The aim of the study was to evaluate the in vitro propagation ability of 10 clonal lines of thorny globe artichoke (Cynara scolymus L.). The study methodology comprised five stages of evaluation. The stages evaluated were initiation, multiplication, rooting, acclimatization, and transplant to the field. The study began with the initiation of dissected shoot tips of 10 clonal lines in test tubes containing the Murashige and Skoog (MS) medium. Best results were obtained when explants were cultured on an induction medium containing MS + naphthalene acetic acid (NAA) 1.0 mg l−1 + benzyl aminopurine (BA) 1.0 mg l−1, highlighting clonal lines L-250, L-132, and L-62. Because of high rates of vitrification and phenolization in the initial stage, clonal lines L-24, L-127, and L-142 were discarded from the study. Therefore, only seven clonal lines were included for evaluation in the multiplica...

The properties of Annona muricata L. (guanabana) have been demonstrated in studies carried out on the its leaves, pulp, seeds, stems and fruit peel; highlighting in each of them its antioxidant properties. In the present work the quantification of the total polyphenols and the evaluation of the antioxidant capacity in the ethanolic extract of the flowers of Annona muricata L. (guanabana) was carried out. The flowers samples were collected in the province of Jaen (Cajamarca, Peru). The ethanolic extract was obtained by maceration of the pulverized dried flowers. The quantification of the polyphenols in the ethanolic extract of the flowers was carried out using the Folin-Ciocalteu technique using gallic acid as a pattern. The evaluation of the antioxidant capacity was carried out using the methods of capturing the radical’s DPPH and ABTS. + using the Trolox as a pattern for both methods....
