Natural coumarins. XII. Umbelliprenin, a constituent of ammi majus L. fruits.

The hitherto known free coumarins of Ammi majus L. fruits (xanthotoxin, imperatorin, bergapten, isopimpinellin, and isoimperatorin) are all psoralene derivatives. Umbelliprenin represents the first nonfuranoid coumarin to be found in this source, and its isolation is reported in this article.
