Effect of auxin and cytokinin on phenolic content of Baccharis myriocephala DC. (Asteraceae) produced in vitro
A protocol for large-scale in vitro production of Baccharis myriocephala was developed. Total phenolic content was analyzed in plants cultured on MS + 1.0 mg.L-1 of indoleacetic acid (IAA), benzyladenine (BA) or kinetin (KIN). Nodal segments obtained from seeds germinated in vitro on Murashige and Skoog basal medium (MS) were subcultured on MS basal medium, hormone-free or with different growth regulators added: IAA, BA...
Development of a rich fraction in phenolic compounds with high antioxidant and antimicrobial activity in Amburana cearensis seeds extracts
Amburana cearensis is a medicinal plant widely used in folk medicine. The purpose of this study was to identify the more appropriate extraction solvent for maximum antioxidant and antimicrobial effect. The extraction of A. cearensis seeds were carried out gradually to obtain the highest yields and constituents of the extracts using as solvent hexane, methanol, 80% alcohol and water in this sequence. Phytochemical...
