We aimed at comparing the effects of domestication and extraction technique on chemical profiling antioxidant antimicrobial activities Rosmarinus officinalis essential oil (ROEO). This was isolated from wild (WR) cultivated rosemary (CR) using microwave-assisted (ME) Clevenger hydrodistillation (CH). Domestication main variability source in ROEO constituents, while yield equally determined by t...

The present study aimed to chemically characterize 31 accessions and seven cultivars of basil. The percentage composition of the essential oils of the accessions and cultivars was based on the 14 most abundant constituents: 1,8-cineole, linalool, methyl chavicol, neral, nerol, geraniol, geranial, methyl cinnamate, β-bourbonene, methyl eugenol, α-trans-bergamotene, germacrene-D, epi-α-cadinol, a...

The adsorption of α-pinene to solid surfaces is an important primary step during the chemical conversion of this common terpene over mesoporous materials, as well as during the formation of atmospheric aerosols. We provide evidence of tight and loose physisorbed states of α-pinene bound on amorphous SiO2 as determined by their adsorption entropy, enthalpy, and binding free energies characterize...

Chemical composition and bioactivity of essential oil from Salvia tomentosa Mill. natively grown in Bulgaria were investigated. GC-MS analysis identified 60 compounds which represented 98% of the oil constituents. The prevalent constituents were monoterpenes with eight dominant compounds being identified: borneol (10.3%), β-pinene (9%), camphor (7.9%), α-pinene (6%), camphene (4%), 1.8-cineole ...

The inhibition of enzymes involved in the breakdown of carbohydrates is considered a therapeutic approach to the management of type-2 diabetes. This study sought to investigate the effects of essential oil from clove bud on α-amylase and α-glucosidase activities. Essential oil from clove bud was extracted by hydrodistillation, dried with anhydrous Na2SO4 and characterized using gas chromatograp...

the composition of the essential oils of nepeta crispa willd. and n. menthoides boiss. and buhse (lamiaceae) was investigated by means of gas chromatography (gc) and gc- mass spectrometery (ms). 1, 8-cineole was the most abundant component in oils: nepeta crispa (71%) and n. menthoides (41.1%). in the oil of n. crispa, b-pinene (5%) and d-terpineol (4.1%) were found to be the major constituents...
