revealed the presence of phenolic compounds, sterols and polyterpenes in the extracts of plant organs studied. The presence of these compounds may explain the antifungal activity of the extracts of these plants on all the selected strains. The use of plant extracts for the development of formulation technology of biofungicides for the control of post-harvest losses of papaya and tomato due to pathogens is proving to be a good alternative to the toxic chemicals products used for the conservation of these foods. Evaluer l’activite antifongique in vitro des extraits de plantes sur la croissance des pathogenes fongiques responsables de la pourriture des fruits tropicaux (papaye et tomate). Les extraits au methanol, dichloromethane, et a l’eau de Trichilia heudelotii, Nesogordonia papaverifera, Celtis mildbraedii, Cola gigantea et Triplochiton scleroxylon ont ete testes sur des souches de champignons isolees et identifiees des fruits de papaye et de tomate. Les tests d’inhibition realises ont permis de mesurer leur niveau de resistance. Des reactions en tubes ont ete effectuees pour la detection des classes de composes responsables de l'activite des extraits de plantes. Les tests antifongiques ont revele que les extraits de toutes les plantes ont ete fongicides a la concentration de 10 mg/mL sur les fongiques Colletotrichum higginsianum, Fusarium oxysporum, Rhizopus stolonifer, pathogenes de la papaye et de la tomate. Fusarium oxysporum a ete la plus sensible des souches aux extraits methanoliques et dichloromethanes des organes de toutes les plantes. Les investigations phytochimiques ont revele la presence de composes phenoliques et sterols et polyterpenes dans les extraits des divers organes de plantes etudiees. La presence de ces composes a permis d’expliquer l’activite antifongique des extraits de ces plantes sur l’ensemble des souches selectionnees. L’utilisation des extraits de plantes pour la formulation de biofongicide dans le controle des pertes post-recoltes dues aux agents pathogenes de la papaye et de la tomate s’avere etre une belle alternative aux produits chimiques toxiques utilises pour la conservation de ces produits." @default.
