[Study on UPLC fingerprint of Xiasangju Granules].
摘要
OBJECTIVE: To establish a UPLC fingerprint method of Xiasangju Granules. METHODS: UPLC analysis was performed on a Waters ACQUITY UPLC H-Class system and carried out at 30 °C on a Waters Column ACQUITY UPLC BEH C18 (2.1 mm x 50 mm, 1.7 μm). A binary gradient elution system was composed of acetonitrile (phase A)and 0.5% acetic acid solution (phase B). Detection was performed at the wavelength of 320 nm,the mobile flow rate was at 0.4 mL/min. A matrix including 16 variations (characteristic peaks area)and 12 samples was constructed for similarity evaluation, cluster analysis and principle component analysis. RESULTS: The results showed that the collected samples had a good similarity. A specificity fingerprint was produced and 16 characteristic peaks were designated. 12 samples were divided into 6 groups. CONCLUSION: It is a reliable, available and quick method for quality control of Xiasangju Granules.
