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 ligustilide.HPLC was performed on a Diamonsil ODS-C_18 analytical column(250 mm?4.6 mm,5 ?m) with gradient elution(0-15 min,38%A;15-20 min,38%A70%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 ?g/mL to 10.08 ?g/mL and 9.985 ?g/mL to 99.85 ?g/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.
