Variation of amino acids in some biological and pharmaceutical sample ft-ir study

Abstract: Variation of amino acids between biological sample ( Rice powder, nelli powder an lemon powder) and pharmaceutical sample ( Vitamin A , Vitamin B12 and Vitamin C) has been studied using FTIR spectroscopy. Spectroscopic analyses of biological and pharmaceutical samples are discussed. It has been found that the variation in amino acids with the variation in biological and pharmaceutical samples are correlated and the present study confirms the total amino acid content is very much lower in biological samples compared to pharmaceutical sample. Also an attempt has been made to correlate the extinction co-efficient (K) values with the changes in amino acid and phenols of the biological and pharmaceutical sample. The result shows amino acid and phenol groups are more in pharmaceutical samples then biological sample.
