Determination of chromones in Dysophylla stellata by HPLC: method development, validation and comparison of different extraction methods.
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.
