摘要
目的 建立脑塞通丸含量测定方法。方法 采用高效液相色谱法测定。色谱柱:SHIMADZU-GL Wonda Cract ODS-2,5μm,4.6mm×250mm,流动相:甲醇-水-磷酸(47∶53∶0.2),检测波长:280nm,柱温:30℃,流速:1.0ml·min-1。结果 黄芩苷的线性范围是0.200~1.000μg(r=0.9998),平均加样回收率是97.44%(RSD=1.57%)。结论 该方法操作简便易行,专属性强,准确可靠,可用于脑塞通丸的质量控制。
Objective To establish the method for the determination of baicalin in Naosaitong pills. Methods HPLC method was used. Column: SHIMADZU - GL Wonda Craet ODS - 2 5 μm ,4.6mm × 250mm, solution methanol - water - phosphoric acid(47 : 53: 0.2) , detection wavelength:280 nm, temperature:30℃ ,rate: 1.0mL · min-1 Results The linear ranges of baicalin were 0. 200 - 1. 000μg ( r = 0.9998 ). The average reeoverys were 97.44% ( RSD = 1.57% ). Conclusion The method is simple, spe- cific, accurate and reliable, can be used for the quality control of the Naosaitong pills.
