Solubilization of Eucalyptus citriodora essential oil and citronellal in deep eutectic solvents:water:cyclodextrins mixtures

چکیده
Essential oils (EOs) offer interesting biological properties that can be altered by their high volatility and low solubility. This study examined, for the first time, effect of combination different choline chloride (ChCl) based-deep eutectic solvents (DESs), water cyclodextrins (CDs) on retention solubilization Eucalyptus citriodora EO its major component, citronellal. The density, viscosity polarity newly prepared DES:water:CD mixtures were measured. influence content, DES type composition as well CD concentration capacity investigated using static headspace-gas chromatography. Results showed mixture composed chloride:urea (ChCl:U) (1:2 molar ratio) DES:water (70:30 wt%) in presence presented highest capacity. Finally, formation constant (Kf) values CD/citronellal inclusion complexes vapor-liquid partition coefficients citronellal determined ChCl:U 70:30 wt%.

Evaluation of Eucalyptus citriodora essential oil on goat gastrointestinal nematodes.
Phytotherapy may be an alternative strategy for controlling gastrointestinal parasites. This study evaluated the anthelmintic efficacy of Eucalyptus citriodora essential oil (EcEO). The in vitro effects of EcEO were determined through testing the inhibition of egg hatching and larval development of Haemonchus contortus. EcEO was subjected to acute toxicity testing on mice, orally and intraperit...
متن کاملChemical composition and inhibitory activity of essential oil from decaying leaves of Eucalyptus citriodora.
A study was undertaken to explore the content and composition of volatile oil from decaying leaves of lemon-scented eucalypt (Eucalyptus citriodora Hook.) not analyzed earlier. GC and GC-MS analysis of the oil (yield 0.6%) revealed the monoterpenoid nature with citronellal (52.2%), citronellol (12.3%) and isoisopulegol (11.9%) as the major constituents. Overall, 17 components were identified th...
متن کاملChemical composition and phytotoxicity of volatile essential oil from intact and fallen leaves of Eucalyptus citriodora.
A total of 23 volatile constituents was identified and characterized by GC and GC-MS in the volatile essential oil extracted from intact (juvenile and adult) and fallen (senescent and leaf litter) leaves of lemon-scented eucalyptus (Eucalyptus citriodora Hook.). The leaves differed in their pigment, water and protein content, and C/N ratio. The oils were, in general, monoterpenoid in nature wit...
متن کاملChanges in essential oil during enzyme-assisted ensiling of lemongrass (Cymbopogon citratus Stapf.) and lemon eucalyptus (Eucalyptus citriodora Hook).
Changes in essential oil during ensiling of lemongrass and lemon eucalyptus were studied. Wilted lemongrass and eucalyptus leaves were ensiled in 0.25-L anaerobic jars. Samples consisted of a control (no additives) and a treated sample (0.5% glucose and lactic acid bacteria and 1% cellulase plus 1% hemicellulase plus pectinase). Three jars per treatment were sampled on days 2, 6, 10, and 36 for...
متن کاملFungicidal Effect of Volatile Oils from Eucalyptus Citriodora and Its Major Constituent Citronellal
A study was undertaken to explore the effect of volatile oils from Eucalyptus citriodora and its major constituent citronellal against two well-known rice pathogens, Rhizoctonia solani and Helminthosporium oryzae. The radial growth and dry weight of both the test fungi were drastically reduced in response to the volatile oils. A complete inhibition of R. solani and H. oryzae was observed at 10 ...
