目的:建立顶空气相色谱法测定小儿复方麻黄碱桔梗糖浆中薄荷脑的含量。方法:采用Agilent DB-WAX毛细管柱(30 m ×0.53 mm,1.0μm),FID检测器;进样口温度为:200℃,柱温:150℃,检测器温度:250℃;载气(氮气)流量:2.0 ml· min-1;分流比:1∶1;顶空平衡温度:80℃,平衡时间:30 min,进样体积:1 ml。结果:在该色谱条件下,薄荷脑在2.09~20.92μg ·ml-1的浓度范围内与峰面积呈良好的线性关系(r=0.9991);平均加样回收率为98.0%,RSD为1.8%(n=6)。结论:该方法简便、准确,重复性好,可用于测定小儿复方麻黄碱桔梗糖浆中薄荷脑的含量测定。
目的:建立頂空氣相色譜法測定小兒複方痳黃堿桔梗糖漿中薄荷腦的含量。方法:採用Agilent DB-WAX毛細管柱(30 m ×0.53 mm,1.0μm),FID檢測器;進樣口溫度為:200℃,柱溫:150℃,檢測器溫度:250℃;載氣(氮氣)流量:2.0 ml· min-1;分流比:1∶1;頂空平衡溫度:80℃,平衡時間:30 min,進樣體積:1 ml。結果:在該色譜條件下,薄荷腦在2.09~20.92μg ·ml-1的濃度範圍內與峰麵積呈良好的線性關繫(r=0.9991);平均加樣迴收率為98.0%,RSD為1.8%(n=6)。結論:該方法簡便、準確,重複性好,可用于測定小兒複方痳黃堿桔梗糖漿中薄荷腦的含量測定。

Objective:To establish an HS-GC method for the determination of menthol in Xiao ’ er Fufang Mahuangjian Jiegeng syrups. Methods:An Agilent DB-WAX column(30 m × 0. 53 mm,1. 0 μm)with an FID detector was used;the inlet temperature was 150℃, the detector temperature was 250℃;the flow rate of the carrier gas ( N2 ) was 2. 0 ml·min-1 , the split ratio was 1∶1; the headspace equilibrium temperature was 80℃, the balance time was 30 min, and the sample volume was 1ml. Results:The calibration curve of menthol was within the range of 2. 09-20. 92 μg·ml-1, which showed a good linear relationship (r=0. 999 1). The average recovery of menthol was 98. 0%(RSD=1. 8%, n=6). Conclusion: The method is simple, accurate and reproducible, and can be used for the determination of menthol in Xiao’ er Fufang Mahuangjian Jiegeng syrups.
