目的:建立合理快捷的乳香药材检验方法。方法:对乳香的不同炮制品建立薄层色谱鉴别方法,改进含量测定方法,采用溶剂直接提取药材中醋酸辛酯并利用GC法进行含量测定。结果:乳香薄层色谱分离良好,特征明显;醋酸辛酯在0.418~2.092μg之间线性关系良好(r=0.9999,n=6),平均加样回收率为94.6%,RSD为2.2%。结论:改进后的方法简便、准确,重现性好,可提高乳香药材检验检测的速度。
Objective: To establish a reasonable and quick method for testing medicinal materials of Frankincense. METHODS: TLC identification methods for different processed products of frankincense were established. The content determination method was improved. Octyl acetate was extracted directly from the herbs and the content was determined by GC method. RESULTS: The thin-layer chromatography of frankincense was well separated and its characteristics were obvious. The linear relationship between octyl acetate and 0.418~2.092 μg was good (r=0.9999, n=6). The average recovery was 94.6%, and the RSD was 2.2%. Conclusion: The improved method is simple, accurate and reproducible. It can increase the speed of inspection and detection of Frankincense.
