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)
Inhibitory Effect of Three C-glycosylflavonoids from Cymbopogon citratus (Lemongrass) on Human Low Density Lipoprotein Oxidation
It is demonstrated that isoorientin (1) is an effective inhibitor of in vitro LDL oxidation, a key event in the formation of atherosclerotic lesions, and the use of this natural antioxidant may be beneficial to prevent or attenuate atherosclerosis.
Anti-Proliferative Activity of Meroditerpenoids Isolated from the Brown Alga Stypopodium flabelliforme against Several Cancer Cell Lines
Six meroditerpenoids isolated from the brown alga Stypopodium flabelliforme showed good activity against all cell lines, with SH-SY5Y and RAW.267 being the most susceptible to antimicrobial activity.
Free Radical Scavenging Activity and Secondary Metabolites from in vitro Cultures of Sanicula graveolens
An in vitro propagation system was developed to obtain shoot and root cultures from the Andean spice Sanicula graveolens (Apiaceae). Propagation of shoots, roots and plantlets was achieved by the
Free Radical Scavengers from Cymbopogon citratus (DC.) Stapf Plants Cultivated in Bioreactors by the Temporary Immersion (TIS) Principle
The biomass production of Cymbopogon citratus shoots cultivated in bioreactors according to the temporary immersion (TIS) principle was assessed under different growth conditions and the free radical scavenging effect of the methanolic extract and compounds was measured.
E-cinnamic acid derivatives and phenolics from Chilean strawberry fruits, Fragaria chiloensis ssp. chiloensis.
HPLC analyses of extracts showed that cyanidin-3-O-beta-D-glucopyranoside and free ellagic acid are present in achenes while the E-cinnamoyl derivatives and tryptophan were identified only in the thalamus and the free radical scavenging effect of the fruit extract can be associated with the anthocyanin content.
Epilobium angustifolium extract demonstrates multiple effects on dermal fibroblasts in vitro and skin photo-protection in vivo.
The results collectively suggest that Epilobium angustifolium extract may possess anti-aging properties and that the EA polyphenols might account for these benefits.
Separation of Aeruginosin-865 from Cultivated Soil Cyanobacterium (Nostoc sp.) by Centrifugal Partition Chromatography combined with Gel Permeation Chromatography
Aeruginosin-865 was isolated from cultivated soil cyanobacteria using a combination of centrifugal partition chromatography (CPC) and gel permeation chromatography to confirm its chemical identity by comparing its spectroscopic data with those of an authentic standard and data available in the literature.
