The effects of fruit bagging treatments with seven different types bags on the physicochemical characteristics three table grape cultivars: RuiduZaohong (RDZH), RuiduHongyu (RDHY), and RuiduHongmei (RDHM) were investigated. Headspace-solid-phase micro-extraction combined gas chromatography mass spectrometry (HS-SPME-GC-MS) was used to determine compositions monoterpenes in fruit. results showed...

The chemical composition of the Hydrolate of Citrus aurantium L. (Rutaceae) flowers (neroli) grown in Iran, and two commercial hydrolates were analyzed by GC/MS. Thirty compounds (90.3%) were identified in the Hydrolate by the use of laboratory apparatus, thirty-eight compounds (83.4%) in the Hydrolate from the traditional method and fifteen compounds (98.3%) in the industrially produced sample...

Terpinoller monoterpen bileşikler olup, birçok çalışmada antioksidan özelliklerinden dolayı antikanser, antikonvülsant ve antiülser gibi biyolojik etkileri ortaya konulmuştur. Araştırmanın amacını, LPS’in karaciğer hücrelerine uygulanarak oluşturulan yangı modelinde, α-terpineol’ün antiinflamatuar antiapoptotik biyofonksiyonlarının araştırılması oluşturmuştur. Denemede insan orijinli HepG2 (ATC...

A method for the analysis of several volatiles compounds responsible for orange juice flavour (ethyl butanoate, limonene, linalool, alpha-pinene, geranial, neral and alpha-terpineol) has been developed. The isolation of this compounds was carried out by pervaporation (PV) followed by on-line gas chromatography-mass spectrometry (GC-MS). The coupling PV-GC-MS has been successfully applied to fre...

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...

The aim of the study was to examine the antibiofilm activity of selected essential oils (EO): Lavandula angustifblia (LEO), Melaleuca alternifolia (TTO), Melissa officinalis (MEO) and some of their major constituents: linalool, linalyl acetate, alpha-terpineol, terpinen-4-ol. Biofilms were formed by Staphylococcus aureus ATCC 29213 and Escherichia coli NCTC 8196 on the surface of medical biomat...

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...
