Abstract

Chemical analysis of turmeric (Curcuma longa L) cultivated in parts of the state of Maharashtra was carried out. Quantitative characterization of turmeric samples was carried out by determining moisture content, total ash, acid insoluble ash, starch, curcumin and lead and chromate levels in all the samples. The total ash levels were within limits of Agmark and indicated the purity of samples. About 51% level of starch in the samples indicate its commercial applicability also. The curcumin in samples varied from 3.34 to 9.45 g/100 g (dry basis). The UV-Vis method for curcumin was also validated by carrying out repeatability studies and determining the precision and accuracy in terms of LOD and LOQ measurements.
