Abstract
A colorimetric-equal value derivative spectrometry for the quantitative analysis of cholic acid in Niuhuang Jiedu Pian(tablet)containing 8 crude drugs is reported. The method is free from the interferuce of borneol rhubarb and other components without separation. The average recovery of cholic acid is 99.75 +/- 0.79% (X +/- CV).
