Geoffroea decorticans, commoly known as ?chañar? or ?chañarcillo? is a bush or tree widely spread in Argentina and used in popular medicine as emolient, balsamic, antitusive and expectorant. The aim of this paper is to analyze chañar bark, popularly used in decoctions and infusions for respiratory treatments.Samples were collected in San Francisco and Potrero de los Funes, of San Luis province. Pharmacognostic study revealed the presence of flavonoids and sterols through solvent extraction technique of increasing polarity. Screening was carried out by identification reactions thin layer cromatography of the infusions and decoctions (FA VI Ed.) The solvent mixture ethanol:water (40:60) proved to be the most efficient/effective to obtaind liquid extract. The electrophoretic analysis was applied to the separation and simultaneous determination of mayoritary compounds: oleanolic acid, stigmasterol and quercetine. The analysis time was less than 15 minutes. The use in folk medicine Geoffroea decorticans bark as expectorant and anti-inflammatory airways will be justified by the presence of these major components.
