Modelling and optimization of supercritical CO2 extraction of St. John's Wort (Hypericum perforatum L.) using genetic algorithm
(Elsevier Science Bv, Amsterdam, 2012)
Modelling and optimization of the extraction of St. John's Wort using supercritical fluid is the subject of this study. Applying conservation of mass, two partial differential equations were written for solute concentration ...
Supercritical and high pressure subcritical fluid extraction from Lemon balm (Melissa officinalis L., Lamiaceae)
(Elsevier, Amsterdam, 2016)
Analysis of yield and composition profile of Melissa officinalis (Lemon balm) extract obtained by two-step CO2 extraction at high pressure was analyzed. The first or essential oil fraction, collected at 10 MPa and 40 degrees ...
Supercritical impregnation of cellulose acetate with thymol
(Elsevier Science Bv, Amsterdam, 2015)
Present work was aimed to investigate supercritical solvent impregnation of thymol into cellulose acetate in order to explore the possibility of developing a new functionalized solvent-free material with antimicrobial ...
Supercritical carbon dioxide extraction of Trigonella foenum-graecum L. seeds: Process optimization using response surface methodology
(Elsevier Science Bv, Amsterdam, 2016)
Pretreatment of fenugreek (Trigonella foenum-graecum L, Fabaceae) seeds was achieved using the step of defatting and acid hydrolysis. The obtained hydro-isolate (HI) was used as initial feed for diosgenin isolation by ...
Optimization of supercritical CO2 extraction of fenugreek seed (Trigonella foenum-graecum L.) and calculating of extracts solubility
(Elsevier Science Bv, Amsterdam, 2016)
Supercritical CO2 (SC-CO2) extraction of fenugreek seeds (Trigonella foenum-graecum L, Fabaceae) was analyzed using different pressure and temperature (16.6-33.4 MPa and, 30-50 degrees C), which corresponded to SC-CO2 ...
Supercritical fluid extraction of curry flowers, sage leaves, and their mixture
(Elsevier, Amsterdam, 2013)
Yield and composition of curry flower (Helichrysum italicum) and sage leaves (Salvia officinalis) extract obtained by supercritical CO2 extraction (SFE) at 15 MPa and 40 degrees C were analyzed and compared to composition ...
Supercritical CO2 sorption kinetics and thymol impregnation of PCL and PCL-HA
(Elsevier, Amsterdam, 2016)
The potential of supercritical carbon dioxide (scCO(2)) processing of polycaprolactone (Pa) and polycaprolactone-hydroxyapatite (PCL-HA) composites for obtaining functional porous scaffolds at moderate temperatures (35-40 ...
Utilization of supercritical carbon dioxide in fabrication of cellulose acetate films with anti-biofilm effects against Pseudomonas aeruginosa and Staphylococcus aureus
(Elsevier Science Bv, Amsterdam, 2018)
This study discusses utilization of supercritical carbon dioxide for impregnation of cellulose acetate films with thymol in order to produce material with anti-biofilm activity against Pseudomonas aeruginosa and Staphylococcus ...
Antioxidant and cytotoxic activity of fatty oil isolated by supercritical fluid extraction from microwave pretreated seeds of wild growing Punica granatum L.
(Elsevier Science Bv, Amsterdam, 2018)
Pomegranate seeds are an excellent source of compounds with biological activity. In the present study, the pomegranate seed oil (PSO) was tested for antioxidant and cytotoxic potential. PSO was extracted by super-critical ...
Impregnation of corona modified polypropylene non-woven material with thymol in supercritical carbon dioxide for antimicrobial application
(Elsevier Science Bv, Amsterdam, 2015)
This study discusses the possibility of impregnation of polypropylene (PP) and corona modified PP non-woven material with thymol in supercritical solvent in order to fabricate eco-friendly antimicrobial textile material. ...
