Insecticidal Property of Flavinoid Isolated from Tephrosia PurpuriaAuthor(s): R. K. Diwan and R. C. Saxena
Flavinoid glycosides fraction FR-1 and FR-2 were isolated from Tephrosia purpuria. These were used in five different concentrations. They showed more than 90 mortality within 24 hr. period to Callosobruchus maculatus grubs, which feeds upon Phaseolus mungo .The plant used in the present study is of medicinal value, which has yielded some toxic ingredients as insecticidal compound.
