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.
