D-catechin

Numerous studies were dedicated to the effects of flavonoids on microsomal and mitochondrial lipid peroxidation. Kaempferol, quercetin, 7,8-dihydroxyflavone and D-catechin inhibited lipid peroxidation of light mitochondrial fraction from the rat liver initiated by the xanthine oxidase system [126]. Catechin, rutin, and naringin inhibited microsomal lipid peroxidation, xanthine oxidase activity, and DNA cleavage [127]. Myricetin inhibited ferric nitrilotriacetate-induced DNA oxidation and lipid peroxidation in primary rat hepatocyte cultures and activated DNA repair process [128].

In Klein s Handbuch (loc. cit., p. 410), very few identifications of catechins are recorded. Apart from tea and cacao, recent work has shown them to be present in (1) apples (epzcatechin, commonly, catechin in some cider varieties (Bradfield, 1952, Williams, 1952)) (2) pears epi-catechin only in perry varieties in small amounts (Williams, 1952)) (3) peaches (d-catechin (Johnson et al., 1951)). 

There appear to be at least six catechin-like constituents, of which 2-epfcatechin is the principal one, with d-catechin, f-epfgallocatechin, and d-gallocatechin also present.
