The ethnobotany, phytochemistry and biological properties of genus Ferulago – A review
2020
Abstract Ethnopharmacological relevance The genus Ferulago, belonging to the Apiaceae family, is found mainly in the Mediterranean area, Southwest and Middle Asia, the Caucasus and North Africa. Since ancient times, species of this genus have been largely employed in traditional medicine for their biological properties such as antimicrobial, anti-inflammatory, antispasmodic, insecticidal, and anti-malaria, cholinesterase inhibition effects, etc. Aims The scope of this paper is to present a comprehensive respect review of this interesting genus including traditional uses, chemical composition of volatile and non-volatile metabolites, and in vitro and in vivo biological properties either util…
PHYTOTOXIC POTENTIAL OF EUCALYPTUS ESSENTIAL OILS FOR WEED CONTROL
2018
The widespread use of synthetic herbicides has resulted in herbicide-resistant weeds, disturbed ecological balance and negative effects on human health. Due to this fact, it is necessary to rely on alternative weed control strategies using natural compounds released by plants, such as essential oils (EOs). EOs have a short half-life since they are biodegradable, and are safer than synthetic compounds, with little damage to the environment, without even contaminating ground water (Topal and Kocaçalıskan 2006). Essential oils from different species contain allelochemical compounds that possess significant phytotoxic activity. Azizi and Fuji (2006) demonstrated that Eucalyptus (family Myrtacea…
Faceted phospholipid vesicles tailored for the delivery of Santolina insularis essential oil to the skin
2015
The aim of this work was to formulate Santolina insularis essential oil-loaded nanocarriers, namely Penetration Enhancer containing Vesicles (PEVs), evaluate the physico-chemical features and stability, and gain insights into their ability to deliver the oil to the skin.S. insularis essential oil was obtained by steam distillation, and was predominantly composed of terpenes, the most abundant being β-phellandrene (22.6%), myrcene (11.4%) and curcumenes (12.1%). Vesicles were prepared using phosphatidylcholine, and ethylene or propylene glycol were added to the water phase (10% (v/v)) to improve vesicle performances as delivery systems. Vesicles were deeply characterized by light scattering,…

Chemical composition of the essential oil of Salvia multicaulis Vahl. var. simplicifolia Boiss. growing wild in Lebanon
2004
The essential oil of aerial parts of Salvia multicaulis Vahl. var. simplicifolia Boiss. (Lamiaceae) growing wild in Lebanon was obtained by hydrodistillation and was analysed by GC and GC-MS. 67 compounds constituting 95.2% of the oil were identified, the major components being alpha-copaene (8.0%), alpha-pinene (6.6%), myrtenol (5.7%), trans-sabinyl acetate (5.3%).
GC and GC-–MS Analysis of Volatile Compounds From Ballota nigra subsp. uncinata Collected in Aeolian Islands, Sicily (Southern Italy)
2020
In the present study, the chemical composition of the essential oils from aerial parts of Ballota nigra subsp. uncinata (Bég.) Patzak collected in Sicily was evaluated by gas chromatography (GC) and GC-mass spectrometry. The main components of the oil were ( E)-phytol (20.0%), α-pinene (9.0%), hexahydrofarnesyl acetone (5.7%), and α-selinene (5.1%). Cluster analysis of the essential oil compositions of all the taxa belonging to B. nigra s.l. group was performed.
Study of quantitative and qualitative variations in essential oils of Sicilian Rosmarinus officials L.
2015
In this study the chemical characterizations of 10 sicilian biotypes of Rosmarinus officinalis L. essential oils are reported. The main goal was to analyze the relationship between the essential oils yield and the geographical distribution of the species plants. The essential oils were analyzed by GC-FID and GC-MS. The statistical methods Hierarchical Cluster Analysis and Principal Component Analysis were used to cluster biotypes according to the chemical composition of the essential oils. The essential oil yield ranged from 0.8 - 2.3 (v/w). 82 compounds have been identified, these represent 96.7-99.9% of the essential oil. The compounds mostly represented in the essential oils were: 1.8- C…
Contribution to a Taxonomic Revision of the Sicilian Helichrysum Taxa by PCA Analysis of Their Essential-Oil Compositions
2016
The chemical profile of the essential oils in ten populations of the genus Helichrysum Mill. (Asteraceae), collected in the loci classici of the nomenclatural types of the taxa endemic to Sicily, were analyzed. Our results confirm that the analysis of secondary metabolites can be used to fingerprint wild populations of Helichrysum, the chemical profiles being coherent with the systematic arrangement of the investigated populations in three main clusters, referring to the aggregates of H. stoechas, H. rupestre, and H. italicum, all belonging to the section Stoechadina. The correct nomenclatural designation of the investigated populations is discussed and the following two new combinations ar…
Chemical Composition of the Essential Oil of Mentha pulegium Growing Wild in Sicily and its Activity on Microorganisms Affecting Historical Art Crafts
2017
The chemical composition of the essential oil from aerial parts of Mentha pulegium L. (Linné) collected in Sicily was evaluated by GC and GC-MS. The main components were pulegone (50.6%), piperitenone (27.8%) and menthone (6.9%). Comparison of this oil with other studied oils of different populations is discussed. The oil showed good antibacterial and antifungal activities against some microorganisms that infest historical art works.
Essential oils of Chiliadenus lopadusanus (Asteraceae).
2013
The essential oils from the leaves and flowers of Chiliadenus lopadusanus growing on Lampedusa Island were obtained by hydrodistillation and analyzed by GC-MS. The major component was camphor (39.4% in the leaves and 24.0% in the flowers), followed in the leaves by torreyol (6.7%), t-cadinol (5.2%) and 1,8-cineole (3.8%), while in the flowers by t-cadinol (15.2%), t-muurolol (5.1%) and torreyol (4.5%). Among the compounds identified, several seem to play a role in antibacterial, antifungal, allelopathic and spasmolytic activity. In addition, several compounds identified in this study seem to influence the attraction of Megachile (Eutricharaea) apicalis (Megachilidae) and Halictus (Seladonia…
