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]
