Characterization of galactooligosaccharides derived from lactulose

Stability of Oligosaccharides Derived from Lactulose

Evaluation of Anti-Wrinkle Effects of DuOligo, Composed of Lactulose and Galactooligosaccharides

Currently, alternatives to prebiotics for skin treatment are receiving much interest. However, little is known about the efficacy of topically applied prebiotics in skin anti-aging. This study was conducted to observe the anti-aging effects of DuOligo, which is composed of lactulose and galactooligosaccharides (GOS). We investigated wrinkle-related parameters by quantitative and qualitative ski...

Synthesis of Oligosaccharides Derived from Lactulose (OsLu) Using Soluble and Immobilized Aspergillus oryzae β-Galactosidase

β-Galactosidase from Aspergillus oryzae offers a high yield for the synthesis of oligosaccharides derived from lactulose (OsLu) by transgalactosylation. Oligosaccharides with degree of polymerization (DP) ≥ 3 have shown to possess higher in vitro bifidogenic effect than di- and tetrasaccharides. Thus, in this work, an optimization of reaction conditions affecting the specific selectivity of A. ...

Synthesis and characterization of some transition metal complexes of Schiff base derived from 2,4 - dihydroxybenzaldehyde

Abstract New N2O2 type Schiff base has been designed and synthesized by condensing 2,4 dihydroxy benzaldehyde and α-naphthylamine in ethanol. Solid metal complexes of the schiff base with Cu(II), Ni(II) and Zn(II) metal ion were synthesized and characterized by elemental analysis, magnetic susceptibility, molar conductance, IR, UV-Vis and ‘H NMR spectral studies. The data shows that the c...

Synthesis and characterization of Schiff-base polymer derived from 2,5-dichloroaniline and 2-hydroxybenzaldehyde

Schiff base sal-2,5-Clan = 2-(2,5-dichlorobenzylideneamino)phenol used as a new precursor for preparation of poly-2-(2,5-dichlorobenzylideneamino)phenol (PDCBAP). In an aqueous alkaline medium, NaOCl oxidant is capable of oxidative poly-condensation reaction (OP). Both sal-2,5-Clan and PDCBAP were characterized by solubility tests, FT-IR, 1H-NMR spectroscopy and TG-DTA studies. FT-IR and 1H-NMR...
