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. ...
Chemical composition, antioxidant and antimicrobial activity of Thymus praecox supercritical extracts
(Elsevier Science Bv, Amsterdam, 2016)
The chemical composition, antimicrobial and antioxidant activity of Thymus praecox extracts obtained by fractional supercritical fluid extraction (SFE) with carbon dioxide were investigated. Properties of supercritical ...
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 ...
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 ...
