FTIR Spectroscopic analysis of Siddha herbo-mineral drug Kaaravediyuppu parpam

Abstract

In Siddha medicine the use of metals and minerals are more predominant in comparison to other Indian traditional medicine systems. Kaaravediyuppu parpam(KVP)is a herbo mineral drug in the literature of Kannusamy Paramparai Vaiththiyam, for Neerkattu. Aim is to characterize the KVPby the Fourier Transform Infrared Spectrophotometer (FTIR) spectroscopic method.Drug authentication was done inPGD of Gunapadam and Medicinal Botany Department, Govt. Siddha Medical College, Palayamkottai. FTIR Spectra were recorded at Kalasalingam Academy of Research and Education, International research center, Srivelliputhur. FTIR is perhaps the most powerful tool for identifying the types of chemical bonds (functional groups) present in compounds. The wavelength of light absorbed is characteristic of the chemical bond as can be seen in the annotated spectrum. In FTIR spectra analysis, this sample (KVP)exhibits the Peak value at 3360.00, 3062.96, 2798.71,2613.55, 2432.24, 2214.28, 2065.76, 1766.80, 1481.33, 1427.32, 1382.96, 1346.31, 1257.59, 1134.14, 1080.14 ,999.13 ,943.19 ,879.54, 827.46, 707.88, 603.72. This indicates the presence of organic functional groups such as Aliphatic primary amine, Alcohol, Aldehyde, Thiol, Nitrile, Carbodiimide, Acid Halide, Carboxylic acid, Sulfate, Sulfonyl chloride, Fluoro compound, Aliphatic ether, Primary alcohol, Alkene, 1,4-disubstituted, Benzene Derivative and Halo compound. Present work can be considered as the first step towards the identification of heavy metals and functional groups in KVP.
