Revising Reverse-Phase Chromatographic Behavior for Efficient Differentiation of Both Positional and Geometrical Isomers of Dicaffeoylquinic Acids

<div>Comparisons of HPLC-PDA chromatogram profiles of nonirradiated (0 h) and UV irradiated (4 h) samples of (a) 3,5-diCQA analyzed on a Pinnacle C<sub>18</sub> column and (b) 4,5-diCQA analyzed on a Viva C<sub>18</sub> column, using aqueous methanol as the mobile phase composition.</div>
