The present study describes a procedure to isolate essential oils from Rosmarinus officinalis L. using simultaneous distillation–extraction (SDE). can be used for medicinal purposes, as well in the cooking and cosmetics industries. SDE technique extraction combines steam distillation combined with continuous solvent or co-solvent mixture, providing faster extractions low volumes. effect of natu...

Endemic yarrow (Achillea eriophora DC.) has been widely used in folk medicine for centuries. The impact of climatic and edaphic conditions was investigated on essential oil (EO) yield and compositions of different yarrow ecotypes, native to Kerman province in southeast of Iran. The aerial part of plants was collected from 13 naturalhabitats. Gas chromatography-mass spectrometry (GC-MS) analysis...

BACKGROUND Vietnam is a country blessed with many medicinal plants widely used as food and for medicinal purposes, and they contain a host of active substances that contribute to health. However, the analysis of chemical constituents of these plant species has not been subject of literature discussion. RESULTS In this study, the chemical compositions of essential oils of four Hedychium specie...

Objectives. The present work investigates the effect of essential oil from the twigs of Abies koreana on electroencephalographic (EEG) activity of human brain in order to understand the influence of binasal and uninasal inhalations. Methods. To accomplish this study, the essential oil from the twigs of A. koreana (AEO) was isolated by steam distillation and the EEG readings were recorded using ...

The hemlock woolly adelgid (HWA), Adelges tsugae Annand, has been recognized as a major pest of eastern hemlock, Tsuga canadensis Carriere, and the less frequently encountered Carolina hemlock, T. caroliniana Engelm. Biological control is seen as the most promising method of largescale control of HWA, however, there is currently no effective method for estimating population levels of biological...

The current study describes the composition of Salvia lavandulifolia (Vahl) essential oils (SlEOs) obtained from plants cultivated in Murcia (Spain), as determined by gas chromatography. Relative and absolute concentrations, the enantiomeric ratios of chiral compounds and the in vitro antioxidant, antienzymatic and antimicrobial activities are described. The main components of the SlEOs were ca...
