Characterization of fruit products by capillary zone electrophoresis and liquid chromatography using the compositional profiles of polyphenols. Application to authentication of natural extracts

Capillary zone electrophoresis (CZE) and high performance liquid chromatography (HPLC) were applied to the authentication of fruit products based on the compositional profiles of polyphenols. Various sample treatments were used to maximize the overall recovery of polyphenols or specific fractions, s...
