For inhibition study, ricinine (10-132 ug/ml) was mixed with standard solution of substrate and the mixture (sample+standard) was injected into a stream of the phosphate buffer passed through the immobilized enzyme column and decrease in absorbance (Ai) was recorded.
population is believed to have similar trace detectible levels of ricinine in their systems.
To determinate the insecticidal and insectistatic activities of methano, hexane and ethyl acetate extracts of the seeds and leaves of Ricinus communis (Linnaeus, 1753) (Euphorbiaceae), castor oil and ricinine were tested at different concentrations against S.
