The roots of Angelica ursina MAXIM. (Umbelliferae) afforded seven known coumarins, glabra-lactone (1), osthol (2), xanthotoxin (4), bergapten (17), 7-methoxy-8-senecioylcoumarin (18), coumurrayin (19) and glabra-lactone hydrate (20) as well as a mixture of angelols (21). Further it became clear that 21 consisted of the group I-IV of angelols on the basis of 1H nuclear magnetic resonance spectral analysis and thin layer chromatography, though they are not yet investigated exactly. On the other hand the seeds of this plant afforded six known coumarins, imperatorin (3), umbelliprenin (8), heraclenin (22), heraclenol (23), tert-O-methylheraclenol (24) and 8-geranoxypsoralen (25).
