Abstract: Essential and absolute oil was extracted from Houttuynia cordata Thunb with two dif-ferent ways of petroleum ether and steam distillation. 43 constituents were elucidated by qualita-tive and quantitative analyses of GC / MS. It is revealed that the content of houttuyninum in ab-solute oil is much higher than that in essential oil. The chemical constituens in both essential and absolute oil are similar except fatty acid esters.

摘要： 对黔产野生鱼腥草(Houttuynia cordata Thunb)采取水蒸汽蒸馏和石油醚萃取的两种方法提取精油和净油。用GC/MS进行定性、定量分析，鉴定了其中48种成分。比较两种提取方法的分析结果，发现净油中抗菌有效成分鱼腥草素(houttuyninum)的含量明显高于精油中的含量。除高沸点的脂肪酸酯外，两者其它化学成分无明显差异。
