摘    要:目的:建立高效液相(HPLC)测定鼻咽清毒颗粒中绿原酸的含量。方法:色谱柱为C18(5μm,250mm×4.6mm);流动相为甲醇-0.2%磷酸(用NaOH调节pH至2.8)(20:80);检测波长为323nm,柱温:25℃,流速:1.0mL·min^-4。结果:绿原酸进样量在0.02340-0.3744ug范围内与峰面积线性关系良好,r=0.9999,平均回收率为97.9%,RSD=0.60%(n=6)。结论:该方法简便,准确,重现性好。

关 键 词:高效液相色谱法  鼻咽清毒颗粒中  绿原酸

Abstract:Objective To establishes a HPLC method for chlorogenicacid of granuies Methods Uses RP-HPLC to dectect Volume was C18 ( 5μm, 250mm ×4.6mm) ,Mobilephase:methanol-0.2% phosphoric acid ( NaOH wasused to regulate pH 2.8) (20:80) ;Dectectwavelength is 323nm;The temperature of chromatopraph volume was 25℃,flow rate: 1.0ml/min. Results The ehlorogenicaci linear scope0.02340-0.3744μg (r=0.9999) ,The average recoveries were 97.98%,and the RSD was 0.60%; Conclusion The toothed was simple,accurate and reproductive.
Keywords:HPLC  biyanqingdu granuies  chlorogenicacid
