  • Some known coumarins, decursin, nodakenetin, umbelliferone, 7-demethylsuberosin, columbianetin, decursinol angelate and decursinol, showing significant cytotoxic activities against P388 cell lines,were isolated from the roots of Angelica gigas (Umbelliferae) . 7-Demethylsuberosin and columbianetinwere obtained from Angelica gigas for the first time. Chernotaxonornic difference about coumarins com-ponents between the roots of Angelica gigas and those of A. acutiloba is also discussed.

  • Thirteen compounds were isolated from the roots of Angelica genuflexa through repeated silica gel column chromatography. Nine coumarins, isoimperatorin (1), osthol (2), demethylsuberosin (3), oxypeucedanin (4), heraclenin (5), pabulenol (7), umbelliferone (8), oxypeucedanin hydrate (9) and marmesinin (11), and four chromones, hamaudol (6), cimifugin (10), sec-O-glucosylhamaudol (12) and prim-O-glucosylcimifugin (13), were identified by physicochemical and spectroscopic analysis. Among these, compounds 3, 5, 6, 8, 12, and 13 were isolated for the first time from the roots of Angelica genuflexa. These coumarins and chromones were examined for their anticomplement activity. Demethylsuberosin (3) showed a weak anticomplement activity with an $IC_{50}$ value of $390\;{\mu}M$.
