Agasiache rugosa O.KUNTZE, collected in Kitami, Hokkaido, afforded 0.14% oil from the fresh herbs and 0.24-0.39% oil from the dry herbs, and the oil contained 83.5-92.2% of methyleugenol, 1.5-6.3% of methylchavicol, and 0.1-0.4% of safrole, together with small amonts of α-pinene, β-pinene, limonene, 3-octanone., p-cymene, 3-octanol, cis-β, γ-hexenol (?), 1-octen-3-ol, linalool, β-element, caryophyllene, humulene, δ-cadinene, and other unidentified compounds.
