Antifungal activity of new compounds from Nepeta leucophylla and Nepeta clarkei

Abstract

Iridodial β-monoenol acetate, isolated from the essential oil of Nepeta leucophylla Benth, and actinidine from N. clarkei Benth were screened for antifungal activities against Aspergillus flavus, Aspergillus ochraceus, Penicillium citrinum, and Penicillium viridicatum, all known mycotoxin- producing taxa, and Sclerotium rolfsii and Macrophomina phaseolina, potential soybean pathogens. Iridodial β-monoenol acetate was most effective against S. rolfsii, while actinidine was highly active against M. phaseolina.
