(1993)The concentration of the triterpene oleanolic acid in leaves of Baccharis linearis varies at different stages of plant growth from 1.9 to 3.0 g kg-1 fr. wt. Larvae of Heliothis zea, starved with 1.4 mg of oleanolic acid ...
-
(Institution of Chemical Engineers, 2017)Olive leaves extract (OLE) was microencapsulated with inulin (OLE-IN) by spray-drying using a central composite design. Oleuropein encapsulation efficiency and recovery values were over 87% in the OLE-IN microparticles ...
-
(2014)We show that the Gel’fand character χG of a finite group G (i.e. the sum of all irreducible complex characters of G ) may be realized as a “ twisted trace” g 7→ T r(ρg ◦ T ) for a suitable involutive linear automorphism ...
-
(Informa Healthcare, 1989)The characteristics of the visible luminescence that follows the lipid peroxidative process were investigated either in the autoxidation of rat brain homogenates or in the azo-bis-arnidinopropane initiated lipid peroxidation ...
-
(Royal Society of Chemistry, 2005)The new hybrid organic-inorganic copper oxovanadium phosphates of composition Cu4(bipy)4V4O11(PO 4)2·nH2O (n ∼ 5) (1) and Cu 2(bipy)2V2P2O12 (2) (bipy = 2, 2′-bipyridine) adopting the triclinic symmetry were obtained by ...
-
(Sociedade Brasileira de Química, 2010)Substituted chromenos, dihydropyridines and pyridines have been important in the syntheses of compounds having interesting pharmacological properties. Therefore, we found of interest to synthesize chromenopyridines and ...

On the reduction of 4-oxo-4H-benzopyran-3-carbaldehydes: Global and local electrophilicity patternse (SOCIEDAD CHILENA DE QUIMICA, 2004-03)The theoretical global and local electrophilicity patterns of substituted and chelated 4-oxo-4H-benzopyran-3-carbaldehydes (formylchromones) have been evaluated using the electrophilicity index proposed by Parr et al [J. ...
-
(2012)The formation of paramagnetic species from oncocalyxone A in aprotic medium was confirmed by performing in situ electrochemical-electron spin resonance (E-ESR) experiments. The high delocalization of the radical generated ...
