Abstract:
Objective: To develop a HPLC method for the content and uniformity of dosage units of dehydroandrographolide in Xiaoyanlidan Tablets. Methods: ODS column was used and methanol water (70∶30) was used as a mobile phase. The detection wavelength was set at 250nm. Results: The linear range was from 2.14 to 34.24?g/mL (r =0.9999). The average recovery was 99.91%, and the relative standard deviation was 1.78%. Conclusion: The method is convenient and accurate.
