Objective: To improve the quality standards for Arthritis Ointment. Methods: TLC was applied to identification of Angelica dahurica in qualitative identification. The camphor and borneol contents were determined by GC. Results: The TLC spots of A. dahurica were distinct and reproducible, and negative without interference. The linear ranges of camphor and borneol were 0.401 41-4.014 1 and 0.393 34-3.933 4 μg. The average contents of camphor and borneol were 6.038 0 and 5.353 9 mg/g. The average recoveries of camphor and borneol were 99.32% and 99.82%. Conclusion: The established quality standards are accurate, simple, and feasible, and could be used for quality control of Arthritis Ointment.
