The essential oils from rhizomes of five Hedychium species, H. coronarium, H. neocarneum, H. flavescens, H. speciosum and H. stenopetalum (Zingiberaceae), were obtained by hydrodistillation and analyzed by capillary GC and GC/MS. Sixty components were identified and percentage oil yields from the fresh plants ranged from 0.06-0.17 % (v/w). All rhizome oils were rich in terpenes, especially monoterpenes (75.0-95.9 %). The most common compounds in the rhizome oils of Hedychium were beta-pinene, linalool and 1,8-cineole. The essential oils were tested against four bacterial strains. They showed moderate to weak activity against Gram-positive bacteria (inhibition zone 25-13 mm, MIC 0.3-8.3 mg/mL, MBC 0.6-8.3 mg/mL).
通过水蒸馏法从五种姜花属植物（姜科）的根茎中提取挥发油，这五种植物分别是：白姜花、新几内亚姜花、黄姜花、美丽姜花和窄瓣姜花，并采用毛细管气相色谱法和气相色谱 - 质谱联用法对其进行分析。共鉴定出60种成分，新鲜植物的出油率在0.06 - 0.17%（体积/重量）之间。所有根茎油都富含萜类化合物，尤其是单萜类化合物（75.0 - 95.9%）。姜花属根茎油中最常见的化合物是β-蒎烯、芳樟醇和1,8 - 桉叶素。对这几种挥发油针对四种细菌菌株进行了测试。它们对革兰氏阳性菌表现出中度至弱的活性（抑菌圈为25 - 13毫米，最低抑菌浓度为0.3 - 8.3毫克/毫升，最低杀菌浓度为0.6 - 8.3毫克/毫升）。
