New Glycosides of Lignin
نویسندگان
چکیده
New biodegradable surface active agents were prepared by glycosidation of prehydrolysis lignin with the D-glucose using anhydrous ferric chloride as the catalyst which afforded polymeric alkyl, benzyl and aryl glucofuranoside derivatives of lignin. Moreover, a series of novel lignin-based surface active agents was obtained by subsequent Oxidation of the primary alcohol groups of u-glucose into carboxyl groups by 2,2,6,6,-tetramethyl1-piperidine oxoammonium ions with sodium hypochlorite and sodium bromide in an aqueous alkaline Solution at pH 11.

Systemic induction of phloem secondary metabolism and its relationship to resistance to a canker pathogen in Austrian pine.
The mechanisms and conditions affecting expression of systemic induced resistance (SIR) in pine are not clearly understood. Two hypotheses were tested here: that SIR against a pathogen induced by either a pathogen or an insect involves coordinated shifts in phloem secondary metabolism; and that fertility affects the production of these compounds. To test these hypotheses, a tripartite system wa...
متن کاملChemical characterization of lignin and lipid fractions in kenaf bast fibers used for manufacturing high-quality papers.
The chemical composition of lignin and lipids of bast fibers from kenaf (Hibiscus cannabinus) used for high-quality paper pulp production was studied. Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) of fibers showed a lignin with a high syringyl/guaiacyl ratio (5.4) and minor amounts of p-hydroxyphenyl units. Simultaneously, sinapyl and coniferyl acetates were also identified, indicat...

A new iridoid glucoside, 10-methoxy apodanthoside (1), and a new monoterpene glycoside, (3S,6S)-cis linalool-3,7-oxide O-β-D-glucopyranosyl-(1"-->5')-β-D- xylofuranoside (2), were isolated from V. edulis (Rubiaceae), along with eighteen known compounds (3-20), including monoterpenes, iridoid glycosides, and a lignin, which were encountered for the first time in the genus Vangueria,. The structu...
متن کاملFlavonoid accumulation in Arabidopsis repressed in lignin synthesis affects auxin transport and plant growth.
In Arabidopsis thaliana, silencing of hydroxycinnamoyl-CoA shikimate/quinate hydroxycinnamoyl transferase (HCT), a lignin biosynthetic gene, results in a strong reduction of plant growth. We show that, in HCT-silenced plants, lignin synthesis repression leads to the redirection of the metabolic flux into flavonoids through chalcone synthase activity. Several flavonol glycosides and acylated ant...
متن کاملCO2 enrichment and carbon partitioning to phenolics: do plant responses accord better with the protein competition or the growth-differentiation balance models?
Rising levels of atmospheric CO2 can alter plant growth and partitioning to secondary metabolites. The protein competition model (PCM) and the extended growth/differentiation balance model (GDBe) are similar but alternative models that address ontogenetic and environmental effects on whole-plant carbon partitioning to the phenylpropanoid biosynthetic pathway, making many divergent predictions. ...
