Coumarin formation has been studied with C14 in the perennial grass, Hierochloe odorata, and in yellow sweet clover, Melilotus officinalis. In general the latter species yielded inconsistent data. In Hierochloe, o-coumaric, cinnamic, and shikimic acids and L-phenylalanine were the best of 10 compounds tested as coumarin precursors, the first two at least being incorporated with little randomization of C14. Acetate was more poorly utilized. It was concluded that the aromatic ring of coumarin… Expand
Translocation of Coumarin Across a Graft Union in Sweetclover 1
TLDR
Data on the coumarin content of grafted sweetclover plants are presented and the significance of this information is discussed and the glycosides of o-hydroxycinnarnic acid, not molecular coumar in, are present in the intact plant. Expand
Chemistry and health effects of furanocoumarins in grapefruit.
TLDR
It is suggested furanocoumarins may serve as bioactive components that contribute, at least in part, to the health benefits of grapefruit. Expand
Biochemistry of The Coumarins
The coumarins are a group of lactones derived from benzopyrone. Since the discovery by Vogel over a century and a half ago of the simplest member of the class, coumarin itself (1), inDipteryxExpand
The 2-hydroxylation of trans-cinnamic acid by chloroplasts from Melilotus alba Desr.
TLDR
It was found that approximately 50% of the hydroxylase activity is bound to the lamellar membranes, from which it can be released by sonication. Expand
A 2-oxoglutarate-dependent dioxygenase from Ruta graveolens L. exhibits p-coumaroyl CoA 2'-hydroxylase activity (C2'H): a missing step in the synthesis of umbelliferone in plants.
TLDR
Its bi-functionality was further confirmed in planta: transient expression of JF799117 in Nicotiana benthamiana yielded plants with leaves containing high levels of umbelliferone and scopoletin when compared to control plants, which contained barely detectable traces of these compounds. Expand

TLDR
2-Oxoglutarate-dependent dioxygenases from plants convert cinnamate derivatives into simple coumarins through the process of ortho-hydroxylation, which describes the 2OGDs involved in coumarin biosynthesis and their substrate specificities. Expand
Identification and functional characterization of the first two aromatic prenyltransferases implicated in the biosynthesis of furanocoumarins and prenylated coumarins in two plant families: Rutaceae and Apiaceae
Furanocoumarins constitute one of the classes of secondary metabolites deriving from the phenylpropanoid biosynthetic pathway. These molecules are described as phytoalexins in plants but are alsoExpand
Biosynthesis of coumarins in plants: a major pathway still to be unravelled for cytochrome P450 enzymes
TLDR
This review highlights the major steps of the coumarin pathway with emphasis on the cytochrome P450 enzymes involved, including Ortho-hydroxylation of hydroxycinnamic acids, and the outcomes of novel strategies developed to uncover cou marin-committed CYPs. Expand
