Quantitative analysis of some bile acids by differential scanning calorimetry combined with TLC

An analytical method useful for the quantitative determination of some bile acids is proposed. The analysis is carried out in two steps. The first is based on the thin layer chromatographic (TLC) separation of the bile acids on alumina plates. The second is based on the application of differential s...

Description
Summary:An analytical method useful for the quantitative determination of some bile acids is proposed. The analysis is carried out in two steps. The first is based on the thin layer chromatographic (TLC) separation of the bile acids on alumina plates. The second is based on the application of differential scanning calorimetry (DSC), which permits the characterization and determination of the amount of compound contained in each spot. The DSC signal is proportional to the amount of sample present in the spot layer, while the various peaks and peak temperatures are used to identify the separated compound.
