Benzylglucosinolate was detected in all of the tissues of Carica papaya (pawpaw). No other glucosinolates were detected in any tissue of C. papaya. Previous suggestions that indolyl-3-methylglucosinolate might be present could not be confirmed. The highest concentrations of benzylglucosinolate were found in the youngest leaves; but the compound was also detected in leaf stalks; stem internodes and roots. The presence of benzylglucosinolate in shoots was developmentally regulated?high concentrations in young tissues; declining as they matured (Bennet et al. 1997)
