In the present work, the response surface methodology (RSM) based on a central composite design (CCD) was used to determine the optimum condition for the extraction of essential oil and zerumbone content from Z. zerumbet rhizome.

From the experiment, the yield of Z. zerumbet essential oil was 4.10% slightly higher than the predicted value of the software (3.73%).
