Extraction optimization of antibacterial substances from Amomum tsao-ko
The aim of this work was to optimize extraction procedure of antibacterial compounds from amomum tsao-ko and verify antibacterial ability of yields.Two methods were carried out and compared.One is ethanol reflux extraction,and the other is ultrasonic-assisted ethanol extraction which selected due to better antibacterial efficiency of the extract obtained.In order to improve extraction rate and antibacterial activity which both varied with ultrasonic-assisted extraction conditions,Box-Behnken design was employed.Studies showed that the optimum conditions for extraction antibacterial substances from amomum tsao-ko were determined to be:ethanol density 100%,soaking time 4h,extraction time 120min.
