Comparative analysis and antimicrobial action of some essential oils from plants
2021
In this research, essential oils (EOs) were extracted through steaming from aerial parts of three plants: basil (Ocinum basilicum L.), peppermint (Mentha piperita L.) and oregano (Origanum vulgare L.) form Sibiu County, Romania. The GC-MS analysis indicated that eugenol and apiol were the major compounds in the basil EO. Timol, ɣ-terpinene, and p-cymene were the major compounds in the volatile oil extracted from oregano and menthol and methone the main components in the peppermint EO. In the first 48 h of analysis, basil EO inhibition action was the highest against Salmonella anatum (48%), followed by Aspergillus niger (26%), Bacillus cereus (21%) and Saccharomyces cerevisiae (15%); this ac…
Essential oil variability in a collection of Ocimum basilicum L. (basil) cultivars.
2016
Ocimum basilicum L. (Lamiaceae) is an aromatic plant of great tradition in the Mediterranean area. Its economic importance is growing up determining an expansion of cultivation. This paper evaluated the morphological traits, the chemical profiles, and antibacterial activity of 21 cultivars of basil belonging to Ê»Genoveseʼ, Ê»Napoletanoʼ, and Ê»Purple basilʼ types. The cultivars were characterized by different growth rate and morphological traits. The chemical composition of the oils analyzed by GC and GC/MS analysis, supported by the PCA analysis, underlined the strong influence of chemotype. It is noteworthy that estragole, never present in Genovese and purple basil types, occurred in …
Antibacterial activity of Ocimum basilicum L. essential oil against Gram-negative bacteria
2016
Wstęp. Bazylia pospolita (Ocimum basilicum L.) jest powszechnie stosowaną w medycynie ludowej rośliną zielną. Ziele bazylii zawiera do 2,5% olejku eterycznego, a składnikami dominującymi są: linalol, 1,8-cyneol, metylochawikol oraz eugenol. Prozdrowotne właściwości olejku bazyliowego związane są między innymi z jego działaniem: przeciwbakteryjnym, przeciwgrzybiczym, przeciwwirusowym oraz przeciwutleniającym. Cel pracy. Celem pracy było określenie aktywności przeciwbakteryjnej olejku bazyliowego wobec bakterii Gram-ujemnych. Materiał i metody. W pracy oceniono wpływ olejku bazyliowego oraz czas jego działania na przeżywalność Gram-ujemnych bakterii. Badanie wrażliwości bakterii na olejek baz…
Use of plant growth-promoting rhizobacteria (PGPR) and organic fertilization for soilless cultivation of basil
2021
Abstract Today there is a greater environmental and ecological awareness and it is growing the number of farmers who want to adopt sustainable and efficient cultivation systems even if not officially certified as organic. Sustainable and modern cultivation systems must involve organic fertilization and cannot ignore the role of rhizosphere microorganisms. Starting from this premise, this paper aimed to evaluate the use of plant growth-promoting rhizobacteria (PGPR) and organic liquid fertilizers on soilless cultivation of basil. Genovese basil plants were cultivated in pots filled with a substrate inoculated or not with a commercial biostimulant (TNC BactorrS13) containing growth-promoting …
Basil (Ocimum basilicum), a new host of Pepino mosaic virus.
2009
Pepino mosaic virus (PepMV), a member of the genus Potexvirus , was first described in 1980 on pepino ( Solanum muricatum ) and was later isolated from different wild species of the genus Solanum (formerly Lycopersicon ) (Soler et al ., 2002). PepMV has been reported in several European countries and in North America, causing disease in tomato. In July 2008, plants of basil ( Ocimum basilicum ) showing interveinal chlorosis on young leaves were observed in three greenhouses in Sicily, in the area where tomato plants were found to be infected by PepMV in 2005 (Davino et al ., 2006). The disease was transmitted mechanically to Nicotiana benthamiana , producing chlorotic spots and leaf deforma…
De novo production of six key grape aroma monoterpenes by a geraniol synthase-engineered S. cerevisiae wine strain
2015
[Background] Monoterpenes are important contributors to grape and wine aroma. Moreover, certain monoterpenes have been shown to display health benefits with antimicrobial, anti-inflammatory, anticancer or hypotensive properties amongst others. The aim of this study was to construct self-aromatizing wine yeasts to overproduce de novo these plant metabolites in wines.
Volatile flavour components of ocimum basilicum var. hispidum (lam.) Chiov.
1991
The volatile components obtained by steam-distillation ofOcimum basilicum var. hispidum (Lam.) Chiov. (Labiatae) were analysed by gas chromatography (GC) and gas chromatography—mass spectrometry (GC-MS). A total of 21 compounds, representing ca 90% of the total oil, were identified. The identity of the main component (82%), dihydrotagetone, was confirmed by 1H- and 13C-NMR spectroscopy. This is the first report of this compound in the genus Ocimum.
The Influence of Scalded Flour, Fermentation, and Plants Belonging to Lamiaceae Family on the Wheat Bread Quality and Acrylamide Content
2018
The aim of this study was to investigate the influence of additives such as plants belonging to Lamiaceaefamily (Thymus vulgaris, Carum carvi, Origanum vulgare, Ocimum basilicum, and Coriandrum sativum), scalded flour (SF) or scalded flour fermented with Lactobacillus plantarumLUHS135 (SFFLp) on the quality and acrylamide formation in wheat bread. The formation of acrylamide and bread quality significantly depended on the king of plants used and the amount of SF and SFFLp used. The additives of T. vulgarisand SF increased the content of acrylamide by 3.4-fold in comparison with bread prepared without SF, whereas the addition of SFFLp significantly reduced the content of acrylamide in bread,…
Essential Oil Composition of the Aerial Parts of FiveOcimumspecies from Western India
2015
AbstractChemical composition of the essential oils of five Ocimum species namely Ocimum tenuiflorum syn Ocimum sanctum L. (green and purple), Ocimum kilimandscharicum Guerke, Ocimum viride Willd, Ocimum basilicum L. and Ocimum gratissimum L., obtained by a hydrodistillation was determined by GC and GC-MS. A total of one hundred three compounds were identified in the oils of five Ocimum species, of which fifteen compounds were found to be major (5.0–81.8 %) compounds. Analysis of Ocimum viride oil showed the highest amount of eugenol (81.8 %) among species besides germacrene D (7.0 %) and cis-ocimene (4.1 %). Ocimum tenuiflorum green and Ocimum tenuiflorum purple were found contain eugenol (…
Kasvien kasvun ja laadun vertailu hydroponic- ja aquaponic-systeemeissä
2017
Yhdistetystä kalanviljelystä ja kasvien vesiviljelystä eli aquaponic-viljelystä lupaillaan helpotusta ruoantuotannon globaaleihin ongelmiin sillä se vähentää vesiviljelyyn tarvittavien ravinteiden määrää hyödyntäen kalojen jätösten ravinteet kasvisadon tuottamiseen. Aquaponic-viljelyllä on siis potentiaalia lisätä ruoantuotannon tehokkuutta, mutta sen laajamittaista käyttöönottoa hidastavat viljelyn monimutkaisuus sekä korkeat aloituskustannukset. Kaupallinen tehotuotanto on toistaiseksi ollut vaatimatonta, näin ollen aquaponicsin taloudellisesta tuottavuudesta on vähäisesti tutkimustuloksia. Tutkimuksemme tarkoitus oli tuottaa lisää tietoa kasvien kasvusta ja laadusta aquaponic-systeemissä…
