Abstract: The total flavanoids contents of Hotan walnut kernel septum membranes in the different extraction solvents by using spectrophotometric method with rutin as reference substance.Results showed that the total flavanoids content in alcohol by reflux extraction is the highest,6.430%.The total flavanoids content is 5.242% instead of alcohol with water.This method is simple and fast.It can be applied to the determination of the total flavanoids content in walnut kernel septum membranes.

Key words: walnut kernel septum membranes, total flavonoids, spectrometric method
