“…The essential oil constituents were identified by the comparison of their GC retention indices (RI) and mass spectra with those of the authentic standard compounds. Quantification of the relative amounts of the individual components was performed according to the area percentage method (Telci et al 2006) for each plant.…”

Saha S., Dhar T.N., Sengupta C., Ghosh P.D. (2013): Biological activities of essential oils and methanol extracts of five Ocimum species against pathogenic bacteria. Czech J. Food Sci., 31: 194-202.The essential oils and methanol extracts of Ocimum basilicum L., Ocimum kilimandscharicum Guerke, Ocimum gratissimum L, Ocimum canum Sims, and Ocimum tenuiflorum L. (green type) were examined for their potential antibacterial activities. The chemical composition of essential oils of Ocimum species was analysed by GC-MS. The inhibitory effects of essential oils and methanol extracts were studied on two Gram-positive (Bacillus subtilis, Micrococcus luteus) and five Gram-negative (pseudomonas aeruginosa, Shigella dysenteriae, escherichia coli, Vibrio cholera, and Shigella flexneri) bacteria using disc-diffusion method. Minimum inhibitory concentration (MIC) was assessed by micro broth dilution method. The antibacterial test results showed that the essential oils of Ocimum basilicum L., Ocimum kilimandscharicum Guerke, and Ocimum gratissimum L. strongly inhibited the growth of all of the microorganisms studied, especially of the Gram-negative strains, whereas other two essential oils showed moderate activities. The result may suggest that the essential oils of Ocimum possess compounds with antibacterial activities, and therefore could be used as natural preservative ingredients in food and/or pharmaceutical industries.

“…Among more than 150 species of the genus Ocimum, basil is the major essential oil crop which is cultivated commercially in many countries (Sajjadi, 2006). Traditionally, basil has been extensively utilized in food as a flavoring agent, and in perfumery and medical industries (Telci, et al 2006). The leaves and flowering tops of the plant are perceived as carminative, galactogogue, stomachic and antispasmodic in folk medicine (Sajjadi, 2006).…”

The present research was carried out during winter and spring growing seasons of 2014 for controlling the aphid attacking the cultivated cucumber in greenhouse. In the spring season of 2014, azadirachtin was evaluated against the aphid and compare with the tested essential oils, while in the winter season azadirachtin was compared with two insecticides (abamectin and pyrethrin). Metalaxyl as a fungicide was applied during the both growing seasons as a protective agent against the downy mildew. The results showed that onion oil and red basil oil were the most effective treatments throughout the test period of spring season in reducing the number of aphid giving the highest general mean of reduction percentages, 73.8%, 68.85%, respectively, but in winter season, azadirachtin and abamectin were the most effective treatment throughout the test period in reducing the number of aphid giving the same highest general mean of residual reduction percentage (74.17% and 74.15%), respectively, while Pyrethrin showed a reduction of 72.40%. The residues of the applied pesticides, were determined in the collected samples of commercial and experimental cucumber fruits. The results showed that the detected amount of carbohydrates; potassium and vitamin C were high in the sample of experimental cucumber fruits (prince variety), where the lower detected ones were recorded in commercial cucumber fruits (mixed varieties). Moreover, it was found that commercial cucumber fruits contained higher amount of the pesticide residues of propamocarb (a carbamate fungicide) (0.53 ppm) and iprodione (a carbamate fungicide) (0.19 ppm) which are greatly dangerous to human health. It is noticed that the Egyptian farmers are using so much pesticides and therefore, it is important to advise the farmers about the type of pesticides and the rate they are applying via safe recommendations.

RESUMO -O gênero Croton L., pertence à família Euphorbiaceae presente no bioma Caatinga do Nordeste brasileiro. O estudo objetivou avaliar a infl uência do ciclo circadiano e da sazonalidade no rendimento e na composição química dos óleos essenciais de Croton blanchetianus Baill., Croton nepetifolius Baill. e Croton zehntneri Pax & K. Hoff m. Para estudo do ciclo circadiano, as folhas foram coletadas no horário de 8, 12 e 20h e para a sazonalidade as coletas foram realizadas no horário de 8h. O ciclo circadiano e a sazonalidade infl uenciaram o rendimento apenas de C. zehntneri, indicando maior rendimento na colheita às 12 horas e na estação seca. A composição química das espécies estudadas foi infl uenciada pelo ciclo circadiano e a sazonalidade, constatando-se que determinados compostos só são produzidos em horários e estações específi cas. Portanto, os fatores ambientais estudados interferem no rendimento e composição química dos óleos essenciais das espécies de Croton spp. To study the circadian cycle, the leaves were collected at 8:00, 12:00 and 20:00 and for the seasonal collections they were carried out at 8h. The circadian cycle and seasonality only infl uenced the yield of C. zehntneri, indicating a greater yield in harvest at 12:00 and in the dry season. Chemical compositions of C. blanchetianus, C. nepetifolius and C. zehntneri oils were infl uenced by the circadian cycle and seasonality demonstrating that certain compounds are only produced at specifi c times and seasons. Therefore, the studied environmental factors aff ect the yield and chemical composition of essential oils of species of Croton. Palavras
