Over the last few decades, efforts to transition global production of fuels and chemicals toward renewable carbon feedstocks have accelerated. A large portion these focused on valorization one most abundant sources, lignocellulose. Pretreatment lignocellulose is first critical step in this process. In study, novel ionic liquid (IL) systems consisting multiple ions known be effective at biomass ...

Essential oils from Amazonian species are gaining increasing interest worldwide due to their medicinal and cosmetic applications; however, the relation among chemical constituents biological properties not well explored. Therefore, present research aims obtain an understanding of bioactivity compounds in essential plants Annonaceae family (Bocageopsis pleiosperma, Onychopetalum amazonicum, Unon...

Many essential oils (EOs) of different plant species possess interesting antimicrobial effects on buccal bacteria and antioxidant properties. Eugenia klotzschiana Berg (pêra-do-cerrado, in Portuguese) is a species of Myrtaceae with restricted distribution in the Cerrado. The essential oils were extracted through the hydrodistillation technique using a modified Clevenger apparatus (2 hours) and ...

The essential oil, obtained by steam distillation of flowers, leaves and stems from Wisteria brachybotrys Sieb.et Zucc, collected in Japan was analyzed by gas chromatography (GC) and GC-MS. The important aroma-active compounds were also detected in the oil using GC-MS/Olfactometry (GC-MS/O) and aroma extraction dilution analysis (AEDA). As a result, sixty-eight compounds from flowers of W. brac...

The chemical composition of essential oil obtained by hydrodistillation of the leaves of Pachira glabra Pasq., (PgEO) has been studied by Gas Chromatography (GC) and Gas Chromatography coupled with Mass Spectrometry (GC/MS). Thirty three constituents representing 98.4% of total contents were identified from the essential oil. The major constituents of oil were limonene (23.2%), β-caryophyllene ...

The chemical compositions of essential oils from the roots of Erigeron acris and Erigeron annuus were studied. The essential oils were obtained by hydrodistillation in 1.0% and 0.05% yield, respectively, and analyzed by GC, GC-MS. Fifty four and forty seven constituents were identified. Predominant constituents of both oils were poly-acetylene esters: (Z,Z)-matricaria ester (49.4% and 45.9%, re...

Hydro-distilled volatile oils from the leaves of Ocimum gratissimum L. (Lamiaceae) of 13 populations of different silvicultural zones were evaluated for antimicrobial activity against gram positive (Staphylococcus aereus, Bacillus spp.) and gram negative (Escherichia coli, Pseudomonas aeruginosa, Samonella typhi, Klebisiella pneumoniae, Proteus mirabilis) bacteria and a pathogenic fungus, Candi...
