Abstract:
OBJECTIVE: To study the feasibility of quantitative analysis of multi-components by single-marker (QAMS) in determination of flavones in Shuanghuanglian preparations by comparing the results assayed by QAMS and external standard method (ESM). METHODS: The analysis was performed on a Xtimate™ C18 column (4.6 mm × 250 mm, 5 μm)with methanol and water containing 0.2% phosphoric acid as the mobile phase in gradient elution. The flow rate was set at 1.0 mL · min-1. The UV detector wavelength was 274 nm, and the column temperature was 30°C. RESULTS: Within the linear ranges, the analysis results showed no significant difference between QAMS and ESM. CONCLUSION: The QAMS method is credible and will be a new quality evaluation pattern for the determination of multiple flavones in Shuanghuanglian preparations.
