Abstract:
Objective: To establish a new method and limit of detection for Flavonoids content in Fructus Crataegi. Methods: Flavonoids in Fructus Crataegi in 10 regions was determined by colorimetry. Results: Content of Flavonoids in samples selected from 10 regions ranged 0.84%～3.62%. Content of hyperoside by colorimetry is correlative to that by HPLC. Conclusion: The method is simple, quick and reproducible. Flavonoid content in Fructus Crataegi was designed no less than 1.0%, extraction must be performed under 60?C and dried to constant weight for 6 hours.
