Sinapoylmalate is one of the major phenylpropanoid metabolites that is accumulated in the vegetative tissue of Arabidopsis thaliana. A thin-layer chromatography-based mutant screen identified two allelic mutant lines that accumulated sinapoylglucose in their leaves in place of sinapoylmalate. Both mutations were found to be recessive and segregated as single Mendelian genes. These mutants defin...

In the last decades, ferroptosis and its relationship with Parkinson’s disease have gained significant attention. Compounds that affect iron-dependent pathways in particular, possible candidates for study this context.Sinapic acid is an iron-chelator high antioxidant bioactive phenolic acid. Its neuroprotective action, due to capacity, has been shown several experimental models.However, between...

Hydroxycinnamic acid derivatives (HCAs) are a group of naturally occurring polyphenolic compounds which possess various pharmacological activities. In this work, the interactions of bovine serum albumin (BSA) with six HCA derivatives, including chlorogenic acid (CHA), caffeic acid (CFA), m-coumaric acid (m-CA), p-coumaric acid (p-CA), ferulic acid (FA) and sinapic acid (SA) have been investigat...

Red radish (Raphanus L.) pickles are popular appetizers or spices in Asian-style cuisine. However, tons of radish brines are generated as wastes from industrial radish pickle production. In this study, we evaluated the dynamic changes in colour properties, phenolics, anthocyanin profiles, phenolic acid composition, flavonoids, and antioxidant properties in radish brines during lactic acid ferme...

Bi-specific OMT (EC 2.1.1.68) catalyzes the meta-specific methylation of caffeic acid and 5-hydroxyferulic acid to ferulic acid and sinapic acid, respectively (Higuchi, 1990). It is one of the key enzymes in angiosperm dicots mediating the formation of unique precursors for syringyl lignin, which is generally absent in gymnosperms (Higuchi, 1990). OMT has been purified and its cDNA clones isola...

Purpose: To determine the phenolic constituents as well as anti-proliferative, antioxidant and ironchelating activities of the leaf and rhizome extracts of Phymatopteris triloba. Methods: Concentrations of selected hydroxybenzoic acids, hydroxycinnamic acids and flavonoids in aqueous extracts were quantified using high performance liquid chromatography (HPLC). Antiproliferative activity was ass...
