Eight tocochromanols (α, β, γ, and δ homologues of tocopherol and tocotrienol) naturally occurring in foods were successfully separated within a 13‐min run in the RP‐HPLC mode. Analytes were separated on the Phenomenex Luna PFP column filled with the pentafluorophenyl stationary phase (3 µm, 150 mm ...
