Polygala paniculata: um recurso de salicilato de metila produzido por cultura de tecidos vegetais

Abstract: RESUMOPolygala paniculata: um recurso de salicilato de metila produzido por cultura de tecidos vegetais O estabelecimento de cultura in vitro de Polygala paniculata L. permitiu a propagação rápida de matéria-prima vegetal sob condições assépticas e padronizadas. As plantas in vitro foram submetidas à extração e destilação simultâneas (EDS) e a composição química do óleo essencial foi analisada por CG/DIC e CG/EM. Foram avaliados os efeitos de BAP (6-benzilaminopurina) sobre o desenvolvimento in vitro e produçã… Show more

“…Figure 1 shows the spectrograms of the microcapsules that were obtained, as well as those of the wall materials, gelatin and gum Arabic and of the active ingredient methyl salicylate. Methyl salicylate has in its molecule intramolecular hydrogen bonds between hydroxyl and carbonyl groups [20]. The bands in the regions of 3175 cm −1 and 2952 cm −1 are attributed to the hydroxyl group and the asymmetrical stretching of the CH2, respectively.…”

“…The gum Arabic has in its chemical structure carboxylic groups, which justifies the presence of negative charges. The bands at 1603 cm −1 and 1421 cm −1 are derived from the asymmetric and symmetric stretching vibration of carboxylic acid (−COO ), respectively, which is attributed to the Methyl salicylate has in its molecule intramolecular hydrogen bonds between hydroxyl and carbonyl groups [20]. The bands in the regions of 3175 cm −1 and 2952 cm −1 are attributed to the hydroxyl group and the asymmetrical stretching of the CH 2 , respectively.…”

“…In addition, co-cultivation of nodal segments of S. oleracea and Polygala paniculata L. was performed. P. paniculata L. in vitro culture demonstrated production and release of methyl salicylate according to Victorio et al (2011). The cultures were maintained in a growth chamber under cool-white fluorescent lighting tubes (1.6 W m -2 , 23 µmol.m -2 s -1 and daily photoperiod of 16 h at 25 ± 2°C).…”
