WANG Gui-ling, GU Zheng-yi, MAO Yan, et al. Studies on Quality Standard of Tongzu Granules[J]. Chinese journal of experimental traditional medical formulae, 2013, 19(15): 89-91. DOI: 10.11653/syfj2013150089.
Objective: To establish the quality standards for Tongzu Granules. Method: The thin layer chromatography (TLC) was adopted for qualitative identification;aloin was detected by HPLC. Result: The identifying method of Aloe
Glycyrrhiza uralensis and Terminalia chebula were established. The determination method for the content of aloin was established. The calibration curve of aloin was liner in the range of 0.41-2.46 μg. The regression equation was Y=12 704X+48.84 (r=0.999 9). The average recovery was 96.39% and RSD was 0.76% (n=9). Conclusion: The method is simple
accurate and reproducible. It can be used for the quality control of Tongzu granules.
