The essential oil obtained by steam distillation of dried aerial parts of Ambrosia trifida L. from Northeast China was analyzed by GC and GC-MS. The essential oil yield based on dried plant material was 0.12% and thirty-five compounds (corresponding to 86.7% of the total weight) were identified. The main components were: bornyl acetate (15.5%), borneol (8.5%), caryophyllene oxide (8.3%), alpha-pinene (8.0%), germacrene D (6.3%), beta-caryophyllene (4.6%), trans-carveol (2.9%), beta-myrcene (2.6%), camphor (2.4%) and limonene (3.2%). A. trifida essential oil demonstrated bactericidal and fungicidal activity against six bacterial strains and two fungal strains, using the agar diffusion method.
采用气相色谱（GC）和气相色谱-质谱联用（GC-MS）对从中国东北采集的干燥豚草地上部分经水蒸气蒸馏得到的精油进行了分析。基于干燥植物材料的精油得率为0.12%，共鉴定出35种化合物（占总重量的86.7%）。主要成分有：乙酸龙脑酯（15.5%）、冰片（8.5%）、氧化石竹烯（8.3%）、α-蒎烯（8.0%）、杜松烯D（6.3%）、β-石竹烯（4.6%）、反式香芹醇（2.9%）、β-月桂烯（2.6%）、樟脑（2.4%）和柠檬烯（3.2%）。采用琼脂扩散法，豚草精油对6种细菌菌株和2种真菌菌株表现出杀菌和抑菌活性。
