ABSTRACT
OBJECTIVE:
To optimize extraction technology of flavonoids from Glechoma longituba by aqueous two-phase partitioning with ultrasonic extraction.METHODS:
The extraction technology of flavonoids from G.longituba were optimized by orthogonal experiment with ultrasonic extraction time,the volume fraction of propanol,the ratio of solid to solution,amount of(NH4)2SO4 as factors and with extraction rate of flavonoids from G.longituba as index.RESULTS:
The optimal conditions were as followsextracting for 30 min with ultrasonic wave,the volume fraction of propanol 50%,the ratio of solid to solution 130,and the amount of(NH4)2SO4 30%.CONCLUSION:
Established extraction technology which is characterized with simple operation and mild conditions shows great advantage.
