NUTRITIVE VALUE OF RHIZOME OF THE CANNA INDICA LINN. AND CHARACTERISTICS OF VARIOUS EXTRACTED MATERIALS FROM THE RHIZOME

Abstract

Rhizomes of Canna indica Linn. has its own great important medicinal value, so thenutritive value of the rhizome is determined. Rhizome of Canna indicais found rich in carbohydrate and have enough crude fiber (67.99 and 12.50% respectively) ; nutritive value being 319.15 Cal /100 g.Rhizome is rich in Potassium (24405 ppm) and sufficient in sodium, calcium and magnesium (7500, 1345 and 1610 ppmrespectively). Other biologically important metals Cu, Ni , Mn, Fe, and Zn are also in suitableamounts. The useful materials from therhizomes of Canna indica were extracted by using solvents of decreasing polarities, viz. Water, Ethanol, Diethyl ether and Petroleumether. The water extract has maximum yield. All of the solvent extracted materials are dextrorotatory.
