Simplified Preparation of Coniferyl and Sinapyl Alcohols

Journal of Agricultural and Food Chemistry, 2005
Coniferyl and sinapyl alcohols were prepared from commercially available coniferaldehyde and sinapaldehyde using borohydride exchange resin in methanol. This reduction is highly regioselective and exceptionally simple, making these valuable monolignols readily available to researchers lacking synthetic chemistry expertise.

Coniferyl alcohol oxidase ? a catechol oxidase?

Trees, 1995
The physico-chemical properties of coniferyl alcohol oxidase (CAO), a copper containing glycoprotein spatiotemporally associated with lignification in conifers, is reported here. By electron paramagnetic resonance spectroscopy, only type 3 copper was indicated in CAO. CAO oxidizes several laccase substrates; however, it is not a blue-copper protein and

Capillary Zone Electrophoresis of Coniferyl Alcohol Oxidation Products

Journal of Agricultural and Food Chemistry, 2001
Capillary zone electrophoresis (CZE) was developed for the quantitative determination of dimers obtained by horseradish peroxidase-catalyzed oxidation of coniferyl alcohol. The influence of pH, electrolyte concentration, applied voltage, and temperature on CZE performance was investigated, resulting in an efficient and rapid separation.

Coniferyl alcohol metabolism in conifers — I. Glucosidic turnover of cinnamyl aldehydes by UDPG: coniferyl alcohol glucosyltransferase from pine cambium

Phytochemistry, 2001
UDPG: coniferyl alcohol glucosyltransferase (CAGT; EC 2.4.1.111) isolated from cambial tissues of Pinus strobus was able to convert cinnamyl aldehydes as well as dihydroconiferyl alcohol into their corresponding 4-O-beta-D-glucosides in vitro. Cinnamyl aldehydes were glucosylated with comparable efficiency to coniferyl alcohol, the physiological ...

Free radicals of coniferyl alcohol and isoeugenol

Australian Journal of Chemistry, 1975
E.s.r, spectra have been obtained from the free radicals formed by photolysis of coniferyl alcohol and isoeugenol in low temperature ice matrices. Analysis of these spectra indicates that the unpaired electrons are delocalized over the entire radicals and the spin densities at the β carbon atoms are about a third of an electron.

Thermolytic decomposition of coniferyl alcohol

Journal of Analytical and Applied Pyrolysis, 1992
Abstract Thermolytic decomposition of coniferyl alcohol was studied at temperatures between 200°C and 275°C under an inert atmosphere, to shed more light on the initial thermal reactions in the thermochemical conversion of lignin. In this temperature range, dimerization and oligomerization reactions dominate, while side chain CC bond scission ...

Bacterial degradation of dehydropolymers of coniferyl alcohol

Archives of Microbiology, 1984
A bacterial isolate identified as Xanthomonas sp. proved to be ligninolytic due to its ability to degrade 14C-labeled dehydropolymers of coniferyl alcohol (DHP) and [14C]lignocellulose complexes from corn plants (Zea mays). Several parameters of ligninolysis were evaluated and it was shown that resting cells degrade DHP as sole carbon source ...
