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 (…
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,…
Investigation of the hygienic safety of aromatic plants cultivated in soil contaminated with Listeria monocytogenes
2012
Abstract The present work was undertaken to investigate the survival of Listeria monocytogenes ATCC 19114T in soil during the whole crop cycle of rocket (Eruca sativa Mill.) and basil (Ocimum basilicum L.), to monitor its transfer to the leaves, and to evaluate its viability at harvest. To this purpose, the soil was N–P–K fertilized and four trials, obtained with different combinations of soil treatment, listerial inoculums and seed planting, were followed for each aromatic plant. Soil was weekly investigated for total microbial counts and L. monocytogenes evolution. At the starting time, un-inoculated autoclaved soil showed a limited microbial load (103 CFU g dw−1), while un-inoculated non…
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.
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…
Antioxidant activity of essential oils obtained from aerial part of some Lamiaceae species
2018
Introduction: Essential oils are the perspective source of natural antioxidants because some synthetic antioxidants are now suspected to be potentially harmful to human health. As free radicals can cause inflammatory diseases, cancer, atherosclerosis, and aging, antioxidants can inhibit oxidative chain reactions. Essential oils have a wide range of pharmacological effects as they are multicomponent mixtures of chemical compounds, mainly terpenoids and aromatic components. Materials and Methods: The antioxidant activity of essential oils obtained from aerial parts of Ocimum americanum, Lophanthus anisatus, Monarda fistulosa, and Satureja hortensis (Lamiaceae) has been evaluated spectrophotom…
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…
Development of high-performance thin layer chromatography method for identification of phenolic compounds and quantification of rosmarinic acid conte…
2020
ABSTRACT Aim: Representatives of Nepetoideae Burnett subfamily are promising species of the Lamiaceae Martinov family because of accumulating such valuable groups of secondary metabolites as terpenoids and polyphenols. A high-performance thin layer chromatography (HPTLC) fingerprint method for the qualitative determination of phenolic compounds and for the quantification of rosmarinic acid (RA) content in methanol extracts of five species of this subfamily was developed for the first time. Materials and Methods: Dried aerial parts of Dracocephalum moldavica L., Ocimum americanum L., Lophanthus anisatus (Nutt.) Benth., Monarda fistulosa L., and Satureja hortensis L. collected in flowering pe…
