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.
