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]
This compound has an antioxidant activity leading to a cytoprotective effect.[11][13]
