DescriptionIsoquercitrin, also known as isotrifoliin or hirsutrin, belongs to the class of organic compounds known as flavonoid-3-o-glycosides. These are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C3-position. Thus, isoquercitrin is considered to be a flavonoid. Isoquercitrin is an odorless tasting compound. Isoquercitrin is found, on average, in the highest concentration within a few different foods, such as black chokeberries (Photinia melanocarpa), teas (Camellia sinensis), and green tea and in a lower concentration in lettuces (Lactuca sativa), redcurrants (Ribes rubrum), and black tea. Isoquercitrin has also been detected, but not quantified in, several different foods, such as sorghums (Sorghum bicolor), common wheats (Triticum aestivum), sweet bays (Laurus nobilis), bitter gourds (Momordica charantia), and bamboo shoots (Phyllostachys edulis). This could make isoquercitrin a potential biomarker for the consumption of these foods. Isoquercitrin is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. quercetin 3-glucoside. isoquercitrin is found in Abies nephrolepis, Acacia mangium ,
