“…This could be due to a number of factors including differences in agronomic conditions 14 , planting site or geographical locations 12,20 , season at the time of collection 10 , stage of development 20 , processing of plant materials before extraction of oils 16,20 and occurrence of chemotypes (varieties) 27,36 .…”

“…The essential oils obtained by hydrodistillation or steam distillation from these aromatic and medicinal herbs were shown to possess good antimicrobial activities against a wide range of microorganisms 7,[9][10][11][12] and also antioxidant activities 10,13 . The biological activity of the essential oils depends on their chemical compositions, which could be influenced by several factors such as agronomic conditions 14 , genotypes of plants 15 , drying methods 16 , extraction methods 17 , geographical locations 18 and harvest seasons 10 . However, the effects of different daytimes of harvest on their chemical composition could not be neglected.…”

Abstract:The chemical composition of essential oils obtained by hydrodistillation from aerial parts of Ocimum basilicum, Ocimum canum and Ocimum gratissimum from Benin as affected by harvesting time, were analyzed by GC-FID (Gas chromatography-Flame ionization detector) and GC-MS (Gas chromatographyMass spectrometry). Based on the composition analysis, major components were as follows: estragol (43.0 -44.7 %) and linalool (24.6 -29.8 %) in O. basilicum oils; carvacrol (12.0 -30.8 %) and p-cymene (19.5 -26.2 %) in O. canum oils; thymol (28.3-37.7 %) and γ-terpinene (12.5-19.3 %) in O. gratissimum oils. Disc diffusion and broth microdilution assays were used to evaluate the antibacterial activity of essential oils and their main components against two foodborne bacteria, Listeria monocytogenes and Salmonella enterica serotype Typhimurium. The tested oils and their components exhibited notable antimicrobial activities against L. monocytogenes and S. Typhimurium. The O. canum and O. gratissimum oils collected at 7h and 19h showed significant higher activities against L. monocytogenes and S. Typhimurium (MICs and MBCs 0.34 -2.5 μL/ mL) (p < 0.05), whereas O. basilicum showed lower activity (MICs and MBCs 2.0 -8.0 μL/mL) at any daytime of harvest, the weakest being at 19h (MIC and MBC 12.0 -32.0 μL/mL). The daytime of harvest can influence the composition of oils and their activities on bacteria.

There are distinct varieties of basil types in the genus Ocimum which makes them very special. Genus Ocimum is widespread over Asia, Africa and Central & Southern America. All basils are member of the Lamiaceae family. The colors of the leaves vary from bright green to purple-green and sometimes almost black. Fresh basil leaves have a strong and characteristic aroma, not comparable to any other spice, although there is a hint of clove traceable. Ocimum Sanctum, also addressed as Ocimum Tenuiflorum is a sacred plant in the Hindu culture and known as Tulasi in Tamil or Holy Basil in English. Meanwhile Ocimum Basilicum, known as Common or Sweet Basil has very dark green leaves. The genus Ocimum is cultivated for its remarkable essential oil which exhibits many usages such as in medicinal application, herbs, culinary, perfume for herbal toiletries, aromatherapy treatment and as flavoring agent. Due to varying essential oil profiles even within the same species, plants may often be classified as a different species as a result of different scents. In the present study, volatile constituents of Ocimum Sanctum and Ocimum Basilicum were extracted using various solvents and their chemical constituents were identified and quantified by using GC-MS in optimized conditions. The profiles of extract from both species were compared in an effort to investigate effects of seasonal variation on their chemical compositions. The predominant species in Ocimum Sanctum and Ocimum Basilicum was found to be methyl eugenol and methyl chavicol, respectively, during different months of analysis.

“…O. basilicum 'Rosso' is a cultivar for decorative purposes; it is purple basil with high anthocyanidin content. Compared to the essential oil content in O. basilicum cultivars from the experimental garden in Prague (Klimánková et al 2008), our O. basilicum 'Rosso' is most similar to the Czech cultivar V, while O. basilicum 'Eco Genovese' is more similar to the Czech cultivars I-IV.…”

-The effects of a biodynamic sowing calendar on the growth (plant height, fresh herb yield, nodes number) and quality (percentage of leaf mass, essential oil content) of three basil species, Ocimum americanum L., Ocimum × hybrida and Ocimum basilicum L., represented by the cultivars 'Rosso' and 'Eco Genovese', were tested. Statistical analyses showed that the species had greater impact on the observed parameters than either the sowing date or the species and sowing date in combination. The species showed a signifi cant infl uence on all fi ve tested parameters, while sowing date and interaction of both factors signifi cantly infl uenced plant height, leaf percentage and essential oil content. The best yield per plant was obtained for O. × hybrida and O. basilicum 'Eco Genovese'. The lowest species O. × hybrida produced the highest amount of essential oil. »Nodes number« parameter most clearly separated the species, but not the cultivars. Even though O. americanum gave the tallest plants, it did not yield either the highest amount of fresh herb or essential oil. This species' height was most consistent, considering the signifi cant impact of biodynamic rhythm. Sowing date was not crucial for basil fresh yield; however if there is a need for taller plants with a higher percentage of leaf mass and more essential oil, sowing date needs to be controlled.
