摘要
目的:应用气相色谱法测定杜香萜烯中桧烯的含量.方法:以SE-30为固定液,涂布浓度为5%,柱温65℃,FID检测器,检测器温度200℃.结果:在该色谱条件下可分离并测定桧烯的含量,桧烯的线性范围为0.06～0.60mg·mL-1,r=0.9998(n=6).桧烯的平均回收率为100.3%,RSD=1.4%(n=5).结论:方法简便,结果准确,重现性好,可作为该制剂的质量控制指标.
AIM: To establish a gas chromatography method for the determination of sabinene in ledum terpenes from Ledum palustry L. METHODS: 5% SE 30 was adopted as the stationary phase, the temperature of column was set at 65 °C and FID detector with termperature at 200 °C . RESULTS: Sabinene in the preparation was gained satisfactory separation and assay under the chromatographic condition. The calibration curve of sabinene was good linear in the range of 0.06 0.60 mg·mL -1 . with the corelation coefficient r=0.9998(n=6) . The average recovery of sabinene was 100.3%, RSD=1.4%, (n=5) . CONCLUSION: The method is simple, highly repeatable and accurate, and it can be used to control the quality of the preparation.
