The effects of hydroxycinnamic acid derivatives on adiponectin secretion
Phytomedicine, 2009Adiponectin is positively correlated with insulin sensitivity. Hydroxycinnamic acid derivatives (HADs), observed ubiquitously in plants, have some physiological functions. In this study, we investigated the effect of HADs on serum adiponectin concentrations in mice and on adiponectin secretion of 3T3-L1 adipocytes.

Synthesis and Antioxidant Activity of Hydroxycinnamic Acid Xylan Esters
Journal of Agricultural and Food Chemistry, 2010Naturally occurring hydroxycinnamic acids, such as ferulic and sinapic acids, are known to possess antioxidant activity. In this study, ferulic acid and sinapic acid were covalently attached to oat spelt arabinoxylan and birch wood glucuronoxylan by esterification in a two-step feasible synthesis to generate modified xylans with various degrees of ...

ANODIC OXIDATION OF 4-HYDROXYCINNAMIC ACIDS
Chemistry Letters, 1979Abstract Anodic oxidation of 4-hydroxycinnamic acids was carried out at a controlled potential vs. SCE (+900 or 840 mV), using an undivided cell, to afford the corresponding asatone or isoasatone-type compound as well as pinoresinol-type dilactones.

Hydroxycinnamic Acids as Markers of Italian Blood Orange Juices
Journal of Agricultural and Food Chemistry, 1998Extraction, resolution, and determination of the trans-hydroxycinnamic acids (caffeic, p-coumaric, ferulic, and sinapic) were performed in 82 orange juices derived from the most important blood and blond varieties grown in Italy. Soluble solids, acidity, and anthocyanins were also determined.

Hydroxycinnamic acid derivatives of rheum rhaponticum
Phytochemistry, 1970Abstract Further work on the polyphenols of Rheum rhaponticum has led to the isolation of a range of hydroxycinnamic acid derivatives. Compounds identified were the 1-glucose esters of ferulic, sinapic and p -coumaric acids. Several other feruloyl derivatives were found, some of which must have complex structures.
