dc.descriptionIn this study, P. divaricatum (Piperaceae) plants were subcultured by cuttings and cell tissue in order to carry out a comparison of the volatile profile, phenolic compounds, and antioxidant activity. Propagation by cuttings used vermiculite substrate and Murashige-Skoog (MS) medium in the absence of growth regulators and rooting started at 15 days of growth providing a higher number of plants after 90 days. In vitro propagation was performed using shoot apices as explants in MS media supplemented with 0.5 mg mL-1 BA (6-benzyladenine). Volatile profiles analyzed by gas chromatography-mass spectrometry (GC-MS) showed as main compounds methyl eugenol, E-?-ocimene, and ?-elemene in the in vivo and in vitro cultures. Phenolic contents determined by the Folin-Ciocalteu method had no significant difference at the end of 90 days of growth displaying a good linear correlation with antioxidant activity and phenylpropanoids amounts (r > 0.7). However, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging was higher for in vitro plants grown in comparison to in vivo plants cultured.eng
