To determine tannins in Ershiwuweidatang Capsules (Flos Carthami, Fructus Chebulae, Fructus Terminaliae Billericae, Fructus Phyllanthi, etc.).Methods:
Tannins were determined by casein method.Results:
The contents of tannins in Ershiwuweidatang Capsules were 0.96%, 0.90%, and 0.85%, respectively. The gallic acid calibration curves were linear at the ranges of 0.8 ~4.0 ?g?mL -1 ( r = 0.999 ). The average recovery of tannic acid was 96.2% with RSD =1.4%( n =5).Conclusion:
The method was simple and reliable.
