采用水蒸气蒸馏法从高良姜（Alpinia officinarum Hance）的新鲜根茎和干燥根茎中提取挥发油，并通过硅胶柱色谱法将其分离为烃类和含氧化合物组分。通过气相色谱（Kovat指数）和质谱数据确定了28种烃和29种含氧化合物。在新鲜根茎中，含量在1.0%以上的是1，8-桉叶素（50.0%），外-2-羟基-1，8-桉叶素乙酸酯（11.2%），β-卡隆烯（6.4%），α-和β-蒎烯（1.7和2.6%）、β-红没药烯（2.6%）、胡椒酚（2.0%）、柠檬烯（2.0%）、4-萜品醇（1.6%）、胡椒酚乙酸酯（1.2%）和甲基丁香酚（1.0%）。干燥后，根茎中的单萜类化合物（包括烃类和含氧化合物）含量减少，而倍半萜类和芳香族化合物含量增加。干根茎油的主要成分（含量大于2.0%）为β-红没药烯（9.6%），1，8-桉叶素（8.2%），醋酸胡椒酚（5.9%），查维考（5.3%），乙酸丁香油酯（3.7%），α-法尼烯（3.3%）、甲基丁香酚（3.3%）、β-香紫苏烯（2.9%）、α-红没药醇（2.6%）、匙叶烯醇（2.5%）、乙酸法呢酯（2.4%）、乙酸4-羟基肉桂酯（2.3%）。
The essential oils from fresh and dried rhizomes of galanga (Alpinia officinarum Hance) were obtained by hydro-distillation, and fractionated to the hydrocarbon and oxygenated compound fractions by silica gel column chromatography. Twenty-eight hydrocarbons and 29 oxygenated compounds were identified by gas chromatographic (Kovat’s index) and mass spectrometric data. In the fresh rhizome, the main components (over 1.0% in content) were 1,8-cineole (50.0%), exo-2-hydroxy-1,8-cineole acetate (11.2%), β-caryophyllene (6.4%), α- and β-pinenes (1.7 and 2.6 %), β-bisabolene (2.6%), chavicol (2.0%), limonene (2.0%), 4-terpineol (1.6%), chavicol acetate (1.2%), and methyl eugenol (1.0%). On drying the rhizome, the monoterpene fraction (including hydrocarbon and oxygenated compounds) de-creased in content, and the sesquiterpene and aromatic compound fractions increased. Major components of the oil from dried rhizome (over 2.0% in content) were β-bisabolene (9.6%), 1,8-cineole (8.2%), chavicol acetate (5.9%), chavicol (5.3%), eugenyl acetate (3.7%), α-farnesene (3.3%), methyl eugenol (3.3%), β-caryophyllene (2.9%), α-bisabolol (2.6%), spathulenol (2.5%), farnesyl acetate (2.4%), 4-hydroxycinnamyl acetate (2.3%).
