Английская Википедия:Catechin-7-O-glucoside
Catechin-7-O-glucoside is a flavan-3-ol glycoside formed from catechin.
Natural occurrences
Catechin-7-O-glucoside can be isolated from the hemolymph of the European pine sawfly (Neodiprion sertifer).[1] It also occurs in relatively large quantities in cowpea (Vigna unguiculata) as the dominant flavan-3-ol monomer, and actually accounts for up to 70% of cowpea proanthocyanidins (tannins).[2]
It can also be produced by biotransformation of (+)-catechin by cultured cells of Eucalyptus perriniana.[3]
Presence in natural traditional drugs
Catechin-7-O-glucoside can be found in paeoniae radix, the crude drug made from the roots of Chinese peony (Paeonia lactiflora),[4] in red knotweed (Bistorta macrophylla, also known as Polygonum macrophyllum),[5] in the stem barks of the Nepali hog plum (Choerospondias axillaris),[6] in the Korean plum yew (Cephalotaxus koreana)[7] and in Huanarpo Macho (Jatropha macrantha).[8] (−)-Catechin 7-O-β-D-glucopyranoside is found in the bark of Rhaphiolepis umbellata.[9]
Presence in food
It is found in buckwheat groats,[10] in the red bean (the seed of Vigna umbellata, formerly known as Phaseolus calcaratus),[11] in barley (Hordeum vulgare L.) and malt.[12] (−)-Catechin 7-O'-β-D-glucopyranoside is found in rhubarb.[9]
Health effects
This compound has an antioxidant activity leading to a cytoprotective effect.[11][13]
