An NMR-based metabolomic approach has been applied to analyse seven aromatic Mediterranean plant species used in traditional cuisine. Based on the ethnobotanical use of these plants, the approach has been employed in order to study the metabolic changes during different seasons. Primary and secondary metabolites have been detected and quantified. Flavonoids (apigenin, quercetin, and kaempferol ...

The protective effects of a series of phenolic compounds, phenolic acids and flavonoids on the cytotoxicity of CCl4 in rat hepatocytes were studied. A number of flavones, 7,8-dihydroxy-flavone, luteolin and hypolaetin-8-glucoside, flavonols, morin, quercetin, robinetin and gossypin, phenolic acids, gallic, caffeic and chlorogenic acids, as well as the flavane (+)-catechin significantly inhibite...

Natural and synthetic xanthone derivatives are well-known for their ability to act as antioxidants and/or enzyme inhibitors. This paper aims to present a successful synthetic methodology towards xanthenedione derivatives and the study of their aromatization to xanthones. Additionally their ability to reduce Fe(III), to scavenge DPPH radicals and to inhibit AChE was evaluated. The results demons...

Byrsonima basiloba A. Juss. species is a native arboreal type from the Brazilian "cerrado" (tropical American savanna), and the local population uses it to treat diseases, such as diarrhea and gastric ulcer. It belongs to the Malpighiaceae family, and it is commonly known as "murici." Considering the popular use of B. basiloba derivatives and the lack of pharmacological potential studies regard...

Objective: Microbial transformations are green biotechnological processes where different microorganisms, or their enzymes used to produce new metabolites from defined substrates. Hesperidin, quercetin, and derivatives have been proven in scientific research a variety of biological activities such as antioxidant, antimicrobial, anticancer activities. 
 Material Method: transformation hespe...

This study revealed polyphenolic content, nutritive content, antioxidant activity, and phenolic profile of methanol and aqueous extracts of Punica granatum peel extract. For this, extracts were screened for possible antioxidant activities by free radical scavenging activity (DPPH), hydrogen peroxide scavenging activity and ferric-reducing antioxidant power (FRAP) assays. The total phenolics and...
