Leírás

Általános leírás

(+)-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.

Alkalmazás

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-g- acrylic acid sodium salt (O-CMCs-g-AAS) copolymer deposited on magnetic graphene oxide (MGO), for sample pre-treatment and gas chromatography-mass spectrometry (GC-MS)
• 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
