板蓝根颗粒UV指纹图谱的识别

UV fingerprint identification of Isatis-Root Granules

目的:找到快速、简便识别板蓝根颗粒中是否含有板蓝根的UV指纹图谱,以及含有板蓝根该部分成分群量的多 少。方法:用Excel中的Correl函数计算板蓝根药材与板蓝根颗粒UV指纹图谱之间的相关系数。并对三家不同药厂生 产的板蓝根颗粒含UV图谱中板蓝根成分群的量进行了比较。结果:板蓝根药材与板蓝根颗粒UV指纹图谱之间有很好 的相关性。结论:板蓝根的UV指纹图谱可以识别板蓝根颗粒是否含有板蓝根以及含量的多少。

AIM: To find out characteristic UV spectum of Isatis Root Granules for identification. METHODS:Spectral correlation coefficient was calculated and compared between Isatis Root Granules and Radix Isatidis. Correl function from the Ms-Excel were applied for spectral calculation of three commodities. RESULTS: Spectral correlation coefficient was good between Isatis Root Ganules and Radix Isatidis. CONCLUSION: Fingerprint of Isatis Root can identificate whether granules contained isatis or not and its content.
