Abstract:
AIM: To establish the quality standards for Chinese extractum angelicae liquidum. METHODS: TLC was used to identify ferulic acid and ligustilide and HPLC to determine the content of ferulic acid and ligustil-ide. HPLC was performed on a Diamonsil ODS-C_(18) analytical column(250 mm×4.6 mm, 5 μm) with gradient elu-tion(0-15 min, 38%A; 15-20 min, 38%A-70%A; 20-40 min, 70%A; 40-45 min, 70%A-38%A) of methanol (A, containing 0.4% glacial acetic) and 0.4% glacial acetic acid(B) at the flow rate of 1.0 mL/min. The diode array detection wavelength was set at 323 nm and the column temperature was at 35℃. RESULTS: The linear range of ferulic acid and ligustilide were from 1.008 μg/mL to 10.08 μg/mL and 9.985 μg/mL to 99.85 μg/mL,the average recoveries of both were 98.11% and 101.61%, RSD were 1.58% and 1.32%. CONCLUSION: The method is rapid, simple and accurate with high reproducibility and can be used to control the quality of Chinese extractum angelicae liquidum.
