The yield of hydrodistillation of a botanically certified Oleogum Resin of Boswellia sacra essential oil (5.5%); and its chemical constituents were determined. The GC/MS technique was used for the analysis of the oil. Several oil components were identified based upon comparison of their mass spectral data with those of reference compounds published in literature or stored in a computer library....

The volatile constituents of the essential oils of the peel, flower (neroli) and leaves (petitgrain) of bitter orange (Citrus aurantium L.) growing in Greece were studied by GC-MS. The analytical procedures enabled the quantitative determination of 31 components. More specifically, the components of the essential oils identified were: twelve in the peel, twenty-six in the flowers, and twenty an...

the hydro-distilled volatile oils, obtained from dried e ndocarp and hulls of persian bay laurel ( laurus nobilis var. angustifolia ) from laueaceae family were analyzed by gc/ms. thirteen and twelve compounds consisting 81.6% and 89.1% of the total components were identified of the oils obtained with a yield of 3% and 1.2% (w/w) respectively. differences of some compounds between endocarp and ...

Objective: This study is designed to extract and examine chemical composition, antimicrobial and antioxidant activity of the hydro-distillated essential oil of Murraya koenigii leaves from the south region of Tamilnadu, India. Matherials and Methods: Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS) analysis of the essential oil result was indicates the 33 different compo...

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...

This study evaluated the antimicrobial, antioxidant and toxicity activity of essential oils (EOs) Hymenaea courbaril L. var. bark Syzygium cumini (L.) Skeels leaves. The EOs were extracted by hydrodistillation chemically characterized gas chromatography coupled to mass spectrometry (GC/MS). ABTS DPPH assay used evaluate activity. For assay, lethality was against Artemia salina Leach. antimicrob...

In Europe, willow (Salix spp.) trees have been used commercially since the 1980s at a large scale to produce renewable energy. While reducing fossil fuel needs, growing short rotation coppices (SRCs), such as poplar or willow, may high impact on local air quality these species are known amounts of isoprene, which can lead production tropospheric ozone (O3). Here, we present long-term leaf-scale...
