[Determination of cholic acid in man-made bezoar by derivative spectrometry].
Cholic acid in man-made bezoar can be determined by the suggested first order derivative spectrometric method. The peak amplitude within 310-290 nm is independent of the other components and only varies linearly with cholic acid concentration. The method is simple and accurate with good reproducibility.
