The objective of this study was to evaluate the antimicrobial potential essential oil (EO) from L. origanoides against Gram-negative bacteria with multidrug resistance (MDR) phenotype and correlate results obtained genetic profile these microorganisms. extracted leaves plant by steam dragging condensation Clevenger equipment, chemical components were identified quantified gas chromatography cou...

The present work reports the phytoconstituents in essential oil and four different solvent extracts of Cinnamomum tamala leaves. Their antibacterial, antifungal, antioxidant potential were also evaluated. extraction was performed by hydro-distillation using Clevenger apparatus its chemical composition identified gas chromatography coupled with mass spectrometry (GC-MS). leaf obtained cold perco...

Background & Aim: A simple and rapid microwave- assisted extraction (MAE) procedure was developed and optimized for the isolation of borneol and bornyl acetate from Ferulago macrocarpa. Ferulago macrocarpa (Apiaceae) is an endemic plant in Iran. Experimental: Dried powdered aerial parts of plants were soaked in water and irradiated with microwave in a Clevenger extraction app...

The chemical composition of the essential oil obtained from aerial parts of Galium verum L. (Rubiaceae) from Iran was examined by a combination of GC and GC/MS. The oil isolated by hydro-distillation using a Clevenger-type apparatus. Air-dried aerial parts of Galium verum (80 g) which were collected from Bomehen in Tehran province at full flowering stage on May 2003, were subjected to hydro-dis...

This study was conducted to determine the insecticidal activity of essential oils from oregano, Origanum onites L. (Lamiales: Lamiaceae), savory, Satureja thymbra L. (Lamiales: Lamiaceae), and myrtle, Myrtus communis L. (Rosales: Myrtaceae) against three stored-product insects. Essential oils from three species of plants were obtained by Clevenger-type water distillation. The major compounds in...

Graham, J.L., J.R. Jones, S.B. Jones and T.E. Clevenger. 2006. Spatial and temporal dynamics of microcystin in a Missouri reservoir. Lake and Reserv. Manage. 22(1):59-68. Environmental factors associated with spatiotemporal variation of microcystin (MC) in Mozingo Lake, a Missouri reservoir, were studied during summer 2001, and annual MC trends were characterized from May 2001-May 2002. MC incr...

Laurus nobilis L. (sweet laurel) is one of the volatile oil bearing plants of Lauraceae family. It is cultivated in different parts of Iran and its leaves and fruits have been used in food, cosmetics and pharmaceutical industries. There are a few reports about the effects of some environmental conditions on the quality and quantity of laurel volatiles. The goal of our work was to search the sea...

Microwave-assisted extraction of volatile oils (MAE) potentially offers a more efficient and bio-sustainable method than conventional extraction by Clevenger apparatus (CE). This study aimed to optimise the MAE of the volatile oil from Pterodon emarginatus fruits and characterise the volatile compounds. A 2³ full-factorial central composite design and response surface methodology were used to e...

The Ruta graveolens L. (Rutaceae) plant is used medicinally as a homeopathic remedy in various areas of the world. In this study, volatile oils were extracted from the areal parts of the plant which was collected from southern India, then investigated for its chemical constituents and antimicrobial activities. The volatile oils were extracted by hydrodistillation using a Clevenger apparatus and...
