Gallic acid

An aromatic compound belonging to the phenols (polyphenols) within the tannins, which forms colourless needles or a crystalline, slightly brownish powder. It is a component of gallotannins, which, together with ellagtannins (see under tannins), are found in the fruits and leaves of blackberries, oak bark, gall apples, green tea, raspberries, currants and rose plants. The rose family also includes the grapevine (see also grapevine systematics). Gallotannins and ellagtannins break down into gallic acid and ellagic acid through acid hydrolysis. Gallic acid is used for the production of antioxidants in food, sunscreens and dyes.
