The essential oils obtained by hydrodistillation (Clevenger apparatus) from aerial parts of Astragalus gombiformis were analysed by gas chromatography coupled with mass spectrometry (GC/MS). This study showed that the A. gombiformis essential oils are complex mixtures of important natural compounds, which varied qualitatively and quantitatively between cultivated and wild plants and between phe...

The essential oil content in the inflorescence of lavender (Lavandula angustifolia Mill.) cultivated in the mid hills of Uttarakhand was found to be 2.8 % based o n the fresh weight. The oil was an alysed by capillary GC and GC– MS. Thirty seven constituents, representing 97.81 % of the o il were identified. The major components of the oil were linalyl acetate (47.56 %), linalool (28.06 %), lav...

Background and Aims Terpenes are major varietal aroma compounds significantly contributing to wine quality style. Autochthonous microbial starters can promote the formation release of terpenes thus highlight terroir typicality wines. This study compared physicochemical parameters, changes in terpene concentration, β-D-glucosidase activity sensory attributes Chardonnay wines fermented individual...

Abstract Purpose The application of bio-control plants in the agricultural processes is one effective ways to solve traditional synthetic pesticide residues. This study will investigate effect plant Litsea cubeba branch inter-row cover on soil bacterial community, soil-enriched metabolites, and mineral nutrition tea plantation, which provide a basis for use agroecological farming systems. Metho...

PURPOSE To determine the active ingredient in tea tree oil (TTO) responsible for its reported killing effect on Demodex mites, the most common ectoparasite found in the human skin extending to the eye. METHODS Using a reported in vitro killing assay to measure the survival time of adult Demodex folliculorum up to 150 minutes, we have screened serial concentrations of 13 of the 15 known ingred...
