The water distilled essential oils from leaves, stems and roots of Chrysanthemum parthenium (L.) Bernh. were analyzed by GC and GC/MS methods. The leaf oil was characterized by a high amount of camphor (56.4%), whereas in the stem oil, camphor (26.0%), trans-beta-ocimene (23.6%) and germacrene-d (15.0%) were the major constituents. The main components of the root oil were alpha-pinene (50.0%), trans-beta-farnesene (13.8%) and bicyclogermacrene (11.0%). Antibacterial activity of the leaf, stem and root oil were evaluated using the micro-dilution broth method. The oils showed inhibitory effects on Escherichia coli and Salmonella typhi, but were not active against Staphylococcus aureus.
采用气相色谱（GC）和气相色谱 - 质谱联用（GC/MS）方法分析了小白菊（Chrysanthemum parthenium (L.) Bernh.）叶、茎和根的水蒸气蒸馏精油。叶油的特征是含有大量樟脑（56.4%），而茎油中，樟脑（26.0%）、反式β - 罗勒烯（23.6%）和吉马烯 - d（15.0%）是主要成分。根油的主要成分是α - 蒎烯（50.0%）、反式β - 法呢烯（13.8%）和双环吉马烯（11.0%）。采用微量稀释肉汤法评估了叶、茎和根油的抗菌活性。这些精油对大肠杆菌和伤寒沙门氏菌有抑制作用，但对金黄色葡萄球菌无活性。
