The essential oils from the leaves, flowers and roots of cultivated Alpinia speciosa K. Schum. were examined by capillary GC and GC-MS. Monoterpenoids composed 89.6% of the total identified constituents of the leaf oil, out of which 59.3% were oxygenated, represented mainly by terpinen-4-ol (28.4%) and 1,8-cineole (19.2%). The flower and leaf oils had a uniform qualitative, but different quantitative composition. However, the flowers oil was also dominated by oxygenated monoterpenoids (68.9%) viz., terpinen-4-ol (26.0%), 1,8-cineole (24.4%) and linalool (6.1%), along with the monoterpene hydrocarbon, sabinene (11.3%). On the contrary, the root oil had an entirely different composition and was characterized by endo-fenchyl acetate (40.1%), 1,8-cineole (11.8%), camphene (7.8%), bornyl acetate (6.9%) and borneol (5.8%). Moreover, endo-fenchyl acetate, exo-fenchyl acetate and endo-fenchol were characteristic of only the A. speciosa root oil.
采用毛细管气相色谱法（GC）和气相色谱 - 质谱联用法（GC-MS）对栽培的艳山姜（Alpinia speciosa K. Schum.）叶、花和根中的挥发油进行了检测。单萜类化合物占叶油总鉴定成分的89.6%，其中59.3%为氧化单萜类化合物，主要成分为萜品-4-醇（28.4%）和1,8-桉叶素（19.2%）。花油和叶油在定性上一致，但定量组成不同。然而，花油也以氧化单萜类化合物（68.9%）为主，即萜品-4-醇（26.0%）、1,8-桉叶素（24.4%）和芳樟醇（6.1%），以及单萜烃类化合物桧烯（11.3%）。相反，根油的组成完全不同，其特征成分是内-葑基乙酸酯（40.1%）、1,8-桉叶素（11.8%）、莰烯（7.8%）、乙酸龙脑酯（6.9%）和冰片（5.8%）。此外，内-葑基乙酸酯、外-葑基乙酸酯和内-葑醇仅为艳山姜根油所特有。
