Energetics of neutral and deprotonated (Z)-cinnamic acid
(Academic Press Ltd - Elsevier Science Ltd, 2016-01)
We have performed a study of structural, thermochemical and thermophysical properties of the (Z)-cinnamic acid neutral molecule and its corresponding oxyanion (formed by deprotonation of the carboxylic group). The ...
Molecular structure, experimental and theoretical 1H and 13C NMR chemical shift assignment of cyclic and acyclic α,β-unsaturated esters
(John Wiley & Sons Ltd, 2014-01)
The experimental 1H and 13C NMR spectra of 13 phenyl cinnamates and four 4-methylcoumarins were investigated and their chemical shifts assigned on the basis of the two-dimensional spectra. For the unsubstituted cinnamic ...
Metabolite characterization of fifteen by-products of the coffee production chain: From farm to factory
(2022-02-01)
Approximately 11.4 million tonnes of solid by-products and an increased amount of waste water will be generated during the 2020/21 coffee harvest. There are currently no truly value-adding uses for these potentially ...
Effects of allelochemicals from tobacco root exudates on seed germination and seedling growth of tobacco
(Allelopathy Journal, 2014-01)
The composition of root exudates from two varieties (K 326 and NC 89) of tobacco were identified by GC-MS. Organic acids,amides and esters were the main constituents of the root exudates which differed in their qualitative ...
