Plant bioactive metabolites play a pivotal role in protection against environmental stresses and offer great potential for nutraceutical exploitation. In this sense, halophytes present an exceptional opportunity sustainable saline agriculture since they can massively accumulate under stressful conditions. We investigated the responses of halophyte Crithmum maritimum to increasing salinity, nutr...

Date palm seed oil is among the precious vegetable oils with low yield, whose extraction commonly done organic solvents which cause serious problems. This study aims to assess effectiveness of orange peel essential as biosolvent for date extraction. Green was conducted by Soxhlet apparatus well soaking and compared method using petroleum ether. The GC-MS analysis confirmed its richness limonene...

in chlorogenic acid (5-caffeoylquinic acid) (Fig 1). Coffee, one of the most widely consumed beverages in the world, is the major dietary source of chlorogenic acids. Chlorogenic acid has antioxidant properties as shown by its ability to scavenge various free radicals when tested in vitro (3-5). Moreover, chlorogenic acid reduces glucose uptake by favouring the dissipation of the Na+ electroche...

Chlorogenic acid is a well known natural product with important bioactivities. It contains an ester bond formed between the COOH of caffeic acid and the 3-OH of quinic acid. We synthesized a chlorogenic acid analogue, 3α-caffeoylquinic acid amide, using caffeic and quinic acids as starting materials. The caffeoylquinc acid amide was found to be much more stable than chlorogenic acid and showed ...

in this study, caffeic acid (ca) and its three derivatives including 3-caffeoylquinic acid (3-cqa, neochlorogenic acid), 4-caffeoylquinic acid (4-cqa, cryptochlorogenic acid), and 5-caffeoylquinic acid (5-cqa, chlorogenic acid) were identified in bupleurum chinense aerial parts using reverse-phase high-performance liquid chromatography (rp-hplc) with photodiode array (pda) detector, reference c...

China is one of the most important centers of diversity for Eriobotrya japonica Lindl. in the world. In this study, seven loquat cultivars grown in China were evaluated for their phenolic compounds and antioxidant activity. Eleven phenolic compounds, i.e., 3-p-coumaroylquinincacid (3-p-CoQA), 5-caffeoylquinic acid (5-CQA), 4-caffeoylquinic acid (4-CQA), 3-caffeoylquinic acid (3-CQA), 5-feruloyl...
