“…Previously, many authors reported that acetone extracts of various plants have highest larvicidal and adulticidal activity against mosquito 23,24 . The results obtained from Table 4 confirms the facts that had been established by previous works in terms of efficacy of the active ingredient in Cymbopogon citratus 18,19,20,21 . From the experimental result, it was clearly confirmed that the essential oil in Cymbopogon citratus extract repels mosquitoes at different concentrations.…”

ABSTRACT:The main objective of the work was to extract the active ingredient in Cymbopogon citratus leave and to formulate a mosquito repellent cream naturally obtained from medicinal plants instead of commonly available synthetic repellents and insecticides such as N-Diethyl-3methylbenzamide (DEET), which are carcinogenic and non eco-friendly. The formulation of cream have smooth texture with a pH 7.30 which is non-irritant and suitable for the skin.

“…This increase of efficacy could be attributed to synergism or addition effect of antibacterial compounds of the EOs combined. Some study has reported that mixture of EOs showed interaction activity with each other acting as additive, synergistic and in a few cases antagonistic agents (Gutierrez et al, 2009;Bassolé et al, 2010;Bassolé et al, 2011). The restriction of combined EOs activities to Salmonella typhimurium and Salmonella paratyphimurium and its recurrent bactericidal activities to same strains sensitive to Cymbopogon citratus can be due to the fact that the whole combination activity may be influenced by the presence of Cymbopogon citratus EO for each one.…”

“…It has been explained that essential oils combination has the advantage to have the effect at many sites of action on bacterial cells with several mechanisms of action. It therefore result an increase of the effect and a limitation of the phenomenon of resistance (Bassolé et al, 2010;Bassolé et al, 2011).…”

Background: In Cameroon, one of the most common childhood illnesses after malaria is diarrhea, which generally has a bacterial origin. In rural areas, plant utilization is often one of the first ways of treatment though, with no scientific bases. Therefore, the aim of this work was to evaluate the antibacterial activities of nine essential oils (EOs) of Cameroonian plants and their combinations against some strains responsible for diarrhea. Material and Methods:To determine the bacterial species generally involved in childhood diarrheal infections, a retrospective study was done. The EOs of Eucalyptus globulus, Cymbopogon citratus, Xylopia aethiopica, Thymus vulgaris, Ocimum canum, Cananga odorata, Citrus medica, Citrus paradisi and Citrus reticulata were screened against the most incriminated bacterial species using the spot-on-agar test and microdilution methods. Some of the EOs with good antibacterial activity were analyzed by Gas Chromatography and Gas Chromatography/Mass Spectrometry. According to their composition, Thymus vulgaris and Eucalyptus globulus EOs were combined with that of Cymbopogon citratus using the ratios 2/1; 1/1; 1/2 (w/w) and tested against on bacterial growth. Results: The retrospective study showed that 10.8% of infant diarrhea was caused by Escherichia coli, Salmonella typhimurium and Salmonella paratyphimurium. The Minimum inhibition Concentrations (MIC) of single EOs was between 0.78 and 25 mg/mL which were observed to be greater than those of their combinations which ranged between 0.195 and 6.52 mg/mL. The active essential oils contained mainly hydrocarbonated and oxygenated monoterpens. Conclusion: The good antibacterial effects of two Thymus combinations Th 1 and Th 2 observed on Salmonella typhimurium and Salmonella paratyphimurium suggest their used in aromatherapy to cure bacterial diarrhea.

“…This result may be due to the high concentration of citral in lemongrass, about 70-85% (BASSOLÉ et al, 2011), which caused burning on the petals that received this treatment. Citral is a mixture of isomers with an aroma characteristic of lemon in which its fungicidal action stands out, among its biological properties.…”

The loss of commercial quality during storage and transportation of roses is one of the factors that reflect on production costs, leading producers to preventively apply harmful chemicals, mainly to hamper Botrytis cinerea development and reduce further losses. An alternative to increase flower longevity without contaminating the environment with harmful chemicals is the use of natural products, such as essential oils, which have fungistatic and insecticide properties, as well as low toxicity. The objective of this study was to evaluate the effect of essential oils on the vase life of Rosa cv. Avalanche: 12 treatments were tested, resulting from the combination of 5 types of essential oils plus the control in two cold storage periods (2 to 6 days) at 1 °C, 90-95% RH. The essential oils tested were eucalyptus, cinnamon, lemongrass and peppermint (1%), clove (0.1%), plus a control with distilled water. Application was made by spraying the flower buds. After storage at low temperatures, the flower stems were kept in a room (16 °C, 70% RH) during 10 days for evaluation. Flower stems stored for 2 days in a cold chamber showed better means for darkening, turgor and bent neck, as well as a lower weight loss by the stems. The application of lemongrass essential oil at 1% caused burns on the petals, compromising quality and pot life. The essential oils of peppermint and eucalyptus allowed flower quality maintenance until the 10th day of evaluation. It is possible to conclude that post-harvest spraying with peppermint or eucalyptus essential oil at 1%, combined with cold storage for 2 days, provided greater longevity and quality for cv. Avalanche roses. Keywords: Rosa sp., alternative control, cold storage, natural products, RESUMO Qualidade pós-colheita de rosas tratadas com óleos essenciaisA perda da qualidade comercial de rosas durante o armazenamento pós-colheita e transporte é um dos fatores que mais oneram o custo de produção e leva os produtores a realizar a aplicação preventiva de produtos químicos nocivos, principalmente para evitar o aparecimento de lesões do fungo Botrytis cinerea. Uma das alternativas para aumentar a durabilidade das flores de forma ecologicamente correta é a utilização de produtos naturais, como os óleos essenciais, que apresentam características fungistáticas e inseticidas, além de baixa toxicidade. O objetivo deste trabalho foi avaliar o efeito da aplicação em pós-colheita de diferentes óleos essenciais na durabilidade de hastes de Rosa cv. Avalanche em 2 períodos de armazenamento em câmara fria. Foram testados 12 tratamentos resultantes da combinação de 5 tipos de óleos essenciais mais a testemunha associados à dois períodos de armazenamento refrigerado, 2 e 6 dias, sob 1 ºC e 90-95% UR. Foram testados óleos essenciais de: eucalipto, canela, capimlimão e hortelã-pimenta (a 1%), cravo-da-índia (a 0,1%), e a testemunha, com água destilada. A aplicação foi feita por meio da pulverização nos botões florais. Após o armazenamento refrigerado, as hastes florais foram mantidas em uma sala ...
