Agrimonia eupatoria L. and Cynara cardunculus L. Water Infusions: Phenolic Profile and Comparison of Antioxidant Activities

Abstract

Abstract:Reactive oxygen species (ROS) are highly considered in the ethiopathogenesis of different pathological conditions because they may cause significant damage to cells and tissues. In this paper, we focused on potential antioxidant properties of two medical plants such as the Agrimonia eupatoria L. and Cynara cardunculus L. Both plants have previously been studied for their pharmacological activities, especially as hepatoprotective and hypoglycemic activities. It has been suggested, that their effects are related to the antioxidant properties of polyphenols, which are dominant compounds of the plants' extracts. In the present study HPLC-MS analysis of water infusion was performed allowing the identification of several phenolic constituents. Furthermore, antioxidant effects of the two extracts were compared showing higher effects for agrimony extract compared to artichoke. Thus, agrimony was selected for the in vivo study using the skin flap viability model. In conclusion, our results provide evidence that the A. eupatoria extract may be a valuable source of polyphenols to be studied for the future development of supplements useful in the prevention of diseases linked to oxidative stress.

Artichoke Leaf Extract Inhibits AKR1B1 and Reduces NF-κB Activity in Human Leukemic Cells

“…The present work investigated the antioxidant and antiinflammatory properties of artichoke leaf (bract) extract, the phytochemical profile of which has been described previously (Kuczmannová et al, ) (Table ). The effects of this extract were compared with those of the phenolic compounds caffeic acid, quinic acid, and 3‐caffeoyl quinic acid (chlorogenic acid).…”

Preliminary evaluation of quince (Cydonia oblonga Mill.) fruit as extraction source of antioxidant phytoconstituents for nutraceutical and functional food applications

“…Data were expressed as milligrams per kilogram fresh weight. Compounds were identified on the basis of MS fragmentation pathways and by comparison with the literature data related to caffeoylquinic acids, procyanidins and flavonoids …”

“…Compounds were identified on the basis of MS fragmentation pathways and by comparison with the literature data related to caffeoylquinic acids, [34][35][36] procyanidins and flavonoids. [37][38][39][40]…”

Cardoon as a Sustainable Crop for Biomass and Bioactive Compounds Production

“…The numerous pharmacological activities reported in the literature include studies related to hepatoprotective, diuretic, choleretic, antioxidant, anticarcinogenic, anticholestatic, anti‐influenza, antiviral, antimicrobial, antifungal, anti‐HIV, cholesterol biosynthesis inhibition, LDL oxidation, anti‐inflammatory and vasorelaxant activities . The content of bioactive compounds depends on several factors including the edaphoclimatic conditions, genetics, morphological part of the plant, lifecycle stage, and extraction procedures …”
