Methods The new method based on dispersive solid phase extraction coupled with high performance liquid chromatography (HPLC) was established. Using Alumia-N as adsorbent, the tra- ditional adsorbent activation, sample cleaning and target extraction were integrated as the “one-step” sample preparation process. Then the three antioxidants were a
