Optimization of extraction methods for determination of phosphodiesterase-5 (PDE5) inhibitors in premix coffee

An efficient analytical technique capable of analyzing three most common phosphodiesterase-5 (PDE5) inhibitors (vardenafil, sildenafil and tadalafil) simultaneously in premix coffee was developed. Sample extractions using either acetonitrile or methanol with two different extraction techniques (with...
