摘要(Abstract):

目的 建立复方赤红颗粒中独活、川芎及芍药苷含量的测定方法。方法 分别取复方赤红颗粒、独活阴性样品及独活对照药材各1 g制备独活鉴别的供试品、阴性对照及对照药材溶液,分别取复方赤红颗粒(2 g)、川芎阴性样品(2 g)及川芎对照药材(0.1 g)制备川芎鉴别的供试品、阴性对照及对照药材溶液,采用薄层色谱法(TLC)对独活和川芎进行定性鉴别;取复方赤红颗粒(3 g)制备供试品溶液,采用高效液相色谱(HPLC)法测定芍药苷含量,进行线性关系、精密度、稳定性、重复性和加样回收率试验及上述3批样品的含量测定。结果 独活和川芎的薄层色谱中斑点清晰,阴性无干扰;芍药苷在5.22~167.04 mg/L范围内具有良好线性关系(r=0.999 0),精密度、稳定性及重复性试验的相对标准偏差(RSD)分别为1.14%、1.45%及1.39%;平均加样回收率为102.8%,RSD为1.36%;3批样品芍药苷平均含量分别为1.424 3 mg/g、1.409 1 mg/g及1.432 7 mg/g。结论 复方赤红颗粒的TLC方法专属性高,本研究建立的含量测定方法专属性强、分离度高及重复性好。
Objective To establish a method to determine the contents of heracleum, ligusticum wallichii, and paeoniflorin in compound Chihong granules. Methods One gram of compound Chihong granules, 1 g heracleum-negative sample, 1 g heracleum control medicinal materials were taken to prepare test substance, negative control and control medicinal material solutions for heracleum identification. Two gram of compound Chihong granules, 2 g Ligusticum wallichii-negative sample and 0.1 g ligusticum wallichii control medicinal materials were taken to prepare test substance, negative control and control medicinal material solutions for Ligusticum wallichii identification. Thin layer chromatography(TLC) was applied to qualitatively identify heracleum and Ligusticum wallichii. Three gram of compound Chihong granules were taken to prepare test sample solutions. High performance liquid chromatography(HPLC) was used to determine paeoniflorin content. Linear relationship, precision, stability, repeatability, and sample addition recovery tests were conducted. The contents of the three batches of samples mentioned above were determined. Results The spots in TLC of heracleum and Ligusticum wallichii were clear and negative without interference. Paeoniflorin had a good linear relationship within the range from 5.22 to 167.04 mg/L(r=0.999 0). Relative standard deviation(RSD)of precision, stability, and repeatability tests were 1.14%,1.45%, and 1.39%,respectively. Average sample addition recovery rate was 102.8%, and RSD was 1.36%. Average contents of paeoniflorin in three batches of samples were 1.424 3 mg/g, 1.409 1 mg/g and 1.432 7 mg/g, respectively. Conclusion TLC for compound Chihong granules has high specificity. Content determination established in this experiment has strong specificity, high resolution, and good repeatability.
