Extraction and mass transfer study of Cupressus sempervirens L. oil by hydro-distillation method

Gamma-irradiation effect on the chemical composition and antibacterial activity of the moroccan tanacetum annuum L. essential oil

“…According to the (British pharmacopoeia 1993) [ 17 ] and the (European pharmacopoeia 2005) [ 18 ], a hydro-distillation procedure employing a Clevenger type apparatus was approved for the extraction of essential oils (EOs) [ 19 ]., based on this technique and following extraction, the EO samples were subjected to drying over anhydrous sodium sulfate and stored in opaque glass vials at a refrigerated temperature of 4 °C until further use. The chemical composition of EOs is same across all samples thanks to the standardization of the extraction procedure.…”

Bioactive compounds, pharmacological actions and pharmacokinetics of Cupressus sempervirens

“…This cypress oil was extracted by using the hydrodistillation method, using a clevenger apparatus. Cupressus sempervirens leaves were collected from Hit city in Al-Anbar province-Iraq (Hamid et al 2021). The influences of three important parameters on the process of oil extraction, water which is used as a solvent to the solid ratio (5:1 and 14:1 (ml solvent/g plant)), temperature (30 to 100 °C) and processing time, were examined to obtain the best processing conditions to achieve the maximum yield of the essential oil.…”

“…The influences of three important parameters on the process of oil extraction, water which is used as a solvent to the solid ratio (5:1 and 14:1 (ml solvent/g plant)), temperature (30 to 100 °C) and processing time, were examined to obtain the best processing conditions to achieve the maximum yield of the essential oil. Therefore, the best conditions, which were obtained from a study, were at 4 h as a reaction time, the temperature of about 100 °C and solvent to solid ratios of 10:1 ml solvent/g plant (Hamid et al 2021). The volumetric mass transfer coefficient at ratios 10:1 and 14:1 solvent to solid ratio were 0.017 and 0.007 min respectively.…”

“…Thus, it took less time to extract the Cupressus sempervirens oil by using the 10:1 compared to using 14:1 solvent to solid ratio. The composition compounds of extracted C. sempervirens L. essential oil were analyzed and identified by gas chromatography mass spectrometry (GC-MS) (Hamid et al 2021).…”
