The monoterpenes 1,8-cineole, thymol, geraniol, menthol and camphor strongly inhibited the root growth of Zea mays L. seedlings. They induced an oxidative stress as measured by the production of malondialdehyde, conjugated dienes and peroxides. This oxidative stress depended on the length of the exposure and on the monoterpene applied. The total fatty acid content was measured and fatty acid composition was analyzed. Unsaturated fatty acids increased in the treated samples. The alcoholic and non-alcoholic monoterpenes appeared to have different modes of action.
单萜类化合物1,8 - 桉叶素、百里香酚、香叶醇、薄荷醇和樟脑强烈抑制玉米幼苗的根系生长。通过丙二醛、共轭二烯和过氧化物的生成量测定，它们诱导了氧化应激。这种氧化应激取决于暴露时间和所施用的单萜类化合物。测定了总脂肪酸含量并分析了脂肪酸组成。处理后的样品中不饱和脂肪酸增加。含醇和不含醇的单萜类化合物似乎具有不同的作用方式。
