Study on Quality Standard Improvement for Buxue Yimu Granule / 中国药师

ABSTRACT

Objective:To improve the quality standard for Buxue Yimu granule. Methods: A TLC method was used to identify Angelica sinensis and Astragalus mongholicus. An HPLC method was used to determine the content of astragaloside in Astragalus mong-holicus on an Agilent Zorbax SB-C18column(250 mm×4.6 mm,5 μm),and the mobile phase was acetonitrile-water(32 68) at the column temperature of 35℃. The flow rate was 1.0 ml·min-1and the detector was ELSD. Results: The TLC spots were clear and showed a good separation. The linear range of astragaloside was 1.577-13.140 μg(r=0.999 2),the average recovery was 96.88%, and the RSD was 3.01%(n=6). Conclusion: The method is simple and accurate with good reproducibility, which can be used for the quality control of the preparation.
