The present study was designed to determine the effects of the essential oil of Laurusnobilis L. (Lauraceae) and its three main components on α-glucosidase and reactive oxygenspecies scavenging activity. The chemical composition of the essential oil from Laurus nobilisL. leaves was analyzed by GC/GC-MS and resulted in the identification of 29 compounds,representing 99.18% of the total oil. 1,8-...

In this paper, comparison of the volatile components composition in the samples obtained by hydrodistillation and solid-phase microextraction of Salvia officinalis was described. Different sample preparation techniques showed considerable differences in volatiles composition, especially with respect to sesqui- and diterpenoids. The comparison of the sage essential oil obtained by hydrodistillat...

BACKGROUND Artemisia aerial parts are well known for antimicrobial activities including anti malaria. OBJECTIVES This study was carried out to evaluate the antimicrobial activity and chemical composition of essential oil from the seeds of Artemisia aucheri Boiss (Asteraceae). MATERIALS AND METHODS Essential oil was extracted from the powdered seeds of Artemisia aucheri by hydrodistillation....

PURPOSE Marrubium crassidens, a plant belonging to the family Lamiaceae, was studied for its volatile components present in the aerial parts of the plant during the flowering stage. METHODS The essential oil of the plant obtained through hydrodistillation of the dried plant material was assessed for its chemical composition by GC/MS and GC-FID analyses. RESULTS Twenty-five compounds were id...

The essential oil obtained from leaves of Melissa officinalis L. (Family of Lamiaceae) growing in Algeria, was investigated for its chemical composition and in vitro antimicrobial activity. The chemical composition was determined by hydrodistillation and analyzed by GC/MS and GC-FID. Sixty-three compounds were identified in the essential oil, representing 94.10 % of the total oil and the yields...

BACKGROUND AND OBJECTIVES The aim of this study was to evaluate the chemical composition and antimicrobial activity of Satureja hortensis and Trachyspermum copticum essential oils against different kinds of microorganisms in vitro. MATERIAL AND METHODS The antimicrobial activity was evaluated by micro broth dilution assay and the chemical composition of essential oils was analyzed by GC and G...

The essential oil from the flowering aerial parts of Heracleum lanatum Michx. family Apiaceae was obtained by hydrodistillation and analysed by combination of GC (RI) and GC-MS. The chemical composition of the isolated oil is reported for the first time. Sixty five compounds were identified representing 96.95% of the total oil. The chemical composition of the isolated oil was characterised by a...
