ABSTRACT: Turmeric Curcuma longa L. is a typical herbaceous plant belongs to Zingiberaceae family, is a major spice widely cultivated in tropical region of Asia. Turmeric is a rich source of curcuminoids, which is responsible for all the physiological properties. The content of curcuminoids may vary in plants grown in different agro-climatic zones. This study was undertaken to evaluate total curcuminoids content in the Ethylene dichloride (EDC) extract of C. longa rhizome collected from six different places of India. This study also focused to detect the percentage of three curcuminoids (Curcumin, Demethoxycurcumin and Bisdemethoxycurcumin) present by UV spectrophotometry and HPLC methods. These results provided a clear picture of the percentage of the isomers of Curcumin in various samples collected from different regions of India.
