The heterogeneously catalyzed selective-hydrogenation of citral is one of the more feasible ways for obtaining its appreciated unsaturated-alcohols, nerol and geraniol, which are present in over 250 essential oils. Thus, citral has very recently come to be produced petro-chemically in very large quantities, and so partial hydrogenation of citral has become a very economical route for the produc...

Citral, the main constituent of lemongrass (Cymbopogon citratus) essential oil, was added to Trypanosoma cruzi cultures grown in TAU3AAG medium to observe the effect on the epimastigote-to-trypomastigote differentiation process (metacyclogenesis). Our results showed that citral (20 μg/mL) did not affect epimastigote viability or inhibit the differentiation process. Concentrations higher than 60...

BACKGROUND The conversion of retinol (ROH) to retinoic acid (RA) is crucial during development but has been not studied during blastocyst formation. METHODS AND RESULTS In vitro-produced bovine morulae were treated for 24 h with citral (which inhibits the synthesis of RA from ROH), citral + all trans retinoic acid (ATRA), ATRA or no additives. Citral interfered with blastocyst development, wh...

Banana, papaya and pineapple are the most consumed tropical fruits in the world, being Brazil one of the main producers. Fungi Colletotrichum musae, Colletotrichum gloeosporioides and Fusarium subglutinans f.sp. ananas cause severe post harvest diseases and losses in fruits quality. The aim of this work was to evaluate the effectiveness of five monoterpenes to inhibit the mycelial growth and co...

The aim of the study was to characterize the chemical composition and biological properties of the essential oil from the plant Lippia citriodora grown in Greece. The essential oil volatiles were analyzed by gas chromatography-mass spectrometry GC-MS indicating citral as the major component. Τhe antimicrobial properties were assayed using the disk diffusion method and the minimum inhibitory and...

The present work aimed to evaluate the insecticidal activity of Cymbopogon citratus essential oil and its major compounds (citral myrcene) on Anticarsia gemmatalis. oil, citral, myrcene, a mixture citral myrcene were tested at concentrations 0.1, 0.3, 0.5, 0.7, 0.9 % v/v, plus two negative controls (distilled water Tween-80® 0.5 v/v) positive control (novaluron 0.075 w/v). Insect mortality was ...

Introduction: The aliphatic monoterpene 3, 7-dimethyl-2, 6-octadienal (Citral) is a flavour additive widely used in the cosmetic and food industries. It has been shown to have a negative impact on female fertility acting via hormone receptors. No data is available about the effects of Citral on the male reproductive system. Objective: This study was carried out to study the effects of Citral on...

Numerous plant compounds have antibacterial or antiviral properties; however, limited research has been conducted with nonenveloped viruses. The efficacies of allspice oil, lemongrass oil, and citral were evaluated against the nonenveloped murine norovirus (MNV), a human norovirus surrogate. The antiviral mechanisms of action were also examined using an RNase I protection assay, a host cell bin...

The behavioral response of Lasioderma serricorne adults to citronellal, citral, and rutin was investigated by using the area preference method. The L. serricorne adults were exposed to citronellal, and citral at the rate of 1:10, 1:50, 1:100 and 1:1000 (citronellal: ethanol, v/v) for 1, 2, 12 and 24 h, to rutin at the rate of 10, 30 and 90 g/m(2) for 1, 2, 12 and 24 h, respectively. The citrone...

The aim of the present study was to investigate the biological activity of 20 essential oils (EOs) derived from herbal plants and citrus fruits. The in vitro anti-allergic and anti-inflammatory activities of these oils were investigated, and the EO which was found to have the strongest activity of the 20 EOs examined, was investigated further to identify its components and bioactive compounds. ...
