复方生脉散的毛细管电泳指纹图谱研究

CE fingerprint of the compound Shengmai Powder

目的:利用毛细管电泳(CE)方法建立中药复方生脉散(红参、麦冬、五味子)的指纹图谱。方法:采用序贯式均匀设计的方法优化CE分离条件,确定生脉散指纹图谱的电泳条件为:以pH为9.5、44mmol/L硼砂、34mmol/LSDS为缓冲溶液体系,运行电压25kV,温度25℃,压力进样50mbar×100s,检测波长200nm。结果:11批生脉散CE指纹图谱中确认了20个主要的共有指纹峰,其中4个峰来自红参,6个峰来自麦冬,13个峰来自五味子,3个峰为红参和麦冬共有,1个峰为麦冬和五味子共有,另外1个为新成分。结论:该方法准确、可靠,可为生脉散的质量评价与控制提供科学依据。

AIM： To investigate the CE fingerprint of the compound Shengmai Powder（Radix et Rhizoma Ginseng rubra,Radix Ophiopogonis,Fructus Schisandrae chinensis）. METHODS： Sequential uniform design was used to optimize the separation conditions. A CE fingerprint for Shengmai Powder was established using buffer comprising 44 mmol/L borate and 34 mmol/L SDS at pH 9. 5,a running voltage of 25 kV,a capillary temperature of 25 °C and a wavelength of 200 nm. The sample was injected at a pressure of 50 mbar for 100 s. RESULTS： From the fingerprints of eleven batches of sample solutions,twenty main common peaks were determined. four peaks came from Radix et Rhizoma Ginseng,six peaks from Radix Ophiopogonis,thirteen peaks from Fructus Schisandrae chinensis,three peaks shared by Radix et Rhizoma Ginseng and Radix Ophiopogonis,one peak shared by Radix Ophiopogonis and Fructus Schisandrae chinensis and one new constituent. CONCLUSION： The developed method is accurate and reliable,and the fingerprint analysis can be used for the quality assessment and control of compound Shengmai Powder.
