Samples of marketed Lauha bhasma from different manufactures were evaluated chemically. Apart from the 81 -85% iron content, the 15-19% other constituents were determined therein. Ferrous ferric and total iron in a single aliquot were determined spectrophotometrically, Qualitative and chromatographic analysis indicate the presence of sodium, potassium, calcium copper and cobalt in the samples, silicious matter and traces of ascorbic acid were present while tannin was absent in Lauha bhasma . Quantitatively sodium and potassium were determined by flame spectrometry. Upon fractionation, water soluble and acid soluble contents were determined. |
