Abstract:
AIM: To establish a fingerprint analytical method for ensuring the quality of Banlangen Granule (Isatis indigotica Fort). METHODS: According to pre column derivatization HPLC method, gradient elution with sodium acetate buffer (pH6.4) acetonitrile (95∶5) in a BDS C 18 column, was applied to detect amino acid at UV 360nm; and the coefficients of cosine of include angle and distance were employed to judge the quality similarity of the samples. RESULTS: The HPLC method is accurate and reproducible and makes almost all the peaks separated; and the two coefficients can show the similarity of each sample. CONCLUSION: The developed method is simple, accurate and operable and can efficiently control the quality of Banlangen Granule.
