中文摘要:目的 依据《德国药品法典》(Deutscher Arzneimittel-Codex,DAC)的相关规定,建立符合DAC要求的南五味子薄层色谱鉴别方法和含量测定方法,并比较DAC与《中华人民共和国药典》(以下简称《中国药典》)2020年版对以上2项内容规定的异同点。方法 采用硅胶GF254薄层色谱板,以乙酸-乙酸乙酯-甲苯(1∶18∶46)为展开剂,以五味子乙素和五味子醇乙为系统适应性测试(SST)指标,以五味子酯甲和五味子甲素为检测指标建立了南五味子的薄层色谱鉴别方法。以HALO Biphenyl色谱柱(250 mm×4.6 mm,5 μm)为固定相,乙腈-水为流动相进行梯度洗脱,检测波长为254 nm,流速为0.8 mL·min–1,柱温为35 ℃,以五味子酯甲和五味子酯乙的分离度为SST评价指标考察方法的可行性,建立了南五味子药材中五味子酯甲和五味子甲素的高效液相色谱法(HPLC)含量测定方法。结果 按照DAC相关要求进行了SST考察,结果显示,建立的薄层色谱鉴别方法具有良好的分离能力,可满足南五味子药材薄层色谱鉴别的要求;HPLC测定结果中五味子酯甲和五味子酯乙的分离度均大于3.5,符合SST要求,可用于南五味子含量测定;方法学考察结果均符合含量测定要求;31批五味子药材中五味子酯甲和五味子甲素的质量分数分别为0~0.761 1%和0.010 9%~0.790 9%,且2个成分含量呈正相关。结论 建立的南五味子薄层色谱鉴别方法和HPLC含量测定方法均符合DAC要求,且操作简便、结果准确、重复性好,可用于南五味子的质量控制;在药材的薄层色谱鉴别及含量测定方法方面,DAC与《中国药典》2020年版大致相同,但在SST方面存在差异,应加以重视。

Quality Control Methods of Schisandrae Sphenantherae Fructus Based on Requirements of Deutscher Arzneimittel-Codex
Abstract:Objective To establish the methods for identifying Schisandrae Sphenantherae Fructus based on thin-layer chromatography (TLC) and determining the content of indicator components according to the relevant requirements of Deutscher Arzneimittel-Codex (DAC), and compare the requirements on the identification and content determination between DAC and Chinese Pharmacopoeia (2020 edition).Methods The TLC-based identification method for Schisandrae Sphenantherae Fructus was established with silica gel GF254 thin-layer plate as the immobile phase, acetic acid-ethyl acetate-toluene (1:18:46) as the developing solvent, schizandrin B and gomisin A as indicators of system suitability test (SST), and schisantherin A and schizandrin A as detection indicators. The high performance liquid chromatography (HPLC)-based method for simultaneously determining the content of schisantherin A and schizandrin A was established with a HALO Biphenyl column (250 mm×4.6 mm, 5 μm) as the immobile phase and acetonitrile-water as the mobile phase for gradient elution at a flow rate of 0.8 mL·min–1 and a column temperature of 35 ℃. The resolution of schisantherins A and B was used as the indicator of SST to examine the feasibility of the established method.Results We conducted SST in accordance with the requirements in DAC. The SST results showed that the TLC-based method had good separation ability and met the identification requirements of Schisandrae Sphenantherae Fructus. The resolution of schisandrins A and B in the established HPLC-based method was above 3.5, indicating that the method met the requirements of DAC on SST and can be used for determining the content of indicator components in Schisandrae Sphenantherae Fructus. The results of methodological investigations demonstrated that the established HPLC-based method met the requirements for content determination. The content of schisantherin A and schizandrin A in 31 batches of Schisandrae Sphenantherae Fructus samples varied within the ranges of 0-0.761 1% and 0.010 9%-0.790 9%, respectively. Moreover, the content of the two components was positively correlated.Conclusion The established TLC-based method for identification and HPLC-based method for content determination both meet the requirements of DAC. The two methods are easy to operate and have accurate results and good repeatability, and they can thus be used for the quality control of Schisandrae Sphenantherae Fructus. DAC and Chinese Pharmacopoeia are similar in the identification of Schisandrae Sphenantherae Fructus based on TLC and content determination based on HPLC, except that there are differences in the SST, which deserves attention.
