摘  要:目的:建立高效液相色谱法对清燥救肺汤中3个成分(苦杏仁苷、绿原酸、甘草酸)分析方法。方法:采用AgilentTC—C18(4.6mm×250mm,5μm)色谱柱,以乙腈(A)-0.1%磷酸水(B)为流动相,梯度洗脱,流速为1.0mL·min^-1,检测波长为207nm(0~50min,测定苦杏仁苷与绿原酸);237nm(50~80min,测定甘草酸铵)。结果:清燥救肺汤中3种成分分别为苦杏仁苷在0.2250—4.5000μg(r=0.9999),绿原酸在0.0705—1.4100μg(r=0.9997),甘草酸铵在0.1440~2.8800μg(r=0.9998)范围内线性关系良好;平均回收率分别为98.18%、97.94%和97.34%。结论:该方法准确可靠,重复性好,可用于清燥救肺汤质量控制。Objective : To establish an HPLC method for simultaneous determination of three constituents ( amygdalin, chlorogenic acid, glycyrrhizic acid) in Qingzaojiufei Decoction. Methods :The separation was performed on an Agilent TC - C18 (4.6 mm × 250 mm, 5 μm) column with the gradient elution of acetonitrile - water containing 0.1% phosphoric acid at the flow rate of 1.0 mL · min-1. The detection wavelength was 207 nm( determine amygdalin and chlorogenic) ; 237 nm(determine glycyrrhizic acid). Results:Amygdalin, chlorogenic acid and glycyrrhizic acid had a good linearity in the ranges of 0.2250 - 4. 5000 μg ( r = 0. 9999 ), 0. 0705 - 1. 4100μg ( r = 0. 9997 ), 0. 1440 - 2. 8800 μg ( r = 0. 9998), respectively. The average recoveries of three constituents were 98.18%, 97.94% and 97.34%. Conclusions: The developed method is rapid and accurate with high repeatability and stability, which is helpful to control the quality of Qingzaojiufei Decoction.
