ABSTRACT: Zingiber rubens Roxb., and Zingiber zerumbet (L.) Smith were collected respectively from Nghe An, Province and Ha Tinh, Province,Vietnam. The root essential oils were obtained by water distillation and analyzed by Gas chromatography (GC) and Gas chromatography coupled with Mass spectrometry (GC-MS). The most abundant components of Z. rubens were (Z)-citral (30.1%), camphene (9.7%), β-phellandrene (7.5%) and 1,8-cineole (7.0%) and zingiberene (5.3%). The main oil constituents of Z. zerumbet were (Z)-citral (26.1%), camphene (16.3%), sabinene (14.6%), zingiberene (7.2%) and lavandulyl acetate (6.7%). This species has low zerumbone (1.2%) content.
