PHYTOCHEMICAL SCREENING AND ANTIOXIDANT ACTIVITY OF RHIZOME PART OF CURCUMA ZEDOARIA

Abstract

Curcuma zedoaria belongs to the family Zingiberaceae . The rhizome parts of Curcuma zedoar ia was dried, extracted with different solvent by soxhlet extraction meth od. Phytochemical studies of all the crude extracts showed the presence of terpeniods, alkaloids, saponins, flavanoids, glycosides & carbohydrates, phenolic, tannins and phytosterols etc., The phytochemical results confirm that all extracts contains more important chemical constituents for various biological activities. Antioxidant activity (DPPH) has been carried out for all the crude extracts of Curcuma zedoaria . From the results, it was found that the different crude extracts from the rhizome part of the plant material had shown potent antioxidant activity. The Maximum antioxidant activity was seen in Ethyl acetate, n - hexane and water extracts, whereas petroleum ether, chloroform and ethanolic extracts of the plant material had shown moderate antioxidant activity. The present paper deals with the phytochemcial screening and antioxidant activity for all crude extracts of the plant material.
