The characteristic yellow matter, distributed throughout the plant, is especially concentrated in rhizomes. Curcuma longa is rich in carbohydrate; its protein value is not high while its mineral content is medium. Curcuma longa L. have been used traditionally as anti-inflammatory, anti-cancerous, choleratic, antimicrobial, antirheumatic, and antidiabetic (Govindarajan, 1980; Tonnessen, 1986; Velayudhan et. al, 1999; Kuttan et. al., 1985). It is also used as a source of coloring matter for foods, cosmetics and textiles. Turmeric is underground storage organ that is rich in secondary metabolites.
