In this study, possible alternatives for the valorization of dwarf pomegranate fruits have been explored. The characterization of their hydromethanolic extract by gas chromatography−mass spectrometry evidenced the presence of high contents of 5-hydroxymethylfurfural (a carbon-neutral feedstock for the production of fuels and other chemicals) and β- and γ-sitosterol stereoisomers. The microbicidal activity of the crude extract, both alone and in a conjugate complex with chitosan oligomers (COS), was investigated against three plant pathogenic microorganisms that cause significant losses in woody crops: Erwinia amylovora, E. vitivora, and Diplodia seriata. In in vitro assays, a strong synergistic behavior was found after conjugation of the bioactive constituents of the fruit extract with COS, resulting in minimum inhibitory concentration (MIC) values of 750 and 375 μg·mL−1 against E. amylovora and E. vitivora, respectively, and an EC90 value of 993 μg·mL−1 against D. seriata. Hence, extracts from the non-edible fruits of this Punicaceae may hold promise as a source of high value-added phytochemicals or as environmentally friendly agrochemicals. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2022 The Authors Atribución 4.0 Internacional Pomegranate Plants Granado Infrared spectroscopy Espectroscopia de infrarrojos Gas chromatography Cromatografía de gases Mass spectrometry Espectrometría de masas 5-hydroxymethylfurfural Phytochemicals Microorganismos fitopatógenos Plants, Protection of Plantas - Protección Analytical chemistry Dwarf pomegranate (Punica granatum L. var. nana): Source of 5-HMF and bioactive compounds with applications in the protection of woody crops info:eu-repo/semantics/article
