Atividades antioxidante e antifúngica dos óleos essenciais de Cochlospermum regium frente à Sclerotinia sclerotiorum e Colletotrichum gloeosporioides

Abstract

The objective of this work was to evaluate the essential oils of Cochlospermum regium and its antioxidant and antifungal activities against Sclerotinia sclerotiorum and Colletotrichum gloeosporioides. Roots and leaves were collected in individuals of C. regium in a Cerrado area, the material was processed, weighed and extraction of the oils were by the hydroventilation method in Clevenger. The oils had their evaluated yield, as well as the antioxidant and antifungal activities against S. sclerotiorum and C. gloeosporioides. Yields were 0.168 and 0.301% for leaves and roots; the antioxidant activity showed 100% reduction of the DPPH radical was 100% in the concentrations between 50 and 30 μL mL-1 and the mycelial inhibition of 14.2 and 60.1% in the concentration of 100 μL mL-1 for S. sclerotiorum and 84.4 and 81.3% for C. gloeosporioides for root and leaf oils, respectively.
