Alkaloids from Chelidonium majus L.: Fractionated supercritical CO2 extraction with co-solvents
(Elsevier Science, 2016-06)
Chelidonium majus L. is rich in many isoquinoline alkaloids which are responsible for the anti-inflammatory, antitumor and cytotoxic bioactivities known for this plant. The main alkaloids identified in C. majus L. include ...
Solvent, coordination and hydrogen-bond effects on the chromic luminescence of the cationic complex [(phen)(H2O)Re(CO)(3)]
(Royal Society of Chemistry, 2016)
The [(phen)((HO)-O-2)Re(CO)(3)](+)(CF3SO3)(-) salt, 1(+)(CF3SO3-), has been crystallized in the form of two new solvates, [(phen)(H2O)Re(CO)(3)](+)(CF3SO3)(-)center dot(C4H8O)(0.5) and [(phen)(H2O)Re(CO)(3)](+)(CF3SO3)(-)center ...
Improving the enantioselective bioreduction of aromatic ketones mediated by Aspergillus terreus and Rhizopus oryzae: the role of glycerol as a co-solvent
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
The improvement of the enzymatic performance of Aspergillus terreus and Rhizopus oryzae in enantioselective bioreductions by using glycerol as a co-solvent has been studied. In the most of the bioreductions, glycerol has ...
Supercritical carbon dioxide extraction of cannabinoids from Cannabis sativa L.
(Elsevier Science, 2017-11)
Cannabis sativa L. extracts with high concentration of δ9-tetrahydrocannabinolic acid (THCA) and δ9-tetrahydrocannabinol (THC) were obtained by supercritical carbon dioxide (CO2) extraction. The objective of this work was ...
Poly(hydroxybutyrate-co-hydroxyvalerate) microspheres loaded with atrazine herbicide: screening of conditions for preparation, physico-chemical characterization, and in vitro release studies
(Springer, 2011-07-01)
Due to their widespread use in agriculture as well as in urban areas, agricultural chemicals are globally some of the most commonly encountered substances in waters. The objective of this study is to develop (including ...
Basicity and solvent effects on hydrogen bonding in NR3 ⋯ HCOOH (R = H, CH3) model systems
(John Wiley and Sons Inc., 1999)
The effect of the basicity of methyl-amines on hydrogen bonding (HB) with HCOOH is examined in both gas and solution phases. In the gas phase, the strength of HB may be related to the proton affinity (PA) difference between ...
Sensitive determination of water insoluble dyes used as marking of commercial petroleum products using high-performance liquid chromatography with electrochemical detection
(2010-05-01)
This paper describes an analytical method using high-performance liquid chromatographic (HPLC) separation coupled with electrochemical detection to detect three dyes, Solvent Blue 14 (SB-14), Solvent Blue 35 (SB-35) and ...

Ethane as an alternative solvent for supercritical extraction of orange peel oils
(Elsevier Science, 2008-12)
The objective of this study was to investigate the superiority of ethane in comparison to CO2 as a supercritical extraction solvent for deterpenating citrus oils. A rigorous computer code was developed that optimized ...
