Influence of Acid and Salt Sprays on Furanocoumarin Concentrations on the Ruta graveolens Leaf Surface

Volatile components of ripe fruits of Morinda citrifolia and their effects on Drosophila

“…Of the other compounds identified, an interesting one is scopoletin. As for other coumarins, the production of this phytoalexin has been associated with stresses, especially those linked to fungi [27][28][29]/Different environmental chemicals, acids or aldehydes, saturated or not, have been implicated in the induction of scopoletin production [30,31]. The high quantity of scopoletin found in Morinda might be related to the large amount of alkanoic acids also present.…”

Molecular evolution of parsnip (Pastinaca sativa) membrane‐bound prenyltransferases for linear and/or angular furanocoumarin biosynthesis

“…These molecules have important ecological functions: in addition to repulsive and toxic activities against certain insect larvae (Beier & Oertli, 1983;Beier, 1990;Miyazawa et al, 2004), linear FCs display phototoxic activities towards DNA upon exposure to ultraviolet (UV) radiation (Dall'Acqua et al, 1978;Kitamura et al, 2005). These phototoxic molecules have primarily been detected in the aerial parts of plants exposed to light (Zobel et al, 1991(Zobel et al, , 1994Milesi et al, 2001) but have also been detected in the roots (Milesi et al, 2001) and, in some cases, the seeds (Zobel & Brown, 1991a,b). The storage of FC in either the reproductive organs or the parts of the plant that are most exposed to predation might reflect an evolutionary mechanism that is based on the optimal defence theory (Zangerl & Rutledge, 1996;Wittstock & Gershenzon, 2002).…”

Analytical Methods for Isolation, Separation and Identification of Selected Furanocoumarins in Plant Material

“…Concentrations of linear furanocoumarins increase dramatically with plant age between 8 and 18 weeks (Reitz et al, 1997) with a subsequent decline in bergapten concentrations in the last six to eight weeks before harvest (Trumble et al, 1992). Significant decreases in levels of furanocoumarins were also observed both in and on senescing leaves of Ruta graveolens (Zobel & Brown, 1991). The content of some furanocoumarins in Apium graveolens and Petroselinum sativum decreases in summer and in autumn increases (Kohlmünzer, 2010).…”
