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).

Antigenotoxic activity of naturally occurring furanocoumarins

Environmental and Molecular Mutagenesis, 2011
This study was designed to investigate the antigenotoxic effects of a series of naturally occurring furanocoumarins (NOFs) including isoimperatorin, imperatorin, (+)-oxypeucedanin, (+)-byakangelicol, and (+)-byakangelicine on antigenotoxic activities against genotoxicity induced by carcinogens [furylfuramide and N-methyl-N'-nitro-N-nitrosoguanidine ...

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.

Quantitative Recovery of Furanocoumarins fromPsoralea bituminosa

Phytochemical Analysis, 1997
The occurrence of bound coumarin derivatives in the Fabaceae has already been demonstrated. In an attempt to determine the yield of furanocoumarins following exhaustive recovery from Psoralea bituminosa, three different hydrolytic procedures have been employed. Method 1 involved the methanolic extraction of plant material followed by acid hydrolysis of

The Role of Dihydropsoralen in Furanocoumarin Metabolism

Canadian Journal of Biochemistry, 1973
Trapping experiments with [2-14C]umbelliferone and 2′,3′-dihydropsoralen (DHP) administered to Ruta graveolens yielded negative results over metabolic periods of 5–24 h. Specific radioactivities of psoralen were comparable to those previously observed, but those of DHP were about two orders of magnitude lower.

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.

Insect Antifeedant Furanocoumarins from Tetradium daniellii.

ChemInform, 2003
The dried fruits of Tetradium daniellii yielded a new linear furanocoumarin, 5-(6-hydroxy-3,7-dimethylocta-2,7-dienyloxy)psoralen, together with six other structurally related furanocoumarins. A similar chemical profile was recorded by HPLC analysis of a fragment of T.

[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).
