“…Sacchetti et al (2005) [28] reported the presence of 65 to 86% citral in the EO of this species. In more recent studies, Lucena et al (2015) [29] found levels of neral 43.69% and 34.05% geranial, and Gonçalves et al (2015) [9] reported the presence of geranial (46.32%) and neral (31.28%) values similar to those found in OE C. citratus analysis in this study.…”

The study evaluated the chemical profile, antimicrobial activity and toxicity of essential oils (EOs) of C. citratus, O. basilicum and A. rosaeodora. The EOs were extracted by hydrodistillation, the chemical profile was determined using the physicochemical parameters and the chemical composition was obtained by gas chromatography coupled to mass spectrometry (GC-MS). The toxicity assay followed the Artemia salina Leach bioassay. To perform the antimicrobial activity, the Disc Diffusion technique and the Mueller Hinton Broth Dilution (MH) technique were used. The physicochemical parameters of the EOs showed satisfactory results. The major chemical composition of the EO of A. rosaeodora presented linalool (93.60%), the EO of C. citratus exhibited geranial (43.96%) and EO of O. basilicum found methyl chavicol. All EOs in this study had LC50 between 582 mg L-1 and 282 mg L-1. The antimicrobial activity of EO C. citratus demonstrated inhibition halos for S. aureus of 25 mm and 25 mm for E. coli, EO of O. basilicum exhibited inhibition halo of 18 mm for E.coli and 20 mm for S. aureus and EO of A. rosaeodora presented 11 mm for E. coli and 15 for S. aureus. As the values of MIC and MBC found, the EO of O. basilicum presented a more effective inhibitory action against S. aureus. It was concluded that the observed biological potentials encourage the application potentials in the efficiency of the control of pathogenic microorganisms.

“…Popular medicine uses its tea or muffled, prepared from its leaves such as soothing, analgesic, antipyretic, antirheumatic, diuretic and digestive disorders. Through studies it is possible to attribute antimicrobial activity to the geranial and neral major compounds present in their EO [9].…”

“…Elevated levels of Geranial and Neral in the chemical composition of lemongrass were observed by [22], with a mean of approximately 51% and 36%, respectively. The authors [23] also observed similar percentages for Geranial (46.3%) and Neral (31.28%). Yet [24] found levels of 43.6% for Neral and 34% for Geranial, values that are different to the ones found on this work, where the highest percentage was of Neral.…”

Essential Oil of Cymbopogon citratus on the Control of the Curvularia Leaf Spot Disease on Maize

et al. 2017

The Curvularia Leaf Spot is becoming more common due to the culture expansion and the low resistance of the cultivated genotypes in tropical regions. Thus, the objective was to evaluate the fungitoxicity of the essential oil of Cymbopogon citratus upon the phytopathogen Curvularia lunata, causative agent of the Curvularia Leaf Spot. There was realized pathogenicity tests of C. lunata in maize plants, phytotoxicity of the essential oil of C. citratus and gas chromatography attached, germination tests of the conidia, and of in vitro inhibition of C. lunata. Also, there were realized tests aiming at verifying the phytopathogen control in vivo. In the pathogenicity tests, there were verified symptoms of the disease in all of the suspensions tested on plants. It was observed that the essential oil concentrations of 7.5 µL mL−1 to 50 µL mL−1 were phytotoxic. The majoritarian chemical components of the essential oil of C. citratus were Geranial (41.46%) and Neral (32.43%). The concentrations of 5 and 7.5 µL mL−1 inhibited 100% of conidia germination. None of the concentrations evaluated effectively inhibited C. lunata mycelial growth in in vitro tests. In the preventive control, the concentration of 7.5 µL mL−1 was sufficient for the reduction of the progress of the disease, however the curative control was not efficient on the tested dosages.

“…The antifungal activity of citral, the major constituent of the essential oil of C. citratus, may cause rupture of the cell membrane integrity and extravasation of the cellular components of the microorganisms. In the present study, it was found that this constituent in particular was more effective than the essential oil itself, with absence of the mycelial growth of R. solani and S. rolfsii [21,22].…”

Aims: This study is aimed to evaluate the in vitro antifungal activity effect of the crude aqueous extract (CAE), hydrolate (HY) and essential oil (EO) of Corymbia citriodora, Cymbopogon citratus, Cymbopogon flexuosus and Curcuma longa against the phytopathogenic fungi Alternaria steviae, Botryosphaeria dothidea, Colletotrichum gloeosporioides and Sclerotium rolfsii, and assess, in situ, the effectiveness of CAE of medicinal plants in reducing the severity of the cucumber anthracnose. Methodology: The EOs and HYs were obtained by hydrodistillation. The CAEs were prepared by the turbolysis method. Mycelial growth of the fungi was measured daily, by the diametrically opposite method. In the in vivo test, the CAEs were sprayed on the cotyledon leaves of healthy cucumber plants with three days after were inoculated with C. lagenarium. The severity of assessment of the disease was based on a scale of notes. Results: The medicinal plants studied showed antifungal activity against all or almost all pathogens. In general, treatment with CAE and HY of C. longa revealed the highest inhibition against the fungi tested. With the exception of the EO of C. longa, the other EOs showed total inhibition against all the fungi and in all the concentrations tested. Compared to control, in in vivo assays CAE of C. citratus presents a potential for control of cucumber anthracnose reducing the severity of the disease. Conclusion: The medicinal plants studied produce compounds associated with antimicrobial activity.
