PHENANTHROINDOLIZIDINE ALKALOID QUATERNARY AMMONIUM SALT DERIVATIVES, AND PREPARATION THEREOF AND APPLICATION THEREOF IN RESISTANCE TO PLANT VIRUSES

摘要

The present invention relates to phenanthroindolizidine alkaloid quaternary ammonium salt derivatives, and preparation thereof and application thereof in resistance to plant viruses. The structure of the phenanthroindolizidine alkaloid quaternary ammonium salt derivatives is represented by a general formula (I). The phenanthroindolizidine alkaloid quaternary ammonium salt derivatives have good light stability, heat stability and water solubility, exhibit excellent plant virus resistance activity, and can well inhibit tobacco mosaic virus.
