摘 要:目的建立气相色谱法测定复方九节茶乳膏中冰片的含量。方法以水杨酸甲酯为内标物,采用聚乙二醇(PEG)-20M毛细管柱,载气为N2,流速1.2 mL/min,进样口温度200℃,检测器温度220℃,程序升温,以内标法计算冰片含量。结果冰片在60.86~405.76μg/mL范围内线性良好,r=0.9998。平均加样回收率为100.62%,RSD为0.85%。结论该方法准确、灵敏,结果可靠,可用于复方九节茶乳膏的质量控制。Objective To establish a gas chromatography (GC) method for determination of synthet- ic borneol in compound Sarcandra Glabra ointment. Methods Methyl salicylate was used as internal standard substance. The gas chromatographic analysis was performed using PEG-20M capillary column, highly pure N2 was adopted as carrier gas at the flow rate of 1.2 mL·min-1, the inlet port temperature was 200℃ and the FID detector temperature was 220~C. The column temperature was raised by program and the content of synthetic borneol was calculated with internal standard method. Results The linear range of synthetic borneol was 60.86-405.76μg·mL-1(r=0.9998), the average recovery was 100.62% (RSD=0.85%). Conclusion The method is accurate, sensitive and reproducible, which can be used for the quality control of compound Sarcandra Glabra ointment.
