Chemical composition and antifungal activity of Piper auritum Kunth and Piper holtonii C. DC. against phytopathogenic fungi

The growth of fungi during pre - and postharvest of fruits may cause spoilage and result in a reduction in quality and quantity. The aim of the present work was to investigate the efficacy of four extracts (n-hexane, dichlorometane, ethyl acetate, and methanol) and the essential oil of Piper auritum...
