DIAS, E.G.E. et al. Quality and authenticity of leaves of "chapéu-de-couro" (Echinodorus grandiflorus) from suppliers in São Paulo. Rev. bras. plantas med. [online]. 2013, vol.15, n.2, pp.250-256. ISSN 1516-0572.

Echinodorus grandiflorus and Echinodorus macrophyllus, known as "chapéu-de-couro", have been differently used as anti-inflammatory agents. The aim of the present study was to carry out physicochemical analyses of three leaf samples (A, B and C) from "chapéu-de-couro" (E. grandiflorus) obtained from suppliers in São Paulo to assess the quality and the authenticity of these samples according to the Brazilian Pharmacopoeia (BP) 5th edition. All samples were in agreement with the specifications of the Pharmacopoeia considering their organoleptic characteristics, foreign material, humidity, total ash and sulfated ash (except for samples A and B), as well as the levels of o-hydroxycinnamic acid derivatives (except for sample A). Macroscopic and microscopic analysis of the samples revealed structures typical of E. grandiflorus. Analysis of chromatographic profiles by thin-layer chromatography (TLC) on silica gel indicated the presence caffeic acid, isoorientin and swertiajaponin, which are in accordance with the monography for this species. Sample C was the only plant drug approved according to the criteria of the Brazilian Pharmacopoeia, evidencing the need of quality control of raw plant material to ensure the production of safe and effective phytomedicines.

Keywords : Echinodorus grandiflorus; authenticity; chromatographic profile; morphological markers.
