Abstract
The sourcing of novel bioactive compounds from bioresources has become a sustainability priority for several industrial sectors. Reliable methods are hence needed for the screening and identification of desired molecules in complex extracts. As such, phenolic compounds have attracted increasing interests due to their antioxidant potential.Here, a HPLC-UV based method was developed for the determination of phenolic compounds using a monolithic column. This allowed the separation of 23 phenolic compounds within 11 min. The method was ground proofed in terms of chromatographic parameters and applied to identify polyphenols in extracts of blueberries, basil and marine microalgae.The dominant polyphenols in blueberries and basil were chlorogenic acid (26.0 mg. kg -1) and kaempferol (61.4 mg. kg -1), respectively, while the microalgae used only contained trace amounts of polyphenols.This study demonstrates the value of our new HPLC method to rapidly screen extracts and identify polyphenols from biological matrices.
