Phytochemical composition and antioxidant activity in brassica oleracea var. Sabellica under the effect of plant growth regulators

Abstract

© 2019 Almughraby et al. The aim of this study is to investigate the effect of natural hormones (gibberellic acid, brassinolide) and Commercial preparations of growth stimulants (ecopain, novosil) on the content of carotenoids, ascorbate, phenols, flavonoids, as well as antioxidant activity in kale Brassica oleracea var. Sabellica. Our results demonstrated the possibility of controlling the phytochemical composition of kale through treatment with growth regulators - natural phytohormones and commercial preparations. All the studied compounds increased the content of health-promoting compounds and the antioxidant activity of kale cabbage, but in different degrees. The content of carotenoids was largely influenced by gibberellic acid, ascorbate and flavonoids by brassinolide. While novosil had the greatest effect on increased antioxidant activity.
