| Application: | This analytical standard can also be used as follows:• Method development for the multi-determination of catechin and its diastereomers in the leaf extracts and infusions obtained from five Byrsonima species using high-performance liquid chromatography, combined with photodiode array (PAD) and circular dichroism (CD) detectors • Determination of catechin in commercial green and black tea samples using magnetic solid phase extraction (MSPE) based on a novel adsorbent— O-carboxymethyl-chitosan- • Multi-residue analysis of eight catechins and four theaflavins in three different commercial tea infusions (green, black, and oolong) by ultra high-performance liquid chromatography in combination with triple-quadrupole tandem mass spectrometry (UHPLC-MS-MS) • Simultaneous detection and quantification of four phenolic compounds— catechin, caffeic acid, rutin, and trans-cinnamic acid, using ultrasonic-assisted extraction and HPLC coupled with diode array detection from Physalis angulata L. plant material samples • Multi-residue determination of catechins, caffeine, and polyphenols, from 45 fresh Jukro tea leaf samples, collected at 40, 60, and 90-day intervals, by an HPLC-based method combined with PDA detection |
| General description: | (+)-Catechin is the enantiomer of the polyphenolic flavonoid, catechin. Known for its antioxidative nature, it is present in various herbs, vegetables, fruits, green teas, chocolates, and red wines. |
