(+)-Catechin is more bioavailable than (−)-catechin: Relevance to the bioavailability of catechin from cocoa

Free Radical Research, 2006
Catechin is a flavonoid present in fruits, wine and cocoa products. Most foods contain the (+)-enantiomer of catechin but chocolate mainly contains ( - )-catechin, in addition to its major flavanol, ( - )-epicatechin. Previous studies have shown poor bioavailability of catechin when consumed in chocolate.

Synergistic anti‐inflammatory effects of quercetin and catechin via inhibiting activation of TLR4–MyD88‐mediated NF‐κB and MAPK signaling pathways

Phytotherapy Research, 2019
The synergistic anti‐inflammatory effect of quercetin and catechin was investigated using lipopolysaccharide (LPS)‐stimulated macrophage RAW 264.7 cells. Results showed that the combined treatment of quercetin with catechin synergistically attenuated LPS‐

Improved oral bioavailability of the anticancer drug catechin using chitosomes: Design, in-vitro appraisal and in-vivo studies.

International journal of pharmaceutics, 2019
Catechin hydrate is a phytopharmaceutical with promising anticancer effects but poor bioavailability. This study aimed to elaborate catechin loaded chitosan-tethered liposomes (chitosomes) to enhance catechin oral bioavailability.

Stability and recovery of cyclodextrin encapsulated catechin in various food matrices.

Food Chemistry, 2019
Catechin is astringent in taste, sparingly soluble in water and sensitive to oxygen, light and pH. These properties restrict its application in food products.

The influence of processing conditions on catechin, caffeine and chlorophyll contents of green tea (Camelia sinensis) leaves and infusions

LWT, 2019
Green tea samples were produced from different roasting temperatures (200 and 300 °C) and drying temperature (80, 120 and 160 °C). Individual catechins, total catechins, caffeine, and chlorophylls content were all evaluated in dried green tea leaves and ...

A seco-catechin cyclization approach to 4→6-linked catechin dimers

Chem. Commun., 2014
A viable approach for the selective synthesis of the 4→6-linked catechin dimers is described. The regioselective union of an acyclic catechin precursor (seco-catechin) and an electrophilic catechin unit was achieved. Subsequent pyran cyclization constructed the requisite 4→6-linked dimeric structure.

Catechin solubilization by spontaneous hydrogen bonding with poly(ethylene glycol) for dry eye therapeutics.

Journal of Controlled Release, 2019
Catechin exhibits various pharmacological effects, yet its poor aqueous solubility limits its clinical use. Here, we investigate a facile catechin solubilization method via spontaneous hydrogen bonding between catechin and poly(ethylene glycol) (PEG ...

Gelatin films with nisin and catechin for minced pork preservation

Food Packaging and Shelf Life, 2018
The capacity of gelatin-based active films to extend the shelf-life of minced pork meat was investigated. In vitro antibacterial and antioxidant activity of films resulted from nisin and catechin incorporation, respectively.
