Baicalin was determined by HPLC. ResultsTLC spots developed were fairly clear, and the blank test showed no interference. Baicalin showed a good linear relationship in the concentration range of 0.116 8~0.584 0 μg,and the average recovery was up to 99.06%, RSD was 1.4%.ConclusionThe method is accurate, reproducible and simple. It can be used as the quality control of this preparation.
