UPLC Profiles of Phytochemical Antioxidants. A UPLC
method was successfully established for both the carotenoids and
the phenolics22 (Figures 2 and 3). These methods have shortened
the run time to 1/31/4 (15 min for carotenoids and 13
min for phenolics, respectively) of that of a conventional HPLC
method; however, the separation was comparable to that of the
latter methods.1
