biocontrol potential of methyl Chavicol for managing spodoptera frugiperda lepidoptera noctuidae an important corn pest
Environmental Science and Pollution Research, 2020Co-Authors: Claubert Wagner Guimaraes De Menezes, Geraldo Andrade Carvalho, Dejane Santos Alves, Alexandre Alves De Carvalho, Smail Aazza, Vinicius De Oliveira Ramos, Jose Eduardo Brasil Pereira Pinto, Suzan Kelly Vilela BertolucciAbstract:Synthetic insecticides applied to control Spodoptera frugiperda (Lepidoptera: Noctuidae) can have negative impacts on environment and human health. Botanical essential oils can be sources of organic molecules with biocontrol potential and advantages, such as minor impacts on the selection of resistant pest insects and low toxicity to humans. The aim of this study was to investigate the biocontrol action of essential oils from Brazilian species and methyl Chavicol compounds on the development and metabolism of S. frugiperda. Essential oils of Eremanthus erythropappus (Asteraceae), Ocimum selloi, Hyptis suaveolens, and Hyptis marrubioides (Lamiaceae) were distilled by the steam distillation method and analyzed by gas chromatograph techniques. The essential oils were incorporated into an artificial diet (at 1, 2, and 4 mg mL(-1)) and offered to S. frugiperda caterpillars. Larvae of S. frugiperda at 48 h of age were fed an artificial diet containing the major constituent of O. selloi (methyl Chavicol). The major compounds of the essential oils were methyl Chavicol for O. selloi, alpha-bisabolol for E. erythropappus, bicyclogermacrene for H. suaveolens, and beta-thujone for H. marrubioides. O. selloi caused 100% mortality in S. frugiperda larvae at a concentration of 1 mg mL(-1) after 48 h. H. marrubioides essential oil caused 100% mortality in larvae at a concentration of 4 mg mL(-1) after 48 h. O. selloi and H. marrubioides inhibited acetylcholinesterase (AchE) activity in 72.87% and 81.69% of larvae, respectively. O. selloi presented the highest toxicity to S. frugiperda and the lowest inhibition of AchE. Methyl Chavicol was lethal to all larvae within 24 h at a concentration of 0.92 mg mL(-1) of diet. Methyl Chavicol showed the best insecticidal activity and potential to be used as a natural insecticide to control S. frugiperda.

In vitro antifungal activity of Ocimum selloi essential oil and methylChavicol against phytopathogenic fungi
Revista Ciencia Agronomica, 2015Co-Authors: Larissa Corrêa Do Bomfim Costa, Péricles Barreto Alves, Jose Eduardo Brasil Pereira Pinto, Suzan Kelly Vilela Bertolucci, João De Cássia Do Bomfim Costa, Edenilson Dos Santos NiculauAbstract:The ef ficacy of Ocimum selloi essential oil was evaluated for controlling the growth of mycelia and spores germination Moniliophthora perniciosa. Six compounds (99.89%) of the total oil were identified by GC-MS, of which methyl Chavicol, methyl eugenol, �� -caryophyllene, germacrene-D, bicyclogermacrene and spathulenol. Essential oil was tested for anti- fungal activity, which was determined by disc diffusion and minimum inhibitory concentration (MIC) determination methods. Application of the oil reduced mycelial growth in a dose dependent manner, with maximum inhibition being observed at concentration of 1,000 ppm. Such antifungal activity could be attributed to methyl Chavicol since the pure compound was shown to be similarly effective against Moniliophthora perniciosa at 1,000 ppm. The oil when applied at a concentration of 1,000 ppm, reduced the spore germination of Colletotrichum gloeosporioides and M. perniciosa by 93 and 87%, respectively, but had no effect on the Alternaria alternata. It is concluded that the oil from O. selloi and its major constituent, methyl Chavicol, are efficient in inhibiting M. perniciosa, but less effective against C. gloeosporioides and A. alternata. The results obtained from this work may contribute to the development of alternative anti-fungal agents to protect the cacao crop from fungal disease.

