Effects of plant density on essential oil composition of sweet basil (Ocimum basilicum L.) cultivated in Turkey

Basil (Ocimum basilicum L., fam. Lamiaceae) is an important medicinal and aromatic plant with very wide range of uses. This paper presents qualitative and quantitative analyses of essential oils obtained from five types of Italian basil cultivars: Napolitan, Red basil, Fino Verde, Limonez, and Genoveze culltivated in Albania and collected during the summer 2012. The hydrodistilled BEO (Basil essential oil) content ranged from 0.11% to 3.40%. Within the total of 65 identified compounds with GC/FID/MS, nine were considered as predominant (1,8-cineole, linalool, cis-thujone, methyl chavicol, eugenol, trans-(E)-caryophyllene, trans-(α)-bergamotene, germacrene D, and epi-α-cadinol) representing 49.20 to 85.43% of the components in the analysed essential oils. In all cultivars, linalool was detected as the most abundant component (36.20-46.59%). BEO’s from all five cultivars differ in their chemical composition but generally conform to EO’s from Sweet Basil grown in the Medditeranean region. The Napolitan cultivar showed the largest similarity to Sweet Basil, not only for the morphology, also due to the essential oil composition that comprises Basil’s most dominant chemical components (linalool, methyl chavicol and eucalyptol) in particular percents.

Abiotic And Biotic Factors

Ocimum basilicum L., popularly known as sweet basil, is a Lamiaceae species whose essential oil is mainly composed of monoterpenes, sesquiterpenes and phenylpropanoids. The contents of these compounds can be affected by abiotic and biotic factors such as infections caused by viruses. The main goal of this research was an investigation of the effects of viral infection on the essential oil profile of common basil. Seeds of O. basilicum L. cv. Genovese were sowed and kept in a greenhouse. Plants presenting two pairs of leaves above the cotyledons were inoculated with an unidentified virus isolated from a field plant showing chlorotic yellow spots and foliar deformation. Essential oils of healthy and infected plants were extracted by hydrodistillation and analyzed by GCMS. Changes in essential oil composition due to viral infection were observed. Methyleugenol and p-cresol,2,6-di- tert-butyl were the main constituents. However, methyleugenol contents were significantly decreased in infected plants.

Basil Oil

The focus of the present study was on the influence of season on yield, chemical composition, antioxidant and antifungal activities of Omani basil ( Ocimum basilicum) oil. The present study involved only one of the eight Omani basil varieties. The hydro-distilled essential oil yields were computed to be 0.1%, 0.3% and 0.1% in the winter, spring and summer seasons, respectively. The major components identified were L- linalool (26.5 - 56.3%), geraniol (12.1 - 16.5%), 1,8-cineole (2.5 - 15.1%), ρ-allylanisole (0.2 - 13.8%) and DL-limonene (0.2 -10.4%). A noteworthy extra component was β- farnesene, which was exclusively detected in the oil extracted during winter and spring at 6.3% and 5.8%, respectively. The essential oil composition over the different seasons was quite idiosyncratic, in which the principal components of one season were either trivial or totally absent in another. The essential oil extracted in spring exhibited the highest antioxidant activity (except DPPH scavenging ability) in comparison with the oils from other seasons. The basil oil was tested against pathogenic fungi viz. Aspergillus niger, A. fumigatus, Penicillium italicum and Rhizopus stolonifer using a disc diffusion method, and by determination of minimum inhibitory concentration. Surprisingly high antifungal values were found highlighting the potential of Omani basil as a preservative in the food and medical industries.
