Determination of quercetin in some natural products using reversed FIA-CL method

This paper reports a new and simple flow injection analysis with chemiluminescence (CL) system for determination of quercetin through the reverse flow injection technique. The method was based on the inhibition of the CL of H 2O 2-luminal-permanganate with quercetin. The reverse flow was used to avo...
