摘要
目的建立丁蔻理中丸中丁香酚含量的高效液相色谱测定方法。方法样品采用Sep-PakC18小柱净化处理后用高效液相色谱法测定。色谱条件:KromasilC18色谱柱(200mm×4.6mm,5μm),甲醇-水(60∶40)为流动相,流速:1.0mL/min,检测波长:270nm。结果平均回收率为99.0%,RSD为1.8%(N=6)。结论本法简便、快速,测定结果准确可靠,可作为丁蔻理中丸的质量控制方法。
Objective: To establish a method for the determination of eugenol in Dikou Lizhong Wan. Methods: The sample was first purified on Sep-Pak C18 microcolumn. The chromatographic conditions were as follow: Kromasil C18 chromatographic column (200mm′4.6mm , i.d. 5mm), methanol-water mixed solution (60 ∶40) as mobile phase , the detection wavelength at 270 nm and the flow rate being 1.0 mL·min-1. Results: The average recovery of eugenol was 99.0 %and RSD= 1.8 %(N=6). Conclusion: This method was simple, convenient, rapid,accurate and reliable and it can be used to control the quality of Dikou Lizhong Wan.
