摘要
目的建立柱前衍生化HPLC/UV法测定黄杨宁片中环维黄杨星D的含量。方法异氰酸苯酯为柱前衍生化试剂,流动相:甲醇-水(83∶17);ZORBAX SB-C18(250 mm×4.6 mm,3.5μm)柱分离;检测波长242 nm;流速:1 mL.min-1;柱温:30℃;进样量:10μL。结果环维黄杨星D在2~400μg.mL-1与峰面积呈良好线性关系,回归方程为:Y=2 616X+198.2(r=0.999 9);环维黄杨星D平均回收率为102.6%,RSD为0.4%(n=6);结论该法简单、准确度高、灵敏度好,为黄杨宁片质量控制提供了依据。
Objective To establish a pre-column derivatization of HPLC/UV method for the content determination of cyclovirobuxine D in Huangyangning tablets. Methods A pre-column derivation was developed by HPLC with phenylisocyanate. A ZORBAX SB-Cx8 column (250 min×4. 6 mm, 3. 5μm) was used and the mobile phase contained a mixture of methanol-water (83 : 17), with a flow rate at 1.0 mL ·min-1. The column temperature was 30℃. The UV detection wavelength was 242 nm. Results The calibration curve of cyclovirobuxine D was linear at 2~400μg·mL (r=0. 999 9). The average recovery was 102.6%, with RSD of 0. 4% (n=6). Conclusion The method is simple, accurate, sensitive and suitable for the quality control of Huangyangning tablets.
