The aim of the study was to determine the antifungal effects of the essential oils against fungal pathogen Botrytis cinerea the causal agent of grey mould disease of peach (Prunus persica L.) under in vitro and in vivo conditions. Treatments consisted of four essential oils (anise, ammi, ziziphora and cinnamon) and five concentrations (0, 200, 400, 600 and 800 μL.L).Results of in vitro experime...

the essential oils obtained by hydrodistillation (hd), steam distillation (sd) and solvent free microwave extraction (sfme) from the stems and flowers of tanacetum tenuisectum (boiss.) podl., which is endemic to iran,were analyzed by gc and gc/ms.camphor (26.9 %, 27.2% and 25.5%), borneol (12.6%, 11.5% and 7.6%) and 1, 8-cineole (7.9%, 13.2% and 11.3%) were the main constituents of the hd, sd a...

Background & Aim: Salvia hydrangea is one of the medicinal plants belonging to Lamiaceae family. Medicinal plants can be marketed as fresh or dried products; however aromatic plants are often dried before extraction to reduce moisture content. The aim of this study was to evaluate the impact of different drying methods on qualitative and quantitative changes in essenti...

Essential oil extracts from their leaves were tested for efficacy on the morality of the maize grain weevil, Sitophilus zeamais (Coleoptera, Curculionidae). Concentrations of the essential oils relative to the maize grains of 0.013, 0.025, 0.05 and 0.1% (v/w) were used for A. conyzoides and 0.063,...

The volatile organic compounds (VOCs) of two Coronilla species (Coronilla orientalis Miller and Coronilla varia L.) obtained by hydrodistillation (HD) and solid phase microextraction (SPME) techniques were identified by GC-FID/MS. The major compounds identified in the SPME extracts were limonene (43.4%) in C. orientalis, (Z)-β-ocimene and (E...
