Technical Abstract: The extractability of the phenolic compounds is influenced by their chemical structure, degree of polymerization, and interaction with other components in the matrix. This talk describes the influence of sample preparation parameters (extraction techniques, extraction solvents, temperature, pressure, particle size, number of extraction cycles, and solid-to-solvent ratio) in developing analytical methods for accurate estimation of bioactive phenolic compounds present in the foods using parsley flakes as a model substrate.
