Natural Product Identification

Common Name

3,4',5,8-Tetrahydroxy-7-methoxyflavone

Description

Pollenitin belongs to the class of organic compounds known as flavonols. Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Thus, pollenitin is considered to be a flavonoid lipid molecule. Pollenitin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, Pollenitin has been detected, but not quantified in, tea. 3,4',5,8-Tetrahydroxy-7-methoxyflavone is found in Askidiosperma paniculatum, Atraphaxis pyrifolia, Camellia sinensis , Cheilanthes argentea, Ephedra aphylla, Notholaena standleyi, Notholaena sulphurea, Rhodiola crenulata and Rhodiola crenulata (HOOK.f.et Thoms.) H.OHBA. This could make pollenitin a potential biomarker for the consumption of these foods.
