Resumo(s)
In this work it were studied the phenolic composition of in vitro material (shoots, calli and roots) of Brassica oleracea var. costata and its antioxidant capacity. Samples were obtained in different culture medium, with distinct supplementation, in order to verify their influence in those parameters. In calli and roots no phenolic compound was identified. ln shoots it was verified the presence of thirty-six compounds, which included nine hydroxycinnamic acids, nineteen flavonoids derivatives and eight hydroxycinnamic acyl glycosides (Figure 1.). MS liquid medium supplemented with 2 mg/L benzylaminopurine (BAP) and 0.1 mg/L naphthaleneacetic acid (NAA) revealed to be the best in vitro conditions to produce shoot material with highest phenolic compounds contents and stronger antioxidant potential, thus with increased health benefits.
