摘 要:目的:建立了反相高效液相色谱法同时测定功劳去火片(功劳木,黄柏,黄芩等)中栀子苷、黄芩苷、盐酸小檗碱的含量。方法:采用KromasilC18色谱柱(250mm×4.6mm,5.0μm);流动相组成为A:乙腈,B:乙腈-0.5%三乙胺水溶液(磷酸调pH3.1)(10:90)梯度洗脱;流速1.0mlMmin,检测波长254nm。结果:栀子苷、黄芩苷和盐酸小檗碱的线性范围分别为:3.22~206μg/mL(r=0.9999),2.95~186μg/mL(r=0.9999)和1.64~104μg/mL(r=0.9999)。平均回收率均大于98.4%。结论:该方法专属性强,结果准确可靠,重现性好,可用于功劳去火片中栀子苷、黄芩苷和盐酸小檗碱的含量测定,以便更好地控制功劳去火片的质量。AIM: To establish a method of determining genpioside, baicalin and berberine in Gonglao Quhuo Tablets ( Caulis Mahoniae, Cortex Phellodendri Chinensis, Radix Scutellariae, etc). METHODS : The mobile phase composed of A acetonitrile ,B acetonitrile and 0.5% triethylamine ( Ph3.1 ) ( 10: 90). The flow rate was 1.0 mL/ min with the wavelength at 254 nm. RESULTS :The calibration curves were linear in the ranges of 3.22-206 mL( r = 0. 999 9) for genpioside, 2.95-186 μg/mL( r = 0. 999 9) for baicalin and 1.64-104μg/mL( r=0. 999 9 )for berberine hydrochloride, respectively. The average recoveries were not less than 98.4%. CONCLUSION : This HPLC method is convenient, rapid, accurate and could be used for quality control of production of Gonglao Quhuo Tablets.
