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…
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…
The use of leaves of Rosmarinus officinalis L. as samplers for polycyclic aromatic hydrocarbons. Assessment of air quality in the area of Palermo
2002
The quantitative analysis of polycyclic aromatic hydrocarbons (PAHs) in vegetables and animals allows us to evaluate the quality of air, in a determined geographic area, without the need of making long samplers with complicate instrumentation. In this work, Rosmarinus officinalis leaves have been used as passive samplers. In particular, this plant was chosen because it is widespread in the Mediterranean area and it is commonly found both in the metropolitan and in the peripheral areas of the city of Palermo. Results for the concentration of total polycyclic aromatic hydrocarbons (the sum of the 22 compounds) and the PAHs distribution in leaves from Rosmarinus officinalis are presented. Puri…
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…
Agronomical and postharvest evaluation of the essential oils of Sicilian rosemary (Rosmarinus officinalis L.) biotypes
2019
Rosmarinus officinalis L. is an aromatic shrub commonly found in the Mediterranean area. It is used in cooking both to add aroma and as a preservative in processed foods. Essential oils of rosemary are used in medicine and in the cosmetics industry due to their considerable biological properties. The yield and quality of rosemary essential oils mainly depend upon the chemo type, environmental conditions and cultivation techniques. The aim of this study was to evaluate the qualitative and quantitative characteristics of essential oils of wild R. officinalis biotypes found in Sicily using different drying methods. Five types of drying methods were used for the tests: a) shade drying under a r…
