Effect of chromium on the fatty acid composition of two strains of Euglena gracilis.
The results indicate that hexavalent chromium affects levels of fatty acids, especially those related to photosynthetic activity, especiallythose related to chloroplast structures.
Fatty acids, sterols and other steroids from seeds of Patagonian Prosopis species
The seed lipids contained a relatively large proportion of unsaturated fatty acids, with linoleic and oleic acids being predominant and β-Sitosterol was the major steroid in all species studied.
Chromium induced stress conditions in heterotrophic and auxotrophic strains of Euglena gracilis.
Tolerance of MAT strain against Cr(VI) stress is not only related to GSH level and/or biosynthesis capacity but is also related to the participation of the SOD antioxidant enzyme.
Preparation and antitrypanosomal activity of secochiliolide acid derivatives.
The results indicate that the carboxyl group is not essential for the bioactivity of 1, while the presence of the tetrasubstituted exocyclic double bond seems to be important.
Effect of secochiliolide acid isolated from the Patagonian shrub Nardophyllum bryoides as active component in antifouling paints
The performance of secochiliolide acid, the main component isolated from Nardophyllum bryoides ethanolic extract, was evaluated for inclusion in rosin-based coatings and highlighted the importance of terrestrial plants as a sustainable source of potential environmentally friendly antifoulant candidates.
Lipid Fraction from Industrial Crustacean Waste and Its Potential as a Supplement for the Feed Industry: A Case Study in Argentine Patagonia
In central Patagonia, the most important crustaceans caught are the Argentine red shrimp (ARS) (Pleoticus muelleri) and the southern king crab (SKC) (Lithodes santolla). Their industrial processing
Cytotoxic terpenoids from Nardophyllum bryoides.
The investigation of the ethanol extract of fresh aerial parts of the Patagonian shrub Nardophyllum bryoides collected in the province of Chubut, Argentina, yielded eleven terpenoids, four of which are hitherto unknown and several showed moderate cytotoxicity against a human pancreatic adenocarcinoma cell line.
Evaluation of the Biological Activities of Crude Extracts from Patagonian Prosopis Seeds and Some of Their Active Principles
Fatty acids and a group of pentacyclic triterpenes were identified as responsible for antibacterial activities in some of the active extracts.
Variation in the proximate composition and fatty acid profile recovered from Argentine hake ( Merluccius hubbsi ) waste from Patagonia
The extraction of marine fish oil and the production of fish offal meal from waste from fish factories would contribute to the sustainability of the regional industry, because it would also decrease the volume of waste, with benefits to the environment.
Chemical Composition and Bioactivity of Acantholippia seriphioides Essential Oils from Patagonia
Abstract The aerial parts of Acantholippia seriphioides (A. Gray) Mold. were collected from three sites in the neighborhood of Comodoro Rivadavia, in Patagonia (Astra, Saavedra and Rada Tilly), and
