摘 要:目的建立高效液相色谱法(HPLC法)测定生化汤协定方代煎液中游离阿魏酸和总阿魏酸含量的方法。方法应用HPLC法测定游离阿魏酸和总阿魏酸的含量,以Diamonsil C18柱(4.6 mm×250mm,5μm)为色谱柱,甲醇-1%醋酸溶液(30∶70)为流动相,检测波长为321 nm。结果游离阿魏酸在进样量0.212~1.060μg范围内呈良好的线性关系,回归方程为Y=4.685 5×106X-2.109 0×104(r=0.999 9),游离阿魏酸平均加样回收率100.60%,相对标准偏差(RSD)=2.33%,总阿魏酸平均加样回收率99.43%,RSD=2.65%。结论本方法操作简单,方法可靠,结果准确,灵敏度高,重现性好。Objective To establish a method for determination of free and total ferulic acid in decoction of Shenghua prescription by high performance liquid chromatography( HPLC).Methods On Diamonsil C18( 4.6mm × 250 mm,5 μm); with methyl alcohol( containing 1 % acetic acid) = 30∶ 70 as mobile phase and UV determination at 321 nm.Results A good linearity was obtained over the range of 0.212 ~ 1.060 μg for free ferulic acid,regression equation was Y = 4.685 5 × 106X-2.109 0 × 104( r = 0.999 9).The average recoveries of free and total ferulic acid components were 100.60% with relative standard deviation( RSD) = 2.33% and 99.43% with RSD = 2.65%,respectively.Conclusion This method is simple,reliable,accuracy,with high sensitivity and better repeatability.
