In our screening program for new agrochemicals from Chinese medicinal herbs, Murraya exotica was found to possess insecticidal activity against the maize weevil, Sitophilus zeamais and red flour beetle, Tribolium castaneum. The essential oil of aerial parts of M. exotica was obtained by hydrodistillation and investigated by GC and GC-MS. The main components of M. exotica essential oil were spat...

The aim of the present study was to investigate the volatile and sensorial profile of basil (Ocimum basilicum L.) by quantitative descriptive analysis (QDA) of the essential oil of three hybrids ("Cinnamon" × "Maria Bonita," "Sweet Dani" × "Cinnamon," and "Sweet Dani" × "Maria Bonita"). Twelve descriptive terms were developed by a selected panel that also generated the definition of each term a...

Fresh aerial parts of Angelica glauca, growing wild in Kashmir valley in higher Himalaya (Jammu and Kashmir, India), collected at flowering stage from different locations, on hydro-distillation provided a refreshing light pale coloured essential oil with characteristic floral woody flavour. The oil was found to be a complex mixture of mono- and sesquiterpenes and 34 compounds accounting for nea...

Hydrodistilled essential oil from Rhododendron anthopogonoides Maxim. (Ericaceae) aerial parts was analysed by gas chromatography-mass spectrometry (GC-MS). A total of 42 compounds, accounting for 95.48% of the total oil, were identified. The main constituents of the essential oil were benzyl acetone (34.41%), nerolidol (10.19%), 1,4-cineole (8.41%), beta-caryophyllene (5.63%), gamma-elemene (5...

ABSTRACT: Varronia curassavica is a medicinal species native to Brazil; its anti-inflammatory properties are attributed α-humulene and β-caryophyllene. This study investigated the population variability of V. curassavica. Leaves were collected from 40 individuals natural transferred glass flasks (2 mL). The volatiles extracted analyzed using static headspace gas chromatography coupled with mass...

Marrubium cuneatum Banks & Sol. is a perennial plant belonging to the Iran-Turan phytogeographical region, which distributed in limited region Middle East (Lebanon, Syria, Palestine, Turkey, Iraq and Iran). The chemical composition of essential oil (Lamiaceae) from Turkey was characterized. Hydro-distilled analysed simultaneously by gas chromatography (GC) chromatography-mass spectromet...

The genus Satureja is represented by fifteen species of which five are endemic and Satureja pilosa and S. icarica have recently been found as new records for Turkey. Aerial parts of the Satureja pilosa, S. icarica, S. boissieri and S. coerulea collected from different localities in Turkey were subjected to hydrodistillation to yield essential oils which were subsequently analysed by GC and GC/M...

ÐThe essential oils from Piper capense, P. nigrum, P. guineense and P. umbellatum from S. Tome e Prõ ncipe were investigated for the ®rst time. They were analysed by GC, GC-mass spectrometry and C NMR. Monoterpene hydrocarbons were the main group of constituents in three of the samples (P. capense, P. nigrum and P. umbellatum), whereas for the other species (P. guineense) phenylpropanoid deri...
