Free radical scavengers and antioxidants from Lemongrass (Cymbopogon citratus (DC.) Stapf.).
Methanol, MeOH/water extracts, infusion, and decoction of Cymbopogon citratus were assessed for free radical scavenging effects measured by the bleaching of the 1,1-diphenyl-2-picryl-hydrazyl (DPPH)
Free radical scavenging activity and phenolic content in achenes and thalamus from Fragaria chiloensis ssp. chiloensis, F. vesca and F. x ananassa cv. Chandler
The total phenolic, flavonoid and anthocyanin content of achenes (true fruit) and thalamus (receptacle) from the native South American Fragaria chiloensis ssp. chiloensis (f. patagonica and f.
Comparison of phenolic composition and antioxidant properties of two native Chilean and one domestic strawberry genotypes
Abstract The phenolic composition of extracts from the forms chiloensis and patagonica of Fragaria chiloensis were compared with that of the commercial strawberry Fragaria  ×  ananassa cv. Chandler
Bioactive alkyl phenols and embelin from Oxalis erythrorhiza.
TLDR
The benzoquinone embelin and four alkyl phenols were isolated from an Argentinean collection of Oxalis erythrorhiza, used to treat heart complains, a symptomatology related to Chagas' disease which is endemic in the San Juan Province, Argentine.
Biologically active alkaloids and a free radical scavenger from Prosopis species.
The biological activity of extracts from the aerial parts of five Argentinian Prosopis species and the exudate of P. flexuosa were assessed for DNA binding, beta-glucosidase inhibition and free
Preliminary pharmacological studies on Eugenia uniflora leaves: xanthine oxidase inhibitory activity.
TLDR
The known flavonoids quercitrin, quercetin, myricitrin and myricetin were found to be responsible for the xanthine oxidase inhibitory action of the plant extract.
Proximate composition and free radical scavenging activity of edible fruits from the Argentinian Yungas
The proximate composition and free radical scavenging effect of native food plants gathered in the Argentinian Yungas have been assessed. Some 25 samples were collected for proximate analysis and
Involvement of Ethylene in Stress-Induced Expression of the TLC1.1 Retrotransposon from Lycopersicon chilense Dun.1[w]
TLDR
It is suggested that ethylene-dependent signaling is the main signaling pathway involved in the regulation of the expression of the TLC1.1 element from L. chilense, which is induced in response to diverse stress conditions such as wounding, protoplast preparation, and high salt concentrations.
Antioxidant activity and characterization of constituents in copao fruits (Eulychnia acida Phil., Cactaceae) by HPLC–DAD–MS/MSn
TLDR
The compound identification, associated with the antioxidant activity and insignificant cell toxicity, adds relevant information for the possible development of this native fruit into a new crop.
Synthesis and Antitumor Evaluation of 6-Aryl-substituted benzo[j]phenanthridine- and Benzo[g]pyrimido[4,5-c]isoquinolinequinones
TLDR
Structural–activity relationships within the series of angular quinones reveal that the insertion of pyrrol-2-yl and furan- 2-yl groups at the 6-position is more significant for the increase of the potency and selectivity index of the pharmacophores.
