Catechin-7-O-glucoside is a flavan-3-ol glycoside formed from catechin.

Natural occurrences

Catechin-7-O-glucoside can be found in Bergenia ciliata[1] or can be isolated from the hemolymph of the European pine sawfly (Neodiprion sertifer).[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 roots of the Chinese peony (Paeonia lactiflora),[4] in the 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]

Presence in food

It is found in buckwheat groats,[9] in the red bean (the seed of Vigna umbellata, formerly known as Phaseolus calcaratus),[10] in barley (Hordeum vulgare L.) and malt.[11]

Health effects

This compound has an antioxidant activity leading to a cytoprotective effect.[10][12]
