RESUMO
Ricinine-3,5-14C (N-methyl-3-cyano-4-methoxy-2-pyridone) administered to senescent leaves of Ricinus communis L. was translocated to all other tissues of the plant. Developing fruit and especially seeds were found to be labeled the most rapidly. Young growing leaves and other developing tissues of the plant imported ricinine from the senescent leaves much more quickly than mature leaves. Relative intensities of the radioactive ricinine imported and deposited in various tissues indicate a possible functional role of ricinine in the castor bean plant. Data on N-demethyl ricinine presented here may stimulate interest in the possible physiological role of the ricinine to N-demethyl ricinine interconversion.
