Quantitative analysis of five phthalides, one polyacetylene, two unsaturated fatty acids and five furocoumarins in roots and leaves of Angelica acutiloba var. sugiyamae and wild Angelica plants collected in Hokkaido was studied. Phthalides and furocoumarins were contained in roots and leaves. Polyacetylene and unsaturated fatty acids were contained in roots, however in leaves, a small amount of these were identified. These plants were divided into each type by their chemical components. Phthalide contents were the highest in A. acutiloba var. sugiyamae and very low in A. acutiloba var. iwatensis. Chemical characteristics of furocoumarins were also different among them, oxypeucedanin and heraclenin which were not identified in A. acutiloba var. sugiyamae were confirmed in other plants. Ligustilide contents in the plants collected in Karikachi-toge whose external characteristics were similar to A. acutiloba var. sugiyamae were very low. Chemical characteristics also differed from cultivated A. acutiloba var. sugiyamae.
