The dynamic changes of secondary metabolites and tyrosinase activity of <i>Malus pumila</i> flowers were investigated during blooming for full use of <i>M. pumila</i> flowers. Phlorizin, astragalin and afzelin were selected as the indicators to determine the optimum extraction conditions of <i>M. pumila</i> flowers by HPLC analysis and three-factor and three-level orthogonal design experiments. When the smashing mesh number was 40 mesh, the ultrasonic time was 30 min, the solid-liquid ratio was ...[more]
