补阳还五汤配方颗粒与传统汤剂的定性定量比较

Qualitative and Quantitative Comparison between Dispensing Granules and Decoction of Buyanghuanwutang

目的对补阳还五汤配方颗粒与传统汤剂进行定性定量比较。方法采用TLC进行定性比较,采用HPLC进行定量比较。结果TLC结果显示,配方颗粒与传统汤剂中化学成分的类型无明显差异,但传统汤剂的斑点更明显;建立了补阳还五汤中芍药苷的HPLC含量测定方法,并对精密度、重现性、稳定性和回收率等进行了考察;测定了配方颗粒与传统汤剂中芍药苷的含量,配方颗粒中芍药苷的含量约为传统汤剂中的1/6。结论两种剂型中化学成分的类型基本相同,但芍药苷的含量差异较大。

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. Conelusion The chemical constituents of the two preparations are similar, but the contents of paeoniflorin are different.
