A New Age for Quercus spp. Fruits: Review on Nutritional and Phytochemical Composition and Related Biological Activities of Acorns [PDF]

open access: yes, 2016
The current global food system must adapt to the expected growth of world population (about 9 billion individuals by 2050). This adaptation will probably include an increased consumption of edible wild foods, due to their richness in micronutrients and ...

Novel hydrolyzable tannins from Nuphar Japonicum DC.

open access: yesChemical and Pharmaceutical Bulletin, 1982
Two gallotannins (I and II) and an ellagitannin (III) named nupharin A have been isolated from Nuphar japonicum DC. (Nymphaeaceae). On the basis of chemical and spectral evidence, the structures of I, II and III were characterized as 1, 2, 6-tri-O-galloyl-α-D-glucose, 1, 2, 3, 4, 6-penta-O-galloyl-α-D-glucose and 1, 2, 6-tri-O-galloyl-3, 4-(S ...

Polyphenolic Activation of Basophils Explains Alcohol Hypersensitivity in AERD

open access: yesThe Laryngoscope, EarlyView.
The mechanism behind alcohol sensitivity in AERD has not been previously characterized. This study demonstrates the activation of basophils in patients with CRSwNP and AERD by polyphenolic compounds, but not ethanol. Since these compounds can be found in alcoholic beverages in similar frequencies by which they trigger symptoms, this research provides a

Tannin Fingerprinting in Vegetable Tanned Leather by Solid State NMR Spectroscopy and Comparison with Leathers Tanned by Other Processes

open access: yesMolecules, 2011
Solid state 13C-NMR spectra of pure tannin powders from four different sources – mimosa, quebracho, chestnut and tara – are readily distinguishable from each other, both in pure commercial powder form, and in leather which they have been used to tan ...

Powdered Hide Model for Vegetable Tanning II: Hydrolyzable Tanni [PDF]

open access: yes, 2015
Vegetable tannages employ both condensed and hydrolyzable tannins. As part of our exploration of tanning mechanisms, we reported previously on interactions of the condensed tannin, quebracho, with powdered hide.

Bottom–up and top–down drivers influence urbanization effects on insect herbivory in oaks

open access: yesOikos, EarlyView.
Urban forests provide essential ecosystem services, including pest control, biodiversity conservation, and human health benefits. Herbivory is a widespread biotic interaction that shapes ecosystem functions, such as primary productivity and soil fertility, which underpin these services.

From fertilizer to insecticide: urban leaf litter chemistry alters the survival landscape of Aedes aegypti

open access: yesPest Management Science, EarlyView.
Chemical profiling and bioassays reveal that leaf‐litter leachates from urban trees flip between nourishing and killing Aedes aegypti larvae: dilute Tipuana tipu boosts growth, whereas concentrated, aged extracts are >90% lethal. Species‐specific chemistry thus turns street trees into potential self‐renewing tools for integrated vector control ...
