Extraction Optimization of Antibacterial Substances from Amomum tsao-ko

Abstract:

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.
