Dissolution of lignocellulosic materials and its constituents using ionic liquids - a review
The state of art from the dissolution of cellulose, lignin and wood using ionic liquids is presented in this work. The emphasis is put on the relationship between the properties of ionic liquids andExpand
Quantification of a broad spectrum of lignans in cereals, oilseeds, and nuts.
7-Hydroxymatairesinol, which has not previously been detected in cereals because of destructive extraction methods, was the dominant lignan in wheat, triticale, oat, barley, millet, corn bran, and amaranth whole grain. Expand
Antioxidant activity of knotwood extractives and phenolic compounds of selected tree species.
The antioxidant potency and the radical scavenging capacity of superoxide and peroxyl radicals were assessed for 13 hydrophilic knotwood extracts of commercially important wood species, or fractionsExpand
Identification of lignans by liquid chromatography-electrospray ionization ion-trap mass spectrometry.
A versatile method for analyses of lignans was developed using LC separation on a C8 column followed by fragmentation and detection of ions produced in the ion trap, and several compound-specific fragmentations were observed and used for identification of individual compounds. Expand
Structural determinants of plant lignans for the formation of enterolactone in vivo.
It is confirmed that the absolute configurations at C8 and C8' are not changed during the microbial metabolism, whether the biological effects are enantiomer-specific, remains to be resolved. Expand
Pinoresinol-lariciresinol reductases with different stereospecificity from Linum album and Linum usitatissimum.
A cDNA encoding pinoresinol-lariciresinol reductase (PLR) from L. album was isolated to get more insight into the mechanism of (-)- and (+)-secoisolaricires inol biosynthesis, respectively. Expand
Complete assignments of the (1)H and (13)C chemical shifts and J(H,H) coupling constants in NMR spectra of D-glucopyranose and all D-glucopyranosyl-D-glucopyranosides.
To support the experimental results, the (1)H and (13)C chemical shifts and the spin-spin coupling constants between the non-hydroxyl protons of alpha- and beta-d-glucopyranose (1a and 1b) were calculated with density functional theory (DFT) methods at the B3LYP/pcJ-2//B3LYp/6-31G(d,p) level of theory.

Characterisation of water-soluble galactoglucomannans from Norway spruce wood and thermomechanical pulp
Abstract Different fractions of water-soluble polysaccharides, all composed mainly of acetyl-galactoglucomannans, from native Norway spruce wood and thermomechanical pulp were isolated andExpand
Acetylation and characterization of spruce (Picea abies) galactoglucomannans.
NMR studies indicated migration of acetyl groups from O-2 or O-3 to O-6 after a heating treatment in a water bath, and the thermal stability of the products was investigated by DSC-TGA. Expand
Inhibition of Akt signaling by the lignan matairesinol sensitizes prostate cancer cells to TRAIL-induced apoptosis
Of the three tested lignan molecules, matairesinol (MAT) was the most effective as a death receptor-sensitizing agent and targeting this survival pathway with MAT could markedly benefit TRAIL-based tumor therapies, including those aimed at prostate cancer. Expand
