市售红参饮片质量分析

Quality Surveys of Ginseng Radix et Rhizoma Rubra Slices

目的： 调查市售红参饮片质量，制定红参饮片的质量标准。 方法： 收集不同地区市售红参饮片样品，采用性状观察，显微、薄层色谱定性鉴别，高效液相色谱进行含量测定。采用Lichrospher C18 （4.6 mm×150 mm，5 μm）色谱柱，乙腈-水进行梯度洗脱，检测波长203 nm，流速1 mL·min-1，柱温30 ℃。 结果： 市售红参饮片外观性状有差异，显微特征明显，薄层色谱在与人参对照药材、人参皂苷Rf、人参皂苷Rg1、人参皂苷Re及人参皂苷Rb1相应的位置上显相同颜色的斑点。13批样品中人参皂苷Rg1＋Re的含量范围为0.097 0%-0.301%，Rb1的含量范围为0.140%-0.310%。 结论： 不同地区市售红参饮片性状、显微特征及样品中3种成分的含量均具有显著的差异。

Objective： To survey the quality standards of Ginseng Radix et Rhizoma Rubra slices. Method： This experiment was carried out to observe the characters, identify the quality by microscopy and TLC, and make the content determination by HPLC for the Ginseng Radix et Rhizoma Rubra slices from different areas. The chromatographic column was Lichrospher C18（4.6 mm×150 mm, 5 μm） with gradient elution of acetonitrile and water. The detection wavelength was set at 203 nm;the flow rate was at 1.0 mL·min-1and the column temperature was set at 30 ℃ respectively. Result： The appearances of samples were different when micro-characteristic was obvious and TLC spots were clear on the corresponding position of ginseng control medicine, ginsenoside Rf, Rg1, Re and Rb1.Concentration range of Rg1＋Re was 0.097 0%-0.301% when concentration range of Rb1 was 0.140%-0.310% in thirteen batches of samples. Conclusion： The content of ginsenoside Rg1, Re and Rb1 was considerably different as well as the characters and micro-characteristics of slices.The study provides a reference for standards of Ginseng Radix et Rhizoma Rubra slices which need to be formulated.
