HPLC法同时测定抗眩晕颗粒中盐酸川芎嗪和阿魏酸
摘要
目的:建立高效液相色谱法(HPLC)同时测定抗眩晕颗粒中盐酸川芎嗪和阿魏酸的含量。方法:色谱柱为AGTC18(4.6 mm×250 mm
Objective: To determine the contents of tetramethylpyrazine and ferulic acid in Kangxuanyun Granule.Method: C18 Column was used with methanol acetonitrile for chromatography-1% acetic acid glacial(1∶ 1∶5) at a flow rate of 0.8 mL.min-1.The detecting wavelength was set at 280 nm.Result: The content of ferulic acid and tetramethylpyrazine can be determined by HPLC.The linearity of tetramethylpyrazine was good in the range of 0.002 4 ~ 6.900 0 μg
r = 0.999 8;The linearity of ferulic acid was good in the range of 2.040 0 ~58.650 0 μg
r = 0.999 0.The average recovery of tetramethylpyrazine was 98.75%
RSD 1.12%
the average recovery of ferulic acid was 98.45%
RSD 0.63%.Conclusion: The method is simple reliable accurate and can be applied as the quantity control method of Kangxuanyun Granule.
