UV fingerprint identification of Isatis-Root Granules / 中成药

ABSTRACT

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.
