ABSTRACT
Objective: To establish a method for the simultaneous content determination of 14 chemical components such as D- amygdalin, puerarin, hesperidin in Fenghan Ganmao Granules (FGG) by UHPLC-UV wavelength switching method, and chemometric analysis was used to analyze the quality differences. Methods: Separation was performed on an Agilent Poroshell 120 EC-C18 (150 mm × 2.1 mm, 2.7 μm) with a gradient elution of acetonitrile and 0.1% phosphoric acid. The content of 14 chemical components in 68 batches of samples from five manufacturers was determined by switching wavelength (210, 254, 310 nm). The radar chart, similarity evaluation, heat map and hierarchical clustering analysis, and principal component analysis (PCA) were used for data analysis. Results: The content of each component was as follows, D-amygdalin 0.063-3.885 mg/g, 3'-hydroxy puerarin 0.012-1.540 mg/g, puerarin 0.036-4.017 mg/g, 3'-methoxy puerarin 0.016-1.837 mg/g, puerarin-6″-O-xyloside 0.004-0.449 mg/g, mirificin 0.021-2.076 mg/g, daidzin 0.010-1.527 mg/g, prim-O-glucosylcimifugin 0.007-0.471 mg/g, 5-O-methylvisammioside 0.062-1.029 mg/g, hesperidin 0.210-8.453 mg/g, rosmarinic acid 0.001-0.237 mg/g, oxypeucedanin hydrate 0.007-0.204 mg/g, glycyrrhizic acid 0.056-1.311 mg/g, oxypeucedanin 0.002-0.042 mg/g, respectively. Chemometric analysis showed that there were some differences among the samples from different manufacturers, and the samples from the same manufacturer were more consistent. Conclusion: The method is simple, reproducible, and specific, which provides a reference method for the overall quality evaluation of FGG.
