The chemical constituents of the essential oils hydrodistilled from rhizome parts of W.W. Sm. and Roxb, of family Zingiberaceae, growing in India, were analysed for the first time by GC-FID and GC-MS, respectively. A total of 30 and 29 components representing 99.62 and 96.74% of the total oil were identified in the essential oils of and , respectively. The major components of were bornyl acetate (31.32%), -pinene (14.49%), camphene (12.81%) and limonene (10.55%), whereas was dominated by -pinene (25.24%), -terpinene (24.62%), terpinen-4-ol (14.87%) and 1,8-cineole (7.51%). Essential oils were assessed for antioxidant potential using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging assay. oil exhibited stronger antioxidant potential as compared to oil and butylated hydroxytoluene (BHT). Thus, rhizome oil has the potential to be used as an alternative source of antioxidant.
首次分别采用气相色谱-氢火焰离子化检测器（GC-FID）和气相色谱-质谱联用仪（GC-MS）对生长于印度的姜科植物W.W. Sm.和Roxb.根茎部位水蒸馏所得挥发油的化学成分进行了分析。在W.W. Sm.和Roxb.的挥发油中，分别鉴定出了30种和29种成分，分别占总油含量的99.62%和96.74%。W.W. Sm.的主要成分是乙酸龙脑酯（31.32%）、α-蒎烯（14.49%）、莰烯（12.81%）和柠檬烯（10.55%），而Roxb.则以α-蒎烯（25.24%）、γ-松油烯（24.62%）、萜品-4-醇（14.87%）和1,8-桉叶素（7.51%）为主。采用2,2-二苯基-1-苦基肼（DPPH）和2'-联氮-双-（3-乙基苯并噻唑啉-6-磺酸）（ABTS）自由基清除试验对挥发油的抗氧化潜力进行了评估。与Roxb.挥发油和丁基羟基甲苯（BHT）相比，W.W. Sm.挥发油表现出更强的抗氧化潜力。因此，W.W. Sm.根茎挥发油有潜力作为抗氧化剂的替代来源。
