Structure, histochemistry and phytochemical profile of the bark of the sobol and aerial stem of Tontelea micrantha (Celastraceae - Hippocrateoideae)

Abstract: The bark of the underground stem of Tontelea micrantha (Mart. ex. Schult.) A. C. Sm., a native Brazilian Cerrado species, is used in folk medicine for treating kidney ailments. The structures of the underground and the aerial stems were examined and their barks were analyzed for the presence of secondary metabolites. Bark fragments were processed according to conventional techniques in plant anatomy and their chemical compositions examined using histochemical and phytochemical tests, thin layer chromatography,… Show more

“…Cells containing phenolic compounds are common in Maytenus species (Gupta & Sharma 2012) and have also been reported for other genera of Celastraceae (Mercadante-Simões et al 2014). The secondary metabolites are responsible for the relation of the plant with the biotic and abiotic environment.…”

“…Histochemical localization studies allows a quick and cost effective method for the preliminary evaluation of plant species in search of new pharmaceuticals. [36][37][38][39] The tissues of phloem parenchyma was found to be the main localising region of various phytoconstituents in G. tiliifolia bark.…”
