摘要
目的:建立大孔吸附树脂-HPLC-DAD法测定知黄汤中梓醇含量的方法。方法:色谱柱为shim-pack VP-ODS C18(250mm×4.6mm,5μm),流动相为乙腈-0.1%磷酸溶液(1∶99),检测波长210nm,流速1.0m L/min。结果:梓醇在0.88-8.8μg范围内线性关系良好(r=0.9996),平均回收率为99.01%,RSD=0.3%(n=6)。结论:该方法快速、简便、准确、可靠,可用于本品的质量控制。
Objective: To establish an macroporous resin and HPLC- DAD method of Determination capaltol in Zhi- huang decoction. Methods: The sample was separated on a Shimadzu VP- ODS( 250 mm × 4. 6mm,5 μm)with acetonitrile – 0. 1% Phosphoric acid( 1: 99). The detection wavelength was set at 210 nm. The flow rate was1. 0m L / min. Result: The calibration curve was linear over the range of 0. 88 - 8. 8μg( r = 0. 9996). The average recovery of the method was 99. 01%. The RSD of precision of the sample was 0. 3%( n = 6). Conclusion: The results showed that this method was rapid,simple,accurate and reliable,and it could be used for quality control of Zhi- huang decoction.
