Hydroxycinnamic acid amides from Iochroma cyaneum

Phytochemistry, 1990
Abstract Three hydroxycinnamic acid amides were isolated from the herb of Iochroma cyaneum and identified by means of spectral data and hydrolysis as caffeoylputrescine (paucine), feruloylputrescine (subaphylline) and the new N1,N10-di-dihydrocaffeoylspermidine.

Determination of hydroxycinnamic acids present in Rhododendron species

Phytochemistry, 2017
Hydroxycinnamates including free hydroxycinnamic acids and their chlorogenic acid derivatives and glycosides have been profiled in leaf extracts of 98 Rhododendron species using LC-MS techniques. In total, 69 hydroxycinnamic acid derivatives were identified in the leaves of 98 Rhododendron species.

Mechanisms of endothelial cell protection by hydroxycinnamic acids

Vascular Pharmacology, 2014
An endothelial dysfunction generates a proatherogenic environment characterized by stimulating thrombus formation. Epidemiological studies have provided evidence of a protective role of healthy diets in the prevention of cardiovascular diseases. Hydroxycinnamic acids constitute abundant polyphenols in our diets as they are present in high levels in ...

Hydroxycinnamic acid derivatives occurring in Cichorium endivia vegetables

Journal of Pharmaceutical and Biomedical Analysis, 2008
The hydroxycinnamic acid derivatives found in Chicorium endivia var. crispum and var. latifolium polyphenolic extracts were detected and characterized by high-performance liquid chromatography (HPLC) combined with photodiode array detector (DAD) and electrospray ionization-tandem mass spectrometry (ESI-MS/MS). The method provides data (molecular weight

Synthesis and Antioxidant Activity of Hydroxycinnamic Acid Xylan Esters

Journal of Agricultural and Food Chemistry, 2010
Naturally 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 ...

Sustainable Chemical Derivatization of Hydroxycinnamic Acids

ChemistrySelect
Abstract Green solvents like ethyl acetate and acetone convert hydroxycinnamic acids into natural and unnatural derivatives such as amides, esters, and other valuable synthetic intermediates. Employing as protection‐activation a system based on an alkyl chloroformate and N ...

Hydroxycinnamic Acids as Markers of Italian Blood Orange Juices

Journal of Agricultural and Food Chemistry, 1998
Extraction, 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, 1970
Abstract 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.

Hydroxycinnamic acid amide metabolism: physiology and biochemistry

Canadian Journal of Botany, 2002
Hydroxycinnamic acid amides (HCAAs) are a widely distributed group of plant secondary metabolites purported to function in several growth and developmental processes including floral induction, flower formation, sexual differentiation, tuberization, cell division, and cytomorphogenesis.
