Optimization of hydrodistillation extraction conditions of zerumbone from Zingiber zerumbet rhizome

The optimization of zerumbone extraction from Zingiber zerumbet was investigated using a hydrodistillation extraction method. 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 essent...
