The residues obtained after hydrodistillation of three aromatic plants (Calamintha grandiflora, Myrrhis odorata and Tussilago farfara) were separated into solid and liquid fractions. The liquid fraction was dried while the solid fraction was extracted with acetone, methanol or ethanol. Two main types of antioxidant activity tests were employed: i) assays to evaluate oxidation of fats, oils and ...

Pressurized hot water extraction (PHWE) and hydrodistillation were compared for the extraction of essential oil from Lavandin. Using GC-FID analysis in conjunction with central composite design, the maximum extraction yield was obtained for temperature of 148 o C, pressure of 33.7 (bar), static time of 10.7 (min), dynamic time of 17.6 (min), and flow rate of 0.69 (mL/min). The PHWE is a practic...

abstract: chemical composition of lavandula angustifolia was studied by solvent free microwave extraction (sfme) and hydrodistillation (hd) methods. 1, 8-cineole (42.7% and 37.9%), camphor (26.1% and 21.3%) and borneol (31.2% and 21.6%) were the major compounds that obtained by sfme and hydrodistillation, respectively. the antibacterial activity of extracted oils was investigated against gram-p...

An ionic liquid-based ultrasonic/microwave-assisted simultaneous distillation and extraction (IL-UMASDE) method for isolating camptothecin (CPT), 10-hydroxycamptothecin (HCPT), vincoside-lactam (VCS-LT), and essential oils (EOs) from Camptotheca acuminata Decne fruits was developed. The important parameters were optimized using single-factor and central composite design experiments. The optimum...

The extraction of essential oils from Lemongrass leaves (Cymbopogon nardus L.) has become more promising than ever before due to the oils' increasing demand in market addition dynamic breakthrough its technology advancement. This study presents a comparison two different methods microwave-assisted oil extraction, namely Microwave Hydrodistillation (MHD) and Solvent-Free Extraction (SFME), both ...

Essential oils are considered as very complex natural mixtures containing numerous components at quite various concentrations. Lythrum salicaria has not been previously subjected to examination of its volatile oil. The present study was carried out to evaluate the essential oil composition of the flowering aerial parts of the plant by using conventionally hydro-distillation (HD) and microwave a...

The present study examines the possible antibacterial mechanism of action of the essential oil obtained from Chamaecyparis obtusa (COEO) sawdust against foodborne pathogenic bacteria. The COEO was obtained by microwave-assisted hydrodistillation of C. obtusa sawdust. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of COEO against the tested foodbor...
