Phenolic substances in barley.

The occurrence of phenolic substances in arthropods.

Barley phenolic compounds impedes oxidative stress in lead acetate intoxicated rabbits

Capillary electrophoretic determination of selected phenolic compounds in humic substances of well waters and fertilizers.

Humic substances (HS) from well waters, fertilizers, and synthetic phenolic polymers were characterized by elemental and UV-VIS spectroscopic analyses. Capillary zone electrophoresis (CZE) with UV absorption detection was used to analyze the lignin-derived phenolic distribution in the degradation residues after alkaline CuO oxidation of HS samples. Eleven phenols with p-acetyl, vanillyl and syr...

Ocean Acidification and the Loss of Phenolic Substances in Marine Plants

Rising atmospheric CO(2) often triggers the production of plant phenolics, including many that serve as herbivore deterrents, digestion reducers, antimicrobials, or ultraviolet sunscreens. Such responses are predicted by popular models of plant defense, especially resource availability models which link carbon availability to phenolic biosynthesis. CO(2) availability is also increasing in the o...

Multidimensional fluorescence studies of the phenolic content of dissolved organic carbon in humic substances.

Indicators suggest that the amount of dissolved organic carbon (DOC) in natural waters may be increasing. Climate change has been proposed as a potential contributor to the trend, and under such a mechanism, the phenolic content of DOC may also be increasing. This study explores the assessment of the phenolic character of DOC using multidimensional fluorescence spectroscopy as a more convenient...
