Qualitative and Quantitative Comparison between Dispensing Granules and Decoction of Buyanghuanwutang

Objective To compare the chemical constituents between the dispensing granules and the decoction of Buyanghuanwutang. Methods TLC and HPLC methods were carried out for comparative analysis. Results TLC indicated the chemical constituents were similar between the dispensing granule and the decoction. The HPLC method was successfully established,and used for taking the contents of paeoniflorin in dispensing granule and the decoction of Buyanghuanwutang. The contents of paeoniflorin in dispensing granule were only one sixth of that in the decoction. Conclusion The chemical constituents of the two preparations are similar,but the contents of paeoniflorin are different.
