Abstract:
Objective: To establish quantitative analysis of multi-components with single marker (QAMS) for determination of 10 phloroglucinol contents in effective fraction of Dryopteris fragrans. Methods: The relative correction factors of nine phloroglucinol (aspidin PB, aspidin AB, flavaspidic acid BB, saroaspidin A, flavaspidic acid PB, disflavapidic acid PB, flavaspidic acid AB, compound VI, and aspidinol B) were determined by HPLC method with the aspidinn BB as the internal standard, which were to calculate the content of each. At the same time, external standard method (ESM) was used to determine the contents of 10 components in effective fraction, and the differences between the two methods were compared to verify the feasibility and accuracy of QAMS method. Results: The relative correction factor (RCF) was good. There was no significant difference between the quantitative results with the two methods in the 12 batches of 10 phloroglucinols. Conclusion: The established QAMS method can be used for quantitative analysis of D. fragrans with aspidinn BB as the internal standard in the absence of reference substances, and provided a reference for the multi-index quality evaluation in effective fraction of D. fragrans.
