title: Chemical composition of the essential oil of Zingiber zerumbet var. darcyi.
abstract: The chemical composition of essential oil obtained by hydrodistillation method from the rhizomes of Z. zerumbet var. darcyi was determined by GC and GC-MS. Thirty-three compounds, accounting for 93.6% of the oil were identified including twenty compounds in minor (0.1-0.6%) and eight in trace (<0.05%) amounts. The main compounds were zerumbone (69.9%) alpha-humulene (12.9%), humulene epoxide II (2.5%), caryophyllene oxide (1.1%) and camphene (1.9%). In this analysis, it has been found that the variety could be used as an additional new source of natural zerumbone besides Zingiber zerumbet. This is a first report on the analysis of Z. zerumbet var. darcyi oil.
