Sequential injection analysis with chemiluminescence detection for rapid monitoring of commercial Calendula officinalis extractions

Abstract

SIA-CL was found to be a suitable method for pseudo real-time monitoring of plant extractions and determination of extraction endpoints with respect to antioxidant concentrations. The method was applied at-line in the manufacturing industry.

Ultra-high Performance Liquid Chromatography with Photodiode Array and Chemiluminescence Detection for the Determination of Polyphenolic Antioxidants in Erigeron acris L. Extracts

“…The relative heights of CL peaks of protocatechuic acid (peak 1), quercetin 3‐ O ‐glucoside (peak 6) and quercetin (peak 8) were considerably larger than their UV absorbance peaks at 290 nm. The difference in relative peak heights was also noticed by other researchers, for example Hughes et al () and Mnatsakanyan et al (). It can be explained by the fact that the CL responses (in contrast to UV responses) are dependent on the reactivity of the analyte towards the applied reagent.…”

“…In spectroscopic methods such as spectrophotometry, a faulty device design with the light stray as well as other factors may affect the spectra measurement accuracy and hence influence the range of linear detection (38). Recently, the chemiluminescence (CL) technique as a quantitative detection method gained much opportunity and attention, due to its high sensitivity merits, (wider linear range and low background signals) (39).…”
