  • Applications

    Maysin is a flavone glycoside found in maize silks and is primarily of interest as a natural insect-deterrent and as a component or target in crop-protection strategies. In agriculture, it may be used in seed coatings or foliar formulations to enhance resistance to chewing pests and to support integrated pest management. In biopesticide development, it is considered as a botanical bioactive ingredient or a lead scaffold for the discovery of new insecticidal agents. In crop-protection research, maysin is studied to understand maize defense pathways and resistance traits, guiding breeding programs. In analytical and phytochemical research, maysin serves as a reference compound for method development and metabolite profiling in maize extracts.
