The essential oils of the leaves, stems, rhizomes and roots of the medicinal plant Alpinia galanga from southern India were investigated by GC-FID, GC-MS and olfactometry. In all four samples, mono- and sesquiterpenes as well as (E)-methyl cinnamate could be identified. They are responsible for the characteristic odor as well as for the reported use in (folk) medicine and in food products of A. galanga. The essential oil of A. galanga leaves is rich in 1,8-cineole (28.3%), camphor (15.6%), beta-pinene (5.0%), (E)-methyl cinnamate (4.6%), bornyl acetate (4.3%) and guaiol (3.5%). The stem essential oil contains 1,8-cineole (31.1%), camphor (11.0%), (E)-methyl cinnamate (7.4%), guaiol (4.9%), bornyl acetate (3.6%), beta-pinene (3.3%) and alpha-terpineol (3.3%). 1,8-cineole (28.4%), alpha-fenchyl acetate (18.4%), camphor (7.7%), (E)-methyl cinnamate (4.2%) and guaiol (3.3%) are the main constituents of the rhizome essential oil. The root essential oil contains alpha-fenchyl acetate (40.9%), 1,8-cineole (9.4%), borneol (6.3%), bornyl acetate (5.4%) and elemol (3.1%). In addition, biological and aroma effects of the main and minor compounds of the four essential oils of Alpinia galanga are discussed in terms of their possible use in medicine, cosmetics and foods.
采用气相色谱 - 火焰离子化检测器（GC - FID）、气相色谱 - 质谱联用仪（GC - MS）和嗅觉测定法，对印度南部药用植物高良姜的叶、茎、根茎和根的精油进行了研究。在所有四个样品中，均鉴定出了单萜和倍半萜以及（E）-肉桂酸甲酯。它们赋予了高良姜特有的气味，也是其在（民间）医药和食品中应用的原因。高良姜叶的精油富含1,8 - 桉叶素（28.3%）、樟脑（15.6%）、β - 蒎烯（5.0%）、（E）-肉桂酸甲酯（4.6%）、乙酸龙脑酯（4.3%）和愈创木醇（3.5%）。茎精油含有1,8 - 桉叶素（31.1%）、樟脑（11.0%）、（E）-肉桂酸甲酯（7.4%）、愈创木醇（4.9%）、乙酸龙脑酯（3.6%）、β - 蒎烯（3.3%）和α - 松油醇（3.3%）。1,8 - 桉叶素（28.4%）、乙酸α - 小茴香酯（18.4%）、樟脑（7.7%）、（E）-肉桂酸甲酯（4.2%）和愈创木醇（3.3%）是根茎精油的主要成分。根精油含有乙酸α - 小茴香酯（40.9%）、1,8 - 桉叶素（9.4%）、冰片（6.3%）、乙酸龙脑酯（5.4%）和榄香醇（3.1%）。此外，还从高良姜四种精油的主要和次要成分在医药、化妆品和食品中的可能用途方面，讨论了它们的生物学和香气效应。
