摘要 目的:建立高效液相色谱法同时测定不同产地车前子生品及盐炙品中车前素、毛蕊花糖苷和异毛蕊花糖苷3个主要活性成分的含量。方法:采用CAPCELL PAK C18MGⅡS5色谱柱(250 mm×4.6 mm,5μm),以甲醇(A)-水(B)为流动相,梯度洗脱(0~45 min,25%A→42%A),流速1.0 m L·min-1,检测波长210 nm,柱温30℃。结果:车前素、毛蕊花糖苷和异毛蕊花糖苷进样量分别在0.045~0.898μg(r=0.999 9)、0.212~4.234μg(r=0.999 9)和0.017~0.338μg(r=1.000 0)范围内与峰面积呈现良好的线性关系;平均回收率(n=6)分别为99.3%、100.0%和99.1%,RSD分别为0.52%、0.18%和1.9%。结论:该方法分离效率高,重复性好,经方法学验证,可用于车前子药材的质量控制。 Objective: To establish an HPLC method to simultaneously determine three main kinds of active con- stituents, namely, plantagoguanidinic acid, verbaseoside and isoverbascoside, before and after salt processing of Plan- taginis Semen from different habitats. Methods: The CAPCELL PAK C18 MG Ⅱ S5 column(250 mm ×4.6 mm,5 μLm) was used with the mobile phase of methonal ( A)-water ( B ) for gradient elution ( 0-45 min, 25 % A→42 % A ) at the flow rate of 1.0 mL · min-1. The detection wavelength was 210 rim, and the column temperature was at 30℃. Results: The linear ranges of plantagoguanidinie acid, verbascoside and isoverbaseoside were 0. 045-0. 898 μg (r =0. 999 9) ,0. 212-4. 234 μg(r =0. 999 9)and 0. 017-0. 338 μg(r = 1. 000 0) ,respectively. The average re- coveries( n = 6 )were 99.3% (RSD = 0.52% ), 100. 0% (RSD = 0. 18% )and 99. 1% (RSD = 1.9% ), respective- ly. Conclusion: Based on method validation, this method with high separation efficiency and good repeatability can be used for the quality control of Plantaginis Semen.
