Biosynthesis of furanocoumarins in parsnips

Phytochemistry, 1970
Abstract Labelling experiments have shown that umbelliferone, and to a lesser degree p -coumaric acid, are precursors of bergapten, imperatorin, isopimpinellin and xanthotoxin in Pastinaca sativa L. C-2 and C-5 of mevalonate, which has been proposed as a precursor of two furan ring carbons and of dimethylallyl substituents, were both incorporated ...

Separation and determination of coumarins including furanocoumarins using micellar electrokinetic capillary chromatography.

Talanta: The International Journal of Pure and Applied Analytical Chemistry, 2018
The conditions of micellar electrokinetic capillary chromatography for separation and simultaneous measurement of coumarins (coumarin, scoparone, isoscopoletin, esculin, esculetin, umbelliferone) including furanocoumarins (xanthotoxin, byakangelicin ...

Mass spectrometry of some furanocoumarins

Canadian Journal of Chemistry, 1979
The mass spectra of two isomeric methoxyfuranocoumarins have been investigated using electron-impact ionisation. Unambiguous distinction between the two isomers is possible through a combination of conventional mass spectra with collision-induced dissociations of the molecular ions and of selected fragment ions.

Collective Synthesis of Furanocoumarin Natural Products Through a Radical‐mediated Construction of Furanocoumarin Skeletons

Asian Journal of Organic Chemistry
AbstractFuranocoumarins are attractive targets in the synthetic organic and medicinal chemistry field because of their structural diversity and interesting biological properties. Herein, we describe the synthesis of furanocoumarin natural products from common furanocoumarin skeletons.

Biosynthesis of furanocoumarins in diseased celery

Phytochemistry, 1969
Abstract Celery infected with the pathogenic fungus Sclerotinia sclerotiorum incorporates cinnamic acid-114C, formate-14C, and methionine-14CH3 into xanthotoxin (8-methoxypsoralen), but not into 4,5′,8-trimethylpsoralen.
