(1) It was proved that catechin and epicatechin had a leading role during the final fermentation and storage of ciders in the process of non-enzymatic oxidation.

(2) Leucoanthocanin from grape seed extract ( catechin polymers ). A potent antioxidant that helps neutralise harmful free radicals.

(3) Content of catechin , epi- catechin and anthocyanins except condensated anthocyanins were decreased during aging phase, the new anthocyanins could be indentified after aging one year.

(4) A potent catechin, epigallocatechin gallate, or EGCG, is three to four times more abundant in green tea than black.

(5) Study on the specific adsorption of catechin gallates by cedar lignocellulose.

(6) The extrudate's total polyphenol content and total catechin content were independent of the die temperature.

(7) Relative to non-enzymatic oxidation, there was dimer of catechin, even trimer in its products[sentence dictionary], whose contents were more than in the condition of enzymatic oxidation.

(8) Then, catechin monomer was isolated and purified by HSCCC with the purity above 98 %.

(9) Wuxi Mingxin Bioengineering Co. LTD maim products cover green tea extract ( tea polyphenols, catechin ).

(10) In fruits with both astringent and bitter taste, the contents of chlorogenic acid, catechin, epicatechin, phloridzin, and procyanidins were the highest.

(11) Under the condition of enzymatic oxidation, it was studied by the experiment of oxidative polymerization of catechin, epicatechin, chlorogenic acid and caffeic acid in the cider model system.

(12) By using acetic ester as solvent, Tea Polyphenols and Catechin are separated from green tea.

(13) However, it was comparatively stable in the artificial simulation intestinal juice, and tea catechin wasn't affected by the saline material of pepsin, trypsin and buffer solution.

(14) DFR/LAR is very important enzymes in flavone biosynthesis pathway and have significant regulating function in catechin biosynthesis.
