Exploring the chemical diversity of essential oils in Armenian markets: a comprehensive analysis of composition profiles
2023
Due to its location at the convergence of multiple biogeographical regions, Armenia experiences significant variations in climate and soil conditions, resulting in a diverse range of plant chemotypes. However, there has been a lack of recent reports on the biological activity of plants found in Armenia's flora. There are few with well-described essential oil profiles, despite the vast biodiversity of Armenian flora. This study aimed to analyse the chemical composition of essential oils used by the population and found in the Armenian market. Unfortunately, only essential oils of foreign origin can be found, like Russia. Three essential oils of Lavandula angustifolia, Abies sibirica, and Ros…
HPTLC and GC-MS for separation and identification of eugenol in plants
2007
Samples of clove, nutmeg, and cinnamon have been extracted by maceration with ethanol for 24 h and with aqueous ethanol 48 h. Rhizomes of herb bennet ( Geum urbanum ) and calamus ( Aconum calamus ) and roots of valerian ( Valeriana officinalis ) have been subjected to aqueous hydrolysis then extraction with dichloromethane. The active principles from the samples were separated on silica gel HPTLC plates, with pure (standard) and dental (pharmaceutical) eugenol, using n -heptane-ethyl acetate 60+40 ( v / v ) as mobile phase. After development the components were visualized in UV light at λ = 254 nm. The presence of eugenol was confirmed by GC-MS.
Teratogenicity and Developmental Toxicity of Herbal Products
2017
Developmental toxicology and research in teratogenicity focus on xenobiotic substances that damage embryos and fetuses and lead to death, growth retardation, and/or malformation of offspring. While considerable information has been acquired about synthetic drugs and environmental xenobiotics, much less is known about the teratogenicity of herbal products. In this chapter we report on some major topics of developmental toxicity and teratogenicity, and discuss the safety of a few selected medicinal herbs in this context, i.e., Artemisia annua L., Caulophyllum thalictroides (L.) Michx., Echinacea spec,. Glycyrrhiza spec., herbs derived from Chinese medicine, Hypericum perforatum L., Panax gins…
Cytotoxicity of the bisphenolic honokiol from Magnolia officinalis against multiple drug-resistant tumor cells as determined by pharmacogenomics and …
2014
A main problem in oncology is the development of drug-resistance. Some plant-derived lignans are established in cancer therapy, e.g. the semisynthetic epipodophyllotoxins etoposide and teniposide. Their activity is, unfortunately, hampered by the ATP-binding cassette (ABC) efflux transporter, P-glycoprotein. Here, we investigated the bisphenolic honokiol derived from Magnolia officinalis. P-glycoprotein-overexpressing CEM/ADR5000 cells were not cross-resistant to honokiol, but MDA-MB-231 BRCP cells transfected with another ABC-transporter, BCRP, revealed 3-fold resistance. Further drug resistance mechanisms analyzed study was the tumor suppressor TP53 and the epidermal growth factor recepto…

Phytosociological analysis of the Genista sp. pl. garrigues of the Cisto-Lavanduletea and Rosmarinetea officinalis classes in the South-Tyrrhenian ar…
2015
The study reviews the Genista sp. pl. garrigues ascribable to the classes Cisto-Lavanduletea (acidophilous communities on volcanics and quartzarenites) and Rosmarinetea officinalis (basiphilous communities on calcareous and calcareous-dolomite substrates), in the southern territories of the Italo-Tyrrhenian Province. The floristic-synecological characterization of the identified coenoses led to the description and/or redefinition of various new syntaxa. They are distributed in the two new suballiances Calicotomo villosae–Genistenion tyrrhenae and Genisto aristatae–Calicotomenion infestae of the class Cisto- Lavanduletea (Lavanduletalia stoechadis and Calicotomo villosae–Genistion tyrrhenae)…
Biowaste in a circular bioeconomy in Mediterranean area: A case study of compost and vermicompost as growing substrates alternative to peat
2020
European policies are advocating a transition toward circular bio-economy, an economy aiming at reducing the dependence from fossil-based resources, limiting greenhouse gas emissions and environmental impacts. The aim of this paper is to assess the potential for circularity for bio-waste and related by-products, to highlight the role of compost and vermicompost in the circular bioeconomy and their use in the agricultural sector. Three different substrates were tested in the soilless cultivation of Salvia officinalis, a Mediterranean nutraceutical and healthy plant: vermicompost (40%), compost (40%) and peat (100%). The average values of the main biometric parameters were calculated and comp…
Wild Sicilian Rosemary: Phytochemical and Morphological Screening and Antioxidant Activity Evaluation of Extracts and Essential Oils
2015
To identify the best biotypes, an extensive survey of Sicilian wild rosemary was carried out by collecting 57 samples from various sites, followed by taxonomic characterization from an agronomic perspective. All the biotypes collected were classified as Rosmarinus officinalis L. A cluster analysis based on the morphological characteristics of the plants allowed the division of the biotypes into seven main groups, although the characteristics examined were found to be highly similar and not area-dependent. Moreover, all samples were analyzed for their phytochemical content, applying an extraction protocol to obtain the nonvolatile components and hydrodistillation to collect the essential oil…
Chemical composition of essential oils from Pantelleria Island autochthonous and naturalized spices and evaluation of their individual and combined a…
2019
In this study, the antimicrobial activity of the essential oils (EOs) from Origanum majorana L. and Rosmarinus officinalis L. growing in Pantelleria (Sicily, Italy) were tested alone and in combination against some prokaryotic and eukaryotic food-borne pathogens. The chemical composition of the EOs as well as the minimum inhibitory concentrations (MIC) against the most sensitive strains were also determined. Both EOs showed interesting antimicrobial effects against all bacteria and yeasts tested. MIC was in the range 1.25–2.50 µl/ml. Interestingly, O. majorana was particularly rich in thymol acetate, while carvacrol was present at very low percentages. Also R. officinalis EOs composition wa…
Effects of Vermicompost, Compost and Digestate as Commercial Alternative Peat-Based Substrates on Qualitative Parameters of Salvia officinalis
2021
Peat is a common substrate used for the cultivation of potted plants. However, the use of peat in horticulture has recently been questioned from an environmental standpoint, since it is a non-renewable resource and plays a major role in atmospheric CO2 sequestration. The aim of this work was to assess the potentialities of substrates obtained from vermicompost, compost and anaerobic digestion processes to partially substitute peat for sage (Salvia officinalis L.) cultivation. Therefore, we planned an experiment to assess the effect of these substrates on essential oil (EO) yield and composition, as well as on leaf nutrients concentration of sage plants. The three substrates were mixed with …
