BQC Total Flavonoid Assay Kit offers a rapid, simple, and reproducible method for quantifying the overall flavonoid content in a wide range of plant based samples.
Total flavonoid assay kit is based on the reaction between flavonoids and aluminium ion (Al+3), generating a yellow-coloured complex. The formation of the flavonoid-aluminium complex can be detected spectrophotometrically at 415 nm. Quercetin, a natural flavonoid, is used as a reference standard in this assay. The results are expressed as Quercetin Equivalents (QE).
