    Abstract：ObjectiveTo observe the content dynamic variation of total flavonoids in Chrysanthemum morifolium Ramat.(CMR ) from different storage time and storage condition. MethodsUltrasonic method was used to extract total flavonoids in CMR of the different storage time, then the total flavonoids were determined. Results As the storage time and method differed ,the contents of total flavonoids showed marked variation. The content of total flavonoids of CMR also decreased with depositing time. ConclusionThe contents of total flavonoids were related to the storage time ......
