ABSTRACT
Efficacy of three different concentrations (5, 10 and 15 mg/ml) of dry flower powder of E. splendens and L. nepetaefolia was tested on the growth of aflatoxin-producing toxigenic strains of fungi A. flavus (NCBT 101) and A. parasiticus (NCBT 128) in Sabouraud dextrose agar medium (SDA). Maximum (75%) inhibition of growth of A. flavus was seen at 15 mg/ml concentration of E. splendens flower dry powder, while A. parasiticus showed 50% inhibition of growth at 10 and 15 mg/ml concentrations. Total inhibition (100%) of growth of A. flavus was seen at 10 and 15 mg/ml for L. nepetaefolia and maximum (75%) inhibition of growth was seen for A. parasiticus at 15 mg/ml concentration. Bioassay with groundnut seeds soaked with different concentrations of flower extract proved that both fungi were incapable of infecting the seeds at 10 and 15 mg/ml of L. nepetaefolia flower extracts.
