Chemical constituents from the roots of Angelica acutiloba and their chemotaxonomic significance

A chemical investigation of Angelica acutiloba isolated 26 compounds: 11 coumarins (1–11), 11 phthalides (12–22), one sterol (23), two polyacetylenes (24, 25) and one bisbenzopyran (26). Of these, several were isolated from some sources for the first time: compound 26 from the family Umbelliferae, compound 23 from the genus Angelica L. and ten compounds (1, 3, 5, 7, 9, 13, 17–19 and 22) from A. acutiloba. The chemotaxonomic significance of these constituents is also discussed.
