摘　　要：目的:研究鱼腥草不同部位(器官)挥发油的化学成分。方法:采用水蒸气蒸馏法分别提取鱼腥草 W01—100叶、地上茎和地下茎的挥发油,并用 GC—MS 法对各化合物进行鉴定,峰面积归一法测定各成分含量。结果:从鱼腥草叶、地上茎和地下茎中共鉴定出化合物27种,其中共有化合物15种,分别占各器官挥发油总量的66.83%,94.55%,92.10%。叶中挥发油以癸醛、β-月桂烯、β-水芹烯为主;地上茎挥发油以甲基正壬酮、β-月桂烯、β-水芹烯为主;而地下茎挥发油则以甲基正壬酮、β-蒎烯、β-水芹烯为主。结论:鱼腥草不同器官挥发油化学成分组成基本一致,但各成分含量存在一定差异。Objective ：To study the chemical constituents of the essential oils from different parts （organs） of Houttuynia cordata Thunb. Method：Essential oils were obtained by steam distillation from the leaves, terrestrial stems and subterranean stems of H. cordata W01 - 100. The chemical constituents were separated and identified by GC - MS,and the relative content of each constituent was determined by area normalization. Results： Twenty - seven chemical constituents were identified,and 15 chemical constituents were the same in the leaves,terrestrial stems and subterranean stems,which took up 66. 83% ,94. 55% and 92. 10% of the essential oil of each organ, respectively. Decanal, β - myrcene and β-phellandrene were found to be the major constituents in the leaf essential oil,while 2 -tmdecanone, β- myrcene and β - phellandrene in the terrestrial stem essential oil and 2 - undecanone, β - pinene, β - phellandrene in the subterranean stem essential oil,respectively. Conclusion：The results show that different organs posses almost the same essential chemical constituents but the different relative contents.
