Abstract
Objective: To establish the methods of determination on the contents of total bile acid in Bile Arisaema by ultraviolet spectrophometry. Method: To add 50% sulfuric acid to the sample and react in water bath at 75 ℃. The contents of total bile acid were determined by ultraviolet spectrophometry on (377±2) nm
using chenodeoxycholic acid (CDCA) as the chemical reference substance. Result: The linear response range was 0.000 0~0.431 2 g ·L-1
r=0.999 1. The average recovery was 98.79%(n=5)
RSD 3.02%. Conclusion: The method was accurate
simple and reproducible which could be used for the determination of total bile acid in Bile Arisaema.
