摘要
目的测定桂枝茯苓片中桂皮醛的含量。方法采用高效液相色谱(HPLC)法,色谱柱为Hypersil ODS C18(4.6×250mm,5μm),流动相为乙腈-0.1%磷酸溶液(38:62),,流速1.0mL/min,检测波长285 nm。结果桂皮醛在5.7696-57.696μg/mL呈现出良好的线性关系,相关系数为0.9999。加样回收率98.81%,RSD为1.73%。结论本方法快速简便,结果准确,可用于桂枝茯苓片的质量控制。
Objective To determine Cinnamaldehyde content in Guizhi Fulin Tablets.Methods HPLC method was used.The samples were separated on a Hypersil ODS Cl8 column with the mobile phase of acetonitrile-0.1% phosphoric acid（38∶62） and the detection wavelength was set at 285 nm.Results The calibration curve were linear in the range of 5.7696 ~57.696μg/ml（r=0.9999）.Its average recovery was 98.81%（relative standard derivative=1.73%）.Conclusion The method is quick,simple and accurate,and is practical to control the quality of Guizhi Fulin Tablets.
