目的:建立蒙药清血八味散中异土木香内酯和土木香内酯含量的方法。方法:采用高效液相色谱法,使用色谱柱为Diamonsil C18(250 mm×4.6 mm,5μm),流动相为乙腈-0.04%磷酸水溶液(60∶40),流速为1.0 mL·min-1,检测波长为194 nm,柱温为30℃。结果:异土木香内酯进样量在0.05~0.25μg、土木香内酯进样量在0.03~0.15μg范围内与峰面积具有良好的线性关系,平均回收率为异土木香内酯98.9%,RSD 1.65%;土木香内酯99%,RSD 0.62%。结论:该方法简便、快捷、准确、重复性好,可用于作为清血八味散中异土木香内酯和土木香内酯的含量测定。
Objective: To establish the method of Mongolian medicine Qingxue Bawei San in the content of helioxalin and geosmin. Methods: High performance liquid chromatography (HPLC) was used with Diamonsil C18 column (250 mm × 4.6 mm, 5 μm). The mobile phase consisted of acetonitrile-0.04% phosphoric acid solution 60:40 and the flow rate was 1.0 mL · min -1. The wavelength was 194 nm and the column temperature was 30 ℃. Results: The calibration curve was linear with the injection volume of isondumingol between 0.05-0.25μg and the range of 0.03-0.1μg, and the average recoveries were 98.9% , RSD 1.65%; Gerany lactone 99%, RSD 0.62%. Conclusion: The method is simple, rapid, accurate and reproducible. It can be used to determine the content of esovar and erigeron in Qingxue Bawei San.
