Micropropagação de Salvia officinalis L. com avaliação do teor de fenóis totais e atividade antioxidante

Stem cuts and seeds of Salvia officinalis were incubated on nutrient media for plantlets production and analysis of the total phenolic compounds, total flanovoids and antioxidant activity in micropropagated plants. Explants were obtained from seedlings and inoculated on MS with different concentrations of benzylaminopurine (BAP) and indolbutyric acid (IBA). After 30 and 60 days of incubation, the explants were scored for percentage of contaminated, dead and oxidized explants and mean bud numbers. For bud formation, the most efficient treatment was the medium containing BAP at 1 mg L-1, for the plantlet height the better medium was the control without the addition of plant regulator. IBA promoted the formation of few roots. Our results indicated that stem cuts incubated on media containing BAP and/or IBA did not increase the total flavonoid contents, but increased the total phenolics' by BAP and high antioxidant activity by 1 mg L-1 BAP.
