Abstract. Fourier transform infrared spectroscopy (FTIR) has been carried out to analyze the organic and inorganic constituent in human gallstones (n = 34) from Rajah Muthiah Medical College and Hospital. Statistical correlation between stone weight, age, stone type, no of pregnancy, food habit and chemical composition of gallstones were performed. The quantitative estimation was calculated for the particular peaks of bilirubinate salt (3421 cm–1), cholesterol (2932 cm–1), calcium palmitate (2849 cm–1) and calcium carbonate (1448 cm–1). The study reveals that mixed and brown type gallstones were predominant whereas black stones were less frequent in the selected region. Calcium carbonate is found all the stones, which is higher amount in mixed stones.
Key words: Gallstones, FTIR, quantitative analysis.
