Przemysłowe zastosowanie pelargoniowego olejku eterycznego

2018

Od wielu lat ekstrakty roślinne, w tym olejki eteryczne wykorzystywane były nie tylko ze względu na ich walory zapachowe, ale także lecznicze. Mogą być one pozyskiwane z różnych części roślin, co wpływa na skład jakościowy pozyskanego olejku i wydajność wyjściowego materiału. Badania zawarte w tej pracy skupiają się na roślinach z rodzaju Pelargonium, obejmujący około 250 gatunków, a który jest bardzo ceniony ze względu na zawartość olejku eterycznego, wykorzystywanego w wielu gałęziach przemysłu, m.in. perfumerii, przemyśle kosmetycznym (m.in. mydła czy kremy) spożywczym czy farmaceutycznym. Pierwszym celem pracy było przedstawienie mnogości zastosowań pelargoniowego olejku, a także jego d…

Działanie pelargoniowego olejku eterycznego na Bacillus spp.

2018

Pelargonia pachnąca (Pelargonium graveolens) jest aromatycznym krzewem posiadającym jasnozielone, owłosione, miękkie w dotyku, karbowane liście i małe, różowe kwiaty. Należy do rodzaju Pelargonium (Geraniaceae) i liczy ponad 250 gatunków. Olejek eteryczny pozyskiwany z pelargonii jest bardzo ceniony nie tylko przez przemysł perfumeryjny czy aromaterapię, ale także przez przemysł spożywczy, kosmetyczny jak i farmację. Roczną produkcję olejku szacuje się na 300 ton. Liczne badania wskazują na jego silne właściwości przeciwbakteryjne, przeciwwirusowe, przeciwbólowe czy przeciwzapalne. Celem przeprowadzonych badań było określenie aktywności olejku pelargoniowego wobec Bacillus spp. Zebrano jedn…

Characterization of the metabolic profile and identification of potential therapeutic targets in advanced prostate cancer patients

2023

INTRODUCCIÓN El cáncer de próstata (CaP) representa el segundo tumor en incidencia en hombres y es la quinta causa de muerte por cáncer a nivel global. El CaP es un tumor hormono-dependiente, que requiere de la activación del receptor de andrógenos (AR) para su proliferación. Clínicamente, se caracteriza por una gran variabilidad en su evolución, progresando desde una condición indolente hasta un fenotipo agresivo que puede diseminarse y metastatizar a los nodos linfáticos y huesos. Actualmente, el diagnóstico temprano del CaP se realiza mediante la determinación sérica del antígeno prostático específico (PSA) y el examen rectal digital (DRE). Si estas pruebas dan resultados anómalos y hay …

SHORT-TERM RESPONSE OF SOIL MICROORGANISMS TO ESSENTIAL OILS WITH ALLELOPATHIC POTENTIAL EXTRACTED FROM MEDITERRANEAN PLANTS

2015

Essential oils (EOs) with allelopathic compounds have been used to reduce or avoid weed germination and growth. The aim of this study was to evaluate the potential phytotoxic effects of EOs extracted from different Mediterranean plants on soil microbial biomass and activity. EOs were extracted from leaves of Eucalyptus camaldulensis Dehnh (EUC); Eriocephalus africanus L. (ERI); Thymus capitatus (L.) Hoffmanns. & Link (TCP); Citrus reticulata Blanco var. ‘Clemenules’ (TAN) and Citrus limon (L.) Osbeck var. ‘Eureka’ (LEM). Each EO was supplied to pots containing 560 g of soil at three different doses (low, medium, high). After 15, 30, 90, 120 days the supply of EOs, soils were destructively a…

Virtualization of work in global supply chains

2016

ABSTRACT. Background: The paper is devoted to the notion and benefits of implementing virtual work in global supply chains. Virtual work must be understood as an intentional activity of a human being, aimed at rendering services (tangible and intangible), by means of ITC tools, performed in a distance from the traditional place of work, in a mobile manner. The empirical research were conducted on the basis of 4 case studies of global leaders of supply chains, which in accordance with M. Fisher's classification, represent two types. The case studies confirmed the positive influence of virtual work both in effective and flexible supply chains. Favourable market and technological conditions an…

INTRODUCTION Global economic crisis significantly increases the pressure on reduction of cost and risk connected with the functioning of global supply chains. Among many ways to reduce the cost and the uncertainty of demand for the products of supply chain the essential one is the increase of information transparency due to modern ICT solutions.

Herbicidal activity of essential oils extracted from different Eucalyptus and Citrus species against Avena fatua

2018

Weeds are a serious threat for crop yield and quality since they compete for water, light, soil nutrients and space. Avena fatua L. is one of the ten worst annual weeds of temperate agricultural regions of the world. It could reduce annual crop yields by as much as 70%. The main traits of this species include high fecundity, self-pollination, and variable degrees of primary seed dormancy. A. fatua is in the 4th position of herbicide resistant weeds in the word. It has developed resistance to eight different modes of action. .. The European legislation also supports weed control by means of Integrated Pest Management. It is important to manage A. fatua interference preventing environmental p…

Study of quantitative and qualitative variations in essential oils of Sicilian oregano biotypes

2015

Essential oil (EO) was extracted using hydrodistillation from samples of Origanum vulgare subspecies hirtum (Link) Ietswaart, gathered from the wild in various parts of Sicily, Italy; GC-FID and GC-MS analyses were subsequently performed. The aim of the study was to analyze the relationship between essential oil yields and the geographical distribution of oregano wild populations based on variations in environmental factors as collection sites. Moreover, the purpose was to group Origanum vulgare subspecies hirtum biotypes according to the chemical composition of the EO. The seven principal components in the EO was thymol (24.0–54.4%), γ-terpinene (9.8–30.5%), ρ-cymene (5.2–18.7%), α-terpine…
