Turmeric (Curcuma longa) is a rhizomatous herbaceous plant belonging to the ginger family Zingiberaceae. The main components of tumeric are 1,7-bis-(4-hydroxy-3-methoxy-phenyl)-hepta-1,6-diene-3,5-dione (also known as curcumin),which can exist in keto and enol forms (tautomers), and its desmethoxy and bis-desmethoxy derivatives which are present in varying ratios.
