Development And Validation

An HPLC method with reflux as an efficient extraction method has been developed for quantification of chromones in Dysophylla stellata Benth. Separation was achieved on a C18 column with a mobile phase of 0.5% (v/v) acetic acid in water (A), and ACN (B) under gradient elution at 1 mL/min. Chromones (1 and 2) isolated from D. stellata were used as standards for method development and validation was achieved according to ICH guidelines. Extracts prepared by three different methods [reflux, ultrasonication and accelerated solvent extraction (ASE)] were used for analysis by the validated method. The proposed HPLC method is simple, accurate and selective for the separation and quantification of chromones in D. stellata.
