ABSTRACT
Nanoparticles are known bio elicitors in plant biotechnology. Different concentrations of ZnO, CuO and CoO nanoparticles were used for the enhanced accumulation of secondary metabolites and antioxidant activities in the callus derived from root, shoot and leaf of Artemisia annua L. Biomass of callus was somehow affected on high concentrations of Nps. Phenolic content was observed maximum (60µg) in shoot callus at 0.1mg/l of CuONps. Total antioxidant activity was observed maximum (33µg) in root callus at 0.1mg/l of ZnOnps. Total reducing power maximum (33µg) was observed in root callus at concentration of 0.05 mg/l of CoONps. Maximum radical scavenging activity was observed in shoot callus at 0.05mg/l of ZnONps. Rutin gallic acid and caffic acid were also determined in most of the samples by HPLC. The study concludes that different Nps have positive effect on the induction of secondary metabolites in A.annua plant.
RESUMO
Nanopartículas são bio-elicitores conhecidos em biotecnologia de plantas. Diferentes concentrações de nanopartículas de ZnO, CuO e CoO foram usadas para o acúmulo aumentado de metabólitos secundários e atividades antioxidantes no calo derivado da raiz, parte aérea e folha de Artemisiaannua L. A biomassa do calo foi de alguma forma afetada em altas concentrações de Nps. O conteúdo fenólico foi observado no máximo (60 µg) no calo da parte aérea a 0,1 mg / l de CuONps. A atividade antioxidante total foi observada no máximo (33µg) no calo radicular a 0,1mg / l de ZnOnps. O poder de redução total máximo (33µg) foi observado no calo radicular na concentração de 0,05 mg / l de CoONps. Atividade máxima de eliminação de radicais foi observada no calo da parte aérea a 0,05mg / l de ZnONps. O ácido rutina-gálico e o ácido caffic também foram determinados na maioria das amostras por HPLC. O estudo conclui que diferentes Nps têm efeito positivo na indução de metabólitos secundários na planta de A.annua.
