摘要
The effective insecticide component of natural growth Daphne genkwa Sieb.et Zucc.was extracted.The obtained material was preliminarily proved to have a favorable insecticidal effect by nonstandard insecticidal experiments,which used Chinese blister beetle.The effective component was determined as 5,4’-dihydroxy-7-methoxylflavone by UV,NMR and chemical methods.
