Abstract

In this study, the nitrogen and carbon sources, light conditions and higher temperature was applied to batch cultures of Astragalus trojanus Stev. Callus obtained in semi-solid WPM medium supplemented with 1 mg/L 6-benzyladenine and 100 μg/L selenium were transferred to liquid medium with the same composition under dark conditions. In order to investigate the effects of medium composition and culture conditions on biomass, astragaloside IV and cycloastragenol accumulations, 505 mg/L KNO3, 16 g/L glucose, light conditions (1000 lux) and 28°C temperature were implemented to cell cultures. Biomass did not ascend, however, accumulation of astragaloside IV (AST IV) and cycloastragenol (CG) was affected. The highest AST IV (0.3018 μg/mg) and CG (13.160 μg/mg) concentrations were detected in light conditions and KNO3 added medium, respectively. Addition of KNO3 instead of NH4NO3 increased cycloastragenol accumulation, but astragaloside IV decreased. At 28°C, neither of the components can be detected.

Abstract

The insect Callosobruchus maculatus, is responsible for serious damages in the storage of grains of diverse cultures, among them, the one of the beans. Therefore the development of substances capable of being an alternative to minimize agricultural losses and thus contribute to food security of the population is a current necessity. Thus, the objective of this work was to perform the synthesis of ibuprofen derivatives and to evaluate their effect on mortality of common bean weevil. toxicity tests of the derivatives were carried out with the Callosobruchus maculatus weevil through direct contact for 48h.The synthesis of the derivatives presented good yields (65 to 95%) and it was possible to perceive that they have a bioactive effect against C. maculatus, with a mortality rate of up to 100% after 24 hours of applicationusing a concentration of 1 mg/mlof each derivative in separate experiments.With this it is possible to emphasize that the derivatives produced and evaluated can be promising as pest control agents.
