High Performance Liquid Chromatographic Method for Rapid Determination of Thiamine and Riboflavin in Dairy Products
Abstract
A fast, simple and reliable high-performance liquid chromatographic method has been developed for the simultaneous analysis of thiamine and riboflavin. The chromatographic separation was performed on a mini C18 column (8.0 x 3.0 mm, length x I.D.) with isocratic elution using acetronitrile and 0.05 M acetate buffer (pH 7.0). Direct UV absorptions at wavelength of 232 and 266 nm were used for detection of thiamine and riboflavin, respectively. Both vitamins were separated in less than 8.0 min at flow rate of 0.10 ml/min. The linear calibration curves were obtained over the concentration range of 0.10 - 100 mg/L for thiamine and 0.25 - 100 mg/L for riboflavin with good correlation coefficients (r2 > 0.999). The precisions were measured in term of relative standard deviation (RSD) value. The RSDs of the method were in the range 0.34 – 1.90%. The percentage recoveries of both vitamins were obtained in the range of 81.83 - 102.70. The contents of both vitamins in milk samples were successfully determined by using the developed method. Compared with the conventional HPLC method, the proposed method has the advantage of being rapid, low cost and environmentally friendly.