methyl Chavicol characterization of its biogenic emission rate abundance and oxidation products in the atmosphere
Atmospheric Chemistry and Physics, 2008Co-Authors: N C Bouvierbrown, Allen H Goldstein, David R Worton, D M Matross, J B Gilman, W C Kuster, D Welshbon, C Warneke, J A De Gouw, Thomas M CahillAbstract:We report measurements of ambient atmospheric mixing ratios for methyl Chavicol and determine its biogenic emission rate. Methyl Chavicol, a biogenic oxygenated aro- matic compound, is abundant within and above Blodgett For- est, a ponderosa pine forest in the Sierra Nevada Mountains of California. Methyl Chavicol was detected simultaneously by three in-situ instruments - a gas chromatograph with mass spectrometer detector (GC-MS), a proton transfer reac- tion mass spectrometer (PTR-MS), and a thermal desorption aerosol GC-MS (TAG) - and found to be abundant within and above Blodgett Forest. Methyl Chavicol atmospheric mixing ratios are strongly correlated with 2-methyl-3-buten- 2-ol (MBO), a light- and temperature-dependent biogenic emission from the ponderosa pine trees at Blodgett Forest. Scaling from this correlation, methyl Chavicol emissions ac- count for 4-68% of the carbon mass emitted as MBO in the daytime, depending on the season. From this relation- ship, we estimate a daytime basal emission rate of 0.72- 10.2µgCg 1 h 1 , depending on needle age and seasonality. We also present the first observations of its oxidation prod- ucts (4-methoxybenzaldehyde and 4-methyoxy benzene ac- etaldehyde) in the ambient atmosphere. Methyl Chavicol is a major essential oil component of many plant species. This work suggests that methyl Chavicol plays a significant role in the atmospheric chemistry of Blodgett Forest, and potentially other sites, and should be included explicitly in both biogenic volatile organic carbon emission and atmospheric chemistry models.

Methyl Chavicol: characterization of its biogenic emission rate, abundance, and oxidation products in the atmosphere
Atmospheric Chemistry and Physics Discussions, 2008Co-Authors: N. C. Bouvier-brown, Allen H Goldstein, David R Worton, D M Matross, J B Gilman, W C Kuster, C Warneke, J A De Gouw, D. Welsh-bon, Thomas M CahillAbstract:Abstract. We report measurements of ambient atmospheric mixing ratios for methyl Chavicol and determine its biogenic emission rate. Methyl Chavicol, a biogenic oxygenated aromatic compound, is abundant within and above Blodgett Forest, a ponderosa pine forest in the Sierra Nevada Mountains of California.

secondary organic aerosol formation and composition from the photo oxidation of methyl Chavicol estragole
Atmospheric Chemistry and Physics, 2013Co-Authors: Kelly L Pereira, Jacqueline F Hamilton, A R Rickard, William J Bloss, Mohammed S Alam, M Camredon, Amalia Munoz, M Vazquez, Esther Borras, Milagros RodenasAbstract:Abstract. The increasing demand for palm oil for uses in biofuel and food products is leading to rapid expansion of oil palm agriculture. Methyl Chavicol (also known as estragole and 1-allyl-4-methoxybenzene) is an oxygenated biogenic volatile organic compound (VOC) that was recently identified as the main floral emission from an oil palm plantation in Malaysian Borneo. The emissions of methyl Chavicol observed may impact regional atmospheric chemistry, but little is known of its ability to form secondary organic aerosol (SOA). The photo-oxidation of methyl Chavicol was investigated at the European Photoreactor chamber as a part of the atmospheric chemistry of methyl Chavicol (ATMECH) project. Aerosol samples were collected using a particle into liquid sampler (PILS) and analysed offline using an extensive range of instruments including; high-performance liquid chromatography mass spectrometry (HPLC-ITMS), high-performance liquid chromatography quadrupole time-of-flight mass spectrometry (HPLC-QTOFMS) and Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS). The SOA yield was determined as 18 and 29% for an initial VOC mixing ratio of 212 and 460 ppbv (parts per billion by volume) respectively; using a VOC:NOx ratio of ~5:1. In total, 59 SOA compounds were observed and the structures of 10 compounds have been identified using high-resolution tandem mass spectrometry. The addition of hydroxyl and/or nitro-functional groups to the aromatic ring appears to be an important mechanistic pathway for aerosol formation. This results in the formation of compounds with both low volatility and high O:C ratios, where functionalisation rather than fragmentation is mainly observed as a result of the stability of the ring. The SOA species observed can be characterised as semi-volatile to low-volatility oxygenated organic aerosol (SVOOA and LVOOA) components and therefore may be important in aerosol formation and growth.

Antispasmodic effect of Ocimum selloi essential oil on the guinea-pig ileum
Natural Product Research, 2015Co-Authors: Sylvia D.f. Souza, Péricles Barreto Alves, Jose Eduardo Brasil Pereira Pinto, Carolina S.l. Franca, Edenilson Dos Santos Niculau, Larissa Corrêa Do Bomfim Costa, Rosilene M. MarçalAbstract:Ocimum selloi is an herbal species popularly used in Brazil as antispasmodic. Herein, we report the antispasmodic effect of O. selloi essential oil (OS) in segments of guinea-pig ileum. OS did not reduce the tonus of the ileum. In contrast, OS reduced the contraction induced by carbachol (100 μM), BaCl2 (0.03 M) and low- and high-K+ concentrations (25 and 60 mM, respectively). OS shifted the concentration–response curve for calcium to the right in a parallel manner. GC/MS analysis showed that OS consists mostly of methyl Chavicol (97.57%). These results suggest that OS antispasmodic effect is mediated through calcium channel blockade. In addition, OS effect and mode of action could be accounted for methyl Chavicol.
