Orange peel extract solution contains mucilage flavor and three types of glycosides. Limonene is one of the terpenoides in some vegetables, fruits and food; that plays as an antioxidant in juice. As it has anti-microorganism effects on some bacteria, we carried out the antifungal effects of limonene versus orange extract. In the present study the effects of orange extract and two types of limon...

Perilla frutescens var. crispa (Labiatae) has two chemo-varietal forms, i.e. red and green forms of perilla, that differ in the production of anthocyanins. To facilitate molecular biological and biochemical studies in perilla-specialized metabolism we used Illumina RNA-sequencing technology in our comprehensive comparison of the transcriptome map of the leaves of red and green forms of perilla....

The toluene-degrading strain Rhodococcus opacus PWD4 was found to hydroxylate D-limonene exclusively in the 6-position, yielding enantiomerically pure (+) trans-carveol and traces of (+) carvone. This biotransformation was studied using cells cultivated in chemostat culture with toluene as a carbon and energy source. The maximal specific activity of (+) trans-carveol formation was 14.7 U (g of ...

Rice stink bug (RSB), Oebalus pugnax F., is an important pest of heading rice in the United States. Little is known about plant volatiles production following herbivory by rice stink bug. RSB feeding induced volatiles production in different RSB host grasses and rice varieties, and may help explain RSB movement to heading rice. Limonene and methyl salicylate (MeSA) were found in varying amounts...

The Lippia alba (Mill.) N.E. Brown (Verbenaceae) species, has effects sedative, analgesic and spasmolytic properties. This study had as its main objective to evaluate the essential oil of L. alba (EOLa) effect and that of its main constituents, citral and limonene, over tracheal smooth muscle from Wistar rats. EOLa, citral and limonene promoted relaxation of tracheal smooth muscle in contractio...

Menthofuran rich eight half-sib seed progeny of Mentha piperita (MPS-36) were studied for various genetic parameters, namely, coefficient of variation, heritability, genetic advance, correlation, and path of various plant and oil attributes, namely, plant height, L:S ratio, herb yield, β -myrcene, limonene, 1,8-cineole, menthone, menthofuran, neomenthone, pulegone, and menthol. Maximum genotypi...

The cultivated strawberry ( Fragaria × ananassa ) is an economically important fruit crop that intensively bred for improved sensory qualities. diversity of flavors and aromas in results mainly from the interactions sugars, acids, volatile organic compounds (VOCs) are derived diverse biochemical pathways influenced by expression many genes. This study integrates multiomic analyses to identify Q...

Abstract Haplophyllum tuberculatum is a plant commonly used in folk medicine to treat several diseases including vomiting, nausea, infections, rheumatism, and gastric pains. In the current study, H. essential oils, hydrosols, pure compounds R-(+)-limonene, S-(−)-limonene, 1-octanol, as well their combinations R-(+)-limonene/1-octanol S-(−)-limonene/1-octanol, were screened for cytotoxicity on H...

In this study, an ultrasound-aided hydrothermal-impregnation method was used to synthesize three-dimensional (3D) urchin-like CdS-TiO2 nanostructures (UCTs) with variable CdS content. The photocatalytic efficiencies (for degrading limonene and toluene vapor) of UCTs synthesized using the ultrasound-aided process were greater than those of UCTs fabricated without ultrasound treatment. In additio...
