Morphoanatomical characterization and chemical study of the internal portion of the stem bark of Sambucus australis Cham. & Schltdl

Abstract

ABSTRACT The internal part of the stem bark of this species is used to produce a homemade ointment in some regions of the state of Rio Grande do Sul. The purpose of this study is to characterize the morphoanatomy and identify the compounds present in the internal part of the stem bark of S. australis through chemical and histochemical methods. In addition, the best extraction conditions for the sample were determined. It was possible to quantify the rutin and total phenolic compounds, as well as define the Soxhlet method with an 80% hydroethanolic solution as the best method for extracting these compounds from the bark of the species. The portion of the stem bark that is popularly used could also be determined. Based on the results, new studies will be performed in order to identify other characteristics of the species and the possible reasons that sustain its traditional use.
