  • Description: <jats:title>ABSTRACT</jats:title><jats:p><jats:italic>Styrax camporum</jats:italic> Pohl, known in Brazil as ‘estoraque do campo’ or ‘cuia de brejo’, has been used in the treatment of gastrointestinal diseases. The therapeutic action of <jats:italic>S</jats:italic>. <jats:italic>camporum</jats:italic> has been attributed to the ethyl acetate fraction, although the chemical composition of this fraction has not yet been analyzed. In this study, a high‐performance liquid chromatography photodiode array detection (HPLC‐PAD) method for analysis of Brazilian <jats:italic>Styrax</jats:italic> species has been developed. The compounds egonol (1) and homoegonol (2) were found to be present in all the samples investigated by HPLC. These compounds were isolated by open column chromatography followed by preparative TLC, and were identified by <jats:sup>1</jats:sup>H NMR. Compounds 1 and 2 were thus proposed as phytochemical markers for <jats:italic>Styrax</jats:italic>, owing to their biological properties and presence in other <jats:italic>Styrax</jats:italic> species. The developed method has been validated and successfully applied for quantification of 1 and 2 in <jats:italic>S</jats:italic>. <jats:italic>camporum</jats:italic> dried leaves and crude ethanolic extracts from <jats:italic>S</jats:italic>. <jats:italic>ferrugineus</jats:italic> and <jats:italic>S</jats:italic>. <jats:italic>pohlii</jats:italic> aerial parts.
