IDENTIFICATION OF CURCUMA LONGA RHIZOMES BY PHYSICOCHEMICAL AND TLC FINGERPRINT ANALYSISAbstract
Curcuma longa L. rhizomes are widely used by traditional medical practitioners for curing various diseases. The rhizomes of C. longa Linn. is commonly known as Haldi or Turmeric. Haldi is of particular importance to a human with the discovery that its rhizome powder, when added to various food preparations, preserves their freshness and imparts a characteristic flavor. The Indian system of medicine comprises of Ayurveda, Siddha, and Unani. In these systems, many medicines are made up of C. longa rhizomes. In Ayurveda, turmeric has been used internally as a stomachic, tonic, blood purifier and externally in the prevention and treatment of skin diseases. The World Health Organization (WHO) in 1999 had given a detailed protocol for quality control of single herbal drugs. We have developed a simple and rapid identification method for authentication of C. longa rhizome. Physicochemical parameters and TLC fingerprint analysis of C. longa rhizomes were also carried out. The study revealed different analytical parameters of the crude drug which will be useful in the identification of certain drug and control of adulterations.
