Furanocoumarins from the root ofAngelica dahurica

Archives of Pharmacal Research, 2000
Five furanocoumarins including a new one were isolated from the root of Angelica dahurica by repeated silica gel column chromatography. Their chemical structures were determined to be isoimperatorin (1), oxypeucedanin hydrate-3"-butyl ether (2), imperatorin (3), knidilin (4), and oxypeucedanin hydrate (5).

New furanocoumarins detected from grapefruit juice retentate

Natural Product Research, 2009
Grapefruit (Citrus paradisi Macf.) furanocoumarins and related compounds have been shown to interact with the enterocyte cytochrome P450, CYP3A4, and as a result they affect the bioavailibility of certain drugs. Only a few grapefruit furanocoumarins have been identified so far.

Evaluation of furanocoumarins from seeds of the wild parsnip (Pastinaca sativa L. s.l.).

Journal of chromatography. B, Analytical technologies in the biomedical and life sciences, 2019
Although the wild parsnip (Pastinaca sativa L. s.l.) fruits are known to contain linear and angular furanocoumarins, the individual components of the seeds have not been fully identified and quantitated, and, in the case of immature seeds, reported.

Bioactive furanocoumarins from stems of Clausena lansium

Phytochemistry, 2014
Clausena lansium Skeels, a member of the Rutaceae, is a shrub or small tree with grapelike fruits. Several parts of this plant have been used in folk medicine. A bioactive constituent investigation of the stems of C. lansium herein resulted in isolation of four furanocoumarins, claucoumarins A-D, and 13 known analogs.

Distribution of Furanocoumarins in Grapefruit Juice Fractions

Journal of Agricultural and Food Chemistry, 2005
The reported effects of grapefruit (Citrus paradisi Macf.) juice on oral bioavailability of certain prescription drugs have led to the discovery of the inhibition by compounds in grapefruit of cytochrome P450 3A4 (CYP3A4) in the intestinal wall and liver.

[Photobiophysics of furanocoumarins].

Biofizika, 2004
Furocoumarins (psoralens) are photosensitizers of plant origin, which increase the sensitivity of biological objects to near ultraviolet (UV-A, 320-400 nm). In combination with UV-A, they are successfully used for treating many dermal and autoimmune diseases (PUVA therapy and photophoresis).

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.

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 ...
