A sinapic acid ester from Boreava orientalis
Phytochemistry, 1994Abstract A new sinapic acid ester, 6- O -β- d -(2′- O -sinapoyl)glucopyranosyl β- d -(1,2- O -disinapoyl)glucopyranose, was identified from fruits of Boreava orientalis . Structural elucidation was carried out on basis of UV, mass, 1 H and 13 C NMR spectral data, including 2D shift correlation and selective INEPT experiments.

Ultraviolet spectroscopy of sinapoyl malate, an essential UV-B screening agent in plants, was carried out in the cold, isolated environment of a supersonic expansion to explore its intrinsic UV spectral properties in detail. Despite these conditions, sinapoyl malate displays anomalous spectral broadening extending well over 1000 cm(-1) in the UV-B ...

Sinapic acid is found in many edible plants and fruits, such as rapeseed, where it is the predominant phenolic compound. New sinapic acid phenethyl ester (SAPE) analogues were synthesized and screened as inhibitors of the biosynthesis of 5-lipoxygenase (5-LO) in stimulated HEK293 cells and polymorphonuclear leukocytes (PMNL).

A methyl ester of sinapic acid (MESA) has recently attracted attention due to its antioxidant action. This article presents results of a study on the spectral and physicochemical properties of MESA, using quantum chemistry (QC), steady-state (absorption and fluorescence), and time-resolved fluorescence techniques (TCSPC). The pKa of the phenol group in

Given the hepatotoxicity and an unfavorable pharmacokinetic profile of zileuton (Zyflo®), currently the only approved and clinically used 5‐Lipoxygenase (5‐LO) inhibitor, the search for potent and safe 5‐LO inhibitors is highly demanded. The action of several phenolic acid phenethyl esters as potential 5‐Lipoxygenase (5‐LO) inhibitors has been ...

Sinapic acid esters (SAE) are important antinutritional compounds of the seed of rapeseed (Brassica napus L.) and related Brassica species. The objective of this work was to study the potential of near infrared reflectance spectroscopy (NIRS) to analyze SAE content intact‐seed samples of the genus Brassica.

The seed of Brassica spp. contain high levels of sinapic acid esters (SAE). Because of their antiquality nature, the presence of SAE limits the use of Brassica meal as a source of high‐quality protein. The objective of this study was to search for material with reduced SAE content in Brassica spp.
