Catechin-7-O-glucoside 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] 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).

[9] 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.

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