Inactivation ofEscherichia coliby citral [PDF]
Journal of Applied Microbiology, 2010 Aims: The aim was to evaluate (i) the resistance of Escherichia coli BJ4 to citral in a buffer system as a function of citral concentration, treatment medium pH, storage time and initial inoculum size, (ii) the role of the sigma factor RpoS on citral ...

MECHANISMS OF CITRAL PHOTOTOXICITY
Photochemistry and Photobiology, 1992Abstract—Citral, a monoterpene aldehyde synthesized by several plant genera, has been reported to exhibit antimicrobial activity. For the first time, we report that citral exhibits UV‐A (315–400 nm) light enhanced oxygen‐dependent toxicity against a series of Escherichia coli strains differing in DNA repair and catalase proficiency. Those E.

The antimicrobial activity of citral
Experientia, 1971Bestatigung fruherer Feststellungen, dass Citral eine antibakterielle Aktivitat besitzt. Da Neral und Geranial (allein oder zusammen) jedoch wesentlich weniger aktiv sind, muss fur die Citralaktivitat eine bisher nicht identifizierte Substanz verantwortlich sein.

Tetrahedron, 1963
Abstract Citral (I) is cyclized by UV irradiation 1 to 2-isopropenyl-5-methylcyclopentane-carboxaldehyde (II), containing the carbon skeleton of the monoterpenes of ants and catmint. 1,6,6-Trimethylbicyclo[2,1,1]hexane-2α-carboxaldehyde (XII, R = H), produced in lesser amount at the same time, was synthesized from camphor.

Conformational equilibria of citral
Journal of Molecular Structure: THEOCHEM, 2007Abstract The conformational behavior of citral was examined by NMR spectroscopy and DFT calculations wherein s - trans conformations were found to dominate over s - cis conformations based on temperature-dependent vicinal and through-space couplings and the calculations.

Biosynthetic relationship of citral-trans and citral-cis in cymbopogon flexuosus (lemongrass)
Phytochemistry, 1985Abstract Use of [ 14 C, 3 H]-labelled precursors revealed that leaf blades of Cymbopogon flexuosus converted geraniol (3,7-dimethylocta- trans -2,6-diene-1-ol) into citral- trans with loss of pro-(1 S ) hydrogen whereas nerol lost the pro-(1 R ) hydrogen while being converted into citral- cis . Secondly, the citral- trans is converted into citral-

Cyclodimerization of a citral dienamine
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1991The dienamine (a mixture of isomers) obtained from citral and diethylamine is converted to a mixture of citral anhydro cyclodimers by the action of weak proton-donor agents. The principal reaction product corresponds to [4 + 2]-cycloaddition of 1-diethylamino-7-methyl-3-methylene-1,6-octadiene (the minor component in the starting dienamine) to the ...
