    Abstract:ObjectiveStudy the variation of total flavones content in mulberry leaves from different growing seasons in order to use the leaves efficiently.MethodsUsing NaNO2-Al(NO3)3-NaOH spectrophotometry to determine the total flavones content in mulberry leaves from different growing seasons.ResultsThe variation of the total flavones content is remarkable.ConclusionThe total flavones content in mulberry leaves is low when the tree is in growing prophase and high in the period from the date of growth stopped to heavy frost.

    Key words:Mulberry leaves;Total flavones content; Growing season
