| Abstract: | High performance liquid chromatographic (HPLC) analysis of mycelia of Sclerotium rolfsii grown on neem cake, and Zephyarenthes citrina bulb incorporated media was carried out. Several phenoloic acids, e.g., gallic, tannic, caffeic, cinnamic, chlorogenic and O-coumeric acids, were found in considerable amounts in treated mycelial mat as compared to the control. The amount of phenloic acids increased with increased concentration of both the materials in mycelia of 7 and 14 day-old cultures. Due to anti-oxidant and several other properties of phenolic acids, the senescence of the fungus has been prolonged which may be one probable reason of sustaining the virulence of the pathogen. |
