摘要
目的建立测定野鸦椿药材中鞣花的含量高效液相色谱法。方法色谱柱为WaterssymmetryC18柱(150mm×4.6mm,5μm),流动相为甲醇-0.1%磷酸3z(36:64),流速1mL/min,柱温为40℃,检测波长为254nm。结果鞣花酸进样量在0.129~2.06Ixg范围内与峰面积呈良好线性关系(r=0.9994),平均加样回收率为100.57%,RSD为2.43%(n=6)。结论该方法线性关系、精密度和准确度良好,专属性强,可作为野鸦椿药材中鞣花酸的质量控制方法。
Objective To establish a HPLC method for the determination of the ellagic acid content in Euscaphis Japonica(ThuMb. ). Methods 'File chromatographic separation was performed on the Waters symmetry C]s column (150 mm×4.6 mm, 5 μm) with methanol-0. 1% H3PO4 solution(36:64) as the mobile phase, the flow rate was 1 mL/min and the column temperature was 40 ℃. The detection wave length was 245 nm. Results The linearity of ellagic acid was in the range of 0. 129- 2.06 μg( r =0. 999 4), the average recovery rate was 100. 57%, RSD was 2.43% (n =6). Conclusion This method has good linearity, precision and accuracy strong speci- ficity. It can be used for the quality control method of ellagic acid in Euscaphis Japonica(ThuMb. ).
