Study on extraction of condensed tannins from Acacia mearnsii bark

DUAN Wen-gui,GENG Zhe,QIN Liu-mei(College of Chemistry and Chemical Engineering,Guangxi University,Nanning 530004,China)  
In this paper,microwave irradiation method,ultrasonic method and high pressure steaming method were applied to extract condensed tannins from Acacia mearnsii bark.The optimum extraction conditions were studied.The results showed that microwave method was the best method in the extraction of condensed tannins.The condensed tannins extracted by microwave irradiation method at the optimum conditions was characterized by IR,UV,TG-DTA and XRD methods.
