Keyword:  藏药 牛尾蒿油滴丸 β-蒎烯 气相色谱法 质量控制;
Abstract: 目的:建立测定牛尾蒿油滴丸中β-蒎烯含量的方法。方法:气相色谱法,采用填充色谱柱(3m×3mm),固定相为8%二乙二醇丁二酸酯,汽化温度180℃,柱温120℃,载气(氮气)流速10mL·min~(-1)。结果:β-蒎烯的理论塔板数为2106,回归方程为 Y=2.705×10~5X-3.544×10~3(r=0.9999),线性范围为0.2163~3.460mg·mL~(-1),平均回收率±RSD 为99.16%±0.59%。结论:以该法测定主要有效成分β-蒎烯的含量,理论塔板数较高、分离度较好。该方法可用于牛尾蒿油滴丸的质量控制。
