RESULTS: Spots obtained from the test solutions had the same color in reference solution and medical material in the same location,and the blank solution had no interfernece.The linear range of albiflorin was from 0.53 μg to 1.06 μg(r=0.999 8),the average recovery was(100.3%.) The linear range of paeoniflorin was from 0.29 μg to 2.00 μg(r=0.999 9),the average recovery was(99.49%.) CONCLUSION: In TLC,the spots are very clear and specific to identify the herbal medicine in Guishao Soft Capsules.It is simple,quick,high precise and accurate for HPLC to control the quality of Guishao Soft Capsules.
