摘要

Isoalantolactone, a major constituent of Inula racemosa (Compositae) was tested for its antimicrobial ac- tion against five bacteria, six human and six plant patho- genic fungi. The lactone showed absolute toxicities at 500 μg/mL against 3 soil borne phytopathogenic fungi (Gaeu- mannomyces graminis var. Tritici, Rhizoctonia cerealis and Phytophthora capsici) with the MICs determined to be 100, 100 and 300 μg/mL, respectively. At the MICs, isoalantoiac- tone exhibited its fungistatic nature of toxicity. The lowest fungicidal concentrations of the lactone to G. graminis var. Tritici, R. Cerealis and P. Capsici were shown to be 150, 150 And 350 μg/mL, respectively.
