Passiflora species have high industrial and medicinal relevance, due to presence of specific metabolites and their recognized pharmacol. activities. In vitro systems allow the modulation of secondary metabolites production according to culture conditions. In this work, we report the effect of different light emitting diodes (LED) on induction, metabolite production, and antioxidant properties of calluses derived from stem and leaf segments of P. setacea cv BRS Peŕola do Cerrado. Friable calluses were induced on MSM medium supplemented with picloram, under different light qualities (white fluorescent lamps or different types of LEDs) or in the dark. Light quality contributed more significantly for biomass accumulation than the other variables. Callus formation was observed in response to all treatments, although the highest biomass accumulation was induced by red LED. Chromatog. analyses indicated that blue LED induced the highest production of bioactive substances. All samples displayed low antioxidant potential by the DPPH assay, but showed a high capacity to chelate iron. The activity of antioxidant enzymes was also evaluated. The incubation under red LED caused an increase on the activity of superoxide dismutase, catalase and ascorbate peroxidase in calluses derived from internodal segments induced under red LED. This is the first study evaluating the effect of lighting conditions in in vitro systems of P. setacea cv BRS Peŕola do Cerrado, thus opening new possibilities of study and utilization. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Recommanded Product: Methyl nonadecanoate).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Recommanded Product: Methyl nonadecanoate
