ResumoChemical constituents obtained from ethanol extract of Auxemma glazioviana, a very common tree of Ceará State-Brazil, were analyzed and quantified by reverse-phase HPLC.To evaluate the quinone content of the extract, a simple, rapid and accurate high-performance liquid chromatography (HPLC) method was developed for the assessment of three bioactive quinones: glaziovianol 1, oncocalyxone A 2 and oncocalyxone C 3. The HPLC system used a Shimadzu octadecylsilyl silica (ODS) column with acetonitrile and water (1:1, v/v), as the mobile phase and detection at 280 nm.Quantitative analysis showed that 2 is the most abundant compound in both extracts EtOAc and CHCl 3 , with 35.9 and 39.9%, followed by 1 with 22.8 and 26.2%, respectively.
