The volatile constituents from the aerial parts of Houttuynia cordata(Yakmomil) originating in Korea(Ulleung-do) have been isolated by gas chromatography(GC) using two columns (OV-1 and PEG-20M) and identified by the comparison of their gas chromatograms or mass spectra with those of pure authentic compounds. The analysis shows that the volatile constituents of Houttuynia cordata of Korea are α-pinene, β-pinene, p-cymene, camphene, myrcene, limonene, linalool, geraniol, borneol, hornyl acetate, β-caryophyllene, humulene(α-caryophyllene), thymol, octanal, decanal, dodecanal, 2-undecanone, decanoic acid, dodecanoic acid, tetradecanoic acid and hexadecanoic acid.
