摘  要:目的:研究 HPLC 法同时测定六味络通胶囊中绿原酸、阿魏酸及甘草苷含量。方法:采用 Kromasil C_(18)柱(150 mm×4.6mm,5 μm)以乙腈(A)-2%醋酸水溶液(B)为流动相,梯度洗脱:0 min(6%A)→15 min(6%A)→18 min(12%A)→35 min(12%A)→40 min(50%A),二极管距阵检测,测定波长:绿原酸、阿魏酸用324 nm,甘草苷用276 nm。结果:绿原酸、阿魏酸、甘草苷分别在0.21~3.3μg、0.05~0.80μg、0.23~3.7μg范围内有良好的线性关系,r=0.9999。平均加样回收率(n=6)分别为98.6%,100.2%,98.3%。结论:操作简便,结果可靠,重复性好,可作为该产品质量控制的方法。Objective:To establish an HPLC method for the determination of chlorogenic acid, ferulic acid and liquiritin in Liuweiluotong capsules. Methods:A Kromasil C18column( 150 mm × 4. 6 mm,5 μm) was used. The mobile phase was acetonitrile (A) - 2 % acetic acid ( B ) with gradient elution [ 0 min ( 6 % A) →15 min ( 6 % A) →18 min ( 12% A)→35 min ( 12% A) →40 min ( 50% A) ]. Chlorogenic acid, ferulic acid and liquiritin were determined by dual wavelength, chlorogenic acid and ferulic acid used 324 nm, liquiritin used 276 nm. Results:The linear ranges of chlorogenic acid ,ferulic acid and liquiritin were 0. 21~3.3 μg,0. 05~0. 80 μg,0.23 ~ 3.7 μg respectively. The average recoveries of them were 98.6% , 100. 2% and 98.3% respectively. Conclusion :This method is convenient, rapid and accurate. It can be used for quality control in production of Liuweiluotong capsules.
