The word “Tannin” originally refers to the early use of oak and other barks in tanning animal hides into leather. Tannins (commonly referred as tannic acid) are water-soluble polyphenols commonly distributed in plants (The Editors of Encyclopedia Britannica 2016). The presence of tannins has been noted in both gymnosperms as well as angiosperms. The plant families that have been found to produce tannins are Actinidiaceae, Anacardiaceae, Aceraceae, Burseraceae, Bixaceae, Combretaceae, Dipterocarpaceae, Ericaceae, Grossulariaceae, and Myricaceae in case of dicots and Najadaceae and Typhaceae in case of monocots (Mole 1993). Additionally, tannins have been found to occur in numerous plant parts for instance: roots, barks, wood, fruits, and leaves. Apart from these they are also reported in galls resulting from the insect attacks. They can be present in any form ranging from a group of pale-yellow to light-brown amorphous powdery substances, flakes, or a spongy mass (The Editors of...
