Phenolic acids existed in many agricultural products especially vegetables and considered as important natural antioxidants. Eleven phenolic commonly were chosen to assess the antioxidant activities using DPPH·, ·ABTS+, ·O2-, ·OH scavenging assays, well ferric reducing power ?-carotene bleaching assays. The results showed that caffeic protocatechuic acid with simple dihydroxylation structures h...

This study investigated the effect of deficit irrigation at three management allowable depletion levels (MAD) 25%, 50%, and 75% on phytochemicals, ascorbic acid, antioxidant activity, glucose, fructose, and fresh and dry mass in two green leafy lettuce cultivars (Lollo Bionda and Vera) at harvest. Genotype response was observed during deficit irrigation on fresh and dry mass at harvest. Vera re...

This study investigated the similarities between Echinodorus macrophyllus and grandiflorus, plant species that are traditionally used in Brazil to treat rheumatism arthritis, whose anti-inflammatory effects supported by scientific evidence. The contents of cis- trans-aconitic acid, homoorientin, chicoric swertisin, caffeoyl-feruloyl-tartaric di-feruloyl-tartaric acid were quantified UPLC-DAD va...

In the present study, the Salmonella typhimurium tester strain TA 100 was used in the plate-incorporation test to examine the antimutagenic potential of caffeic, ferulic and cichoric acids extracted from plant species of genera Echinacea (L) Moench, as well as of another phenolic acids, on 3-(5-nitro-2-furyl)acrylic acid (5NFAA) and sodium azide mutagenicity. All tested compounds possess antimu...

Abstract The physical stability of protein-based emulsions depends on intra- and intermolecular interactions the interfacial protein-film. As studied in aqueous systems before, phenolic acid derivatives (PADs) non-covalently or covalently crosslink proteins depending pH-value thus, may impact protein-films. Whether these occur same manner at interface as water how they vary properties protein-f...

Abstract An analytical method was established to identify and quantify hydroxycinnamic acids, such as 1,5-dicaffeoylquinic acid (DCQA) chicoric (CA), in mixtures of Saussurea grandifolia Taraxacum coreanum (MST) by using reverse-phase high-performance liquid chromatography coupled with diode array detector (HPLC-DAD). Analyses were carried out an INNO C 18 column a gradient elution system, diff...
