摘要
目的 :建立测定双黄连口服液 (金银花 ,黄芩 ,连翘 ,等 )中连翘苷含量的方法。方法 :通过RP SPE法处理样品 ,再以RP HPLC作定量分析 ;色谱条件 :PRODIGYODS( 3) ( 15 0mm× 4 .6mm ,5 μm)C18柱为色谱柱 ,甲醇 水 冰醋酸 ( 4 0∶6 0∶1)为流动相 ,检测波长为 2 2 7nm。结果 :连翘苷色谱峰与其它色谱峰分离良好 ,进样量在 0 .1μg～ 2 .0 μg范围内 ,呈良好线性关系 (r =0 .9997) ,平均回收率为 10 2 .2 % ,RSD为 0 .6 1% (n =6 )。结论 :本法简便快捷 ,结果可靠 。
Objective: To establish a method for determination of forsythin in Shuanghuanglian Oral (Flos Lonicerae, Radix Scutellariae, Fructus Forsythiae, etc.) Methods: After processing by RP SPE (reverse phase solid phase extraction), the sample solution was measured by RP HPLC. The chromatographic conditions were: Prodigy ODS (3) (150×4.6mm,5μm) column as analytic column; MeOH H 2O HAc(40∶60∶1,V/V) as mobile phase; detection wavelength at 227nm; column temperature at 35°C ; flow rate at 1.0mL·min -1 . Results: The linear range of forsythin was 0.1～2.0μg, r =0.9997. The average recovery was 102.2%, RSD =0.61%( n =6). Conclusion: The method is simple, accurate, reproducible and can be used to enhance the quality control of this drug.
