目的 　测定灯盏花素片的含量。 方法 　采用高效液相色谱法。色谱柱为 C1 8柱。 (10μm,4.6mm× 2 5 0 mm) ;流动相为甲醇 :水 (80∶ 2 0 ) ;流速 0 .9ml·min- 1 ,检测波长 3 3 5 nm;柱温 :室温。结果 　灯盏花素片在 2 0 μg～ 80 μg·ml- 1范围内 ,线性关系良好 ,平均回收率为 10 0 .2 % ,RSD为 1.5 3 %。 结论 　该法可用于灯盏花素片中灯盏花乙素的含量测定 Objective To determine the content of breviscapine tablets. Method using high performance liquid chromatography. The column is a C18 column. (10 μm, 4.6 mm × 250 mm); mobile phase: methanol: water (80: 20); flow rate: 0.19 ml·min - 1, detection wavelength: 3 3 5 nm; column temperature: room temperature. Results Breviscapine tablets had good linearity in the range of 20 μg～80 μg·ml-1. The average recovery was 10 0.2% and the RSD was 1.5 3%. Conclusion This method can be used for the determination of scutellarin in breviscapine tablets
