New source of quinols, the surface of Pentacalia ledifolia and Pentacalia corymbosa leaves and its antifungal activity

Julio A. Pedrozo Rubén D. Torrenegra Alba N. Téllez Alvaro Granados About the authors

Quinols identified in the surface waxes of Pentacalia ledifolia (H.B.K.) Cuatr and P. corymbosa (Benth) Cuatr. leaves, possess antifungal activity against Fusarium oxysporum and Botrytis cinerea, cultured on PDA (potato-dextrose-agar) medium. These extracts were prepared by dipping fresh leaves in chloroform for 5 min, and afforded ethyl-(1-hydroxy-4-oxocyclohexa-2,5-dien-1-yl) acetate and methyl-(1-hydroxy-4-oxocyclohexa-2,5-dien-1-yl) acetate, the major surface compounds.
