摘要
The volatile oils from \%Houttuynia cordata \%Thunb. were obtained with supercritical CO\-\{2\}, steam distillation and petroleum ether extraction and analyzed qualitatively and quantitatively by GC\|MS. The results showed that the chemical constituents of the volatile oils by three different methods are very different. The extraction rates of volatile oil by above\|mentioned three extraction methods are 1.764%, 0.040% and 0.082%, respectively. The volatile oil extracted by supercritical CO\-\{2\} extraction, which the content of houttuyninum reached 14.393%, is better than those with traditional methods.
