Objective: To analyze western medicines added in Compound Arthritis Capsules by High performance liquid chromatography-diode array detector (HPLC-DAD). Method: To identify and determine of vitamin B1
piroxicam and prednisone acetate in compound arthritis capsules by HPLC-DAD. The HPLC conditions were as follows: column of Phenomenex luna ODS C18 (4.6 mm×250 mm
5 μm)
mobile phase consisted of acetonitrile-0.1% phosphoric acid solution (62 ∶38)
detection wavelength of 254 nm
flow rate of 1.0 mL ·min-1 and column temperature of 30 ℃. Result: Compound arthritis capsules contained vitamin B1
piroxicam and prednisone acetate and the contents were 22.6
13.8
7.12 mg ·g-1. Conclusion: The methods is simple
reliable and can used to analyze western medicines added in traditional Chinese medicines.
