Abstract

Objective To explore the effect of different extraction methods on the content of total flavones from propolis.Methods Using Rutin as standard material,a UV determination method was studied the content of total flavones extracted from propolis at 502nm.Results The linear regression equation of the UV determination method is A=0.01149C+0.00772.The precision(RSD%,n=6) is 0.02 and the recovery is 99.92%(n=4).Conclusion The ultrasonic extraction method is better than methanol Soxhlet extraction method.The ultrasonic extraction method was simple,effective and practical,and could be used to determine the content of total flavones from propolis when necessary.
