Preparative isolation of antioxidative furanocoumarins from Dracocephalum heterophyllum and their potential action target.

Journal of Separation Science, 2022
Traditional Tibetan medicine has extensively documented the health benefits of Dracocephalum heterophyllum. However, there are few reports on the chemical composition of furanocoumarins, probably because of their complicated isolation and purification ...

Simultaneous separation and determination of six furanocoumarins in Radix Angelicae dahuricae by CZE with dual CDs system.

Analytical Biochemistry, 2022
A novel, simple and efficient capillary electrophoresis method was developed to simultaneous determination of six furanocoumarins (psoralen, isopsoralen, imperatorin, isoimperatorin, phellopterin, and cnidilin).

Furanocoumarins from Dorstenia gigas

Phytochemistry, 2001
A series of linear and angular prenylated furanocoumarins and a benzofuran derivative were isolated from leaves and twigs of Dorstenia gigas (Moraceae), a plant occurring endemically on Socotra Island (Yemen). The structures were elucidated by spectroscopic methods (NMR, MS, UV) and chemical derivatization.

Biosynthesis of linear furanocoumarins

Canadian Journal of Biochemistry, 1970
Labelling experiments with 14C and 3H have shown that linear furanocoumarins of Ammi majus, Angelica archangelica, Heracleum lanatum (Umbelliferae), and Ruta graveolens (Rutaceae) are formed from umbelliferone via the dihydrofuranocoumarin, marmesin.

Isopimpinellin, a furanocoumarin

Journal of Crystal and Molecular Structure, 1977
Isopimpinellin (5,8-dimethoxypsoralen), C13H10O5, is a furanocoumarin isolated from the leaves and stems ofA pium australe Thouars. (Umbelliferae) collected near Concepcion, Chile. Extracts of the plant show activity against P-388 lymphocytic leukemia.

O-methyltransferases of furanocoumarin biosynthesis

Archives of Biochemistry and Biophysics, 1978
Extracts of the furanocoumarin-synthesizing plants, Ruta graveolens L. and Heracleum lanatum Michx., contain a soluble O-methyltransferase system mediating the methylation of the 5- and 8-hydroxyls of linear furanocoumarins by S-adenosyl- l -methionine.
