【摘要】 目的建立HPLC法测定参桂调经丸中丹皮酚的含量。方法采用AgilentHypersil-ODS-C18分析柱(250mm×4.0mm,5μm),以甲醇-水(70∶30)为流动相;检测波长为274nm,流速为1.0mL/min。结果线性范围为0.052～0.84μg(r=0.9999),平均回收率为99.94%(RSD=1.63%)。结论本法简便、灵敏、准确,可用于该制剂的质量控制。更多还原

【Abstract】 Objective To establish a method of HPLC for determining the Paeonol in Shengui Tiaojing Pill. Method Agilent Hypersil-ODS-C18 (250 mm×4.0 mm, 5 μm) was used, the mobile phase consisted of methanol-H2O (70∶30). The flow rate was 1.0 mL/min. The detecting wave length was at 274 nm. Results The method was linear at the range of 0.052～0.84 μg for Paeonol (r=0.999 9). The average recovery was 99.94%. Conclusion The method is simple, sensitive, accurate and can be applied to the quality control of Paeonol in Shengui Tiaojing Pill.更多还原
