Abstract: A rapid method has been proposed for determination of the main conjugated linoleic acid precursors such as linoleic (C18:2 n-6) and linolenic (C18:3 n-3) acids in forages by capillary zone electrophoresis (CZE) with direct UV detection at 200 nm. Among the fatty acids found in forages, C18:2 n-6 and C18:3 n-3 have received particular attention due to their roles as precursors for the synthesis of conjugated linoleic acid, a class of health-enhancing compounds that is predominantly found in dairy products. The electrolyte background consisted of 12.0 mmol/L tetraborate buffer (pH 9.2) added to 12.0 mmol/L Brij 35(®), 17% acetonitrile, and 33% methanol. Under the optimized conditions, the baseline separation of C18:2 n-6 and C18:3 n-3 was achieved within 4 min. The CZE-UV method was compared to GC with a flame ionization detector, which is the American Oil Chemists' Society (AOCS 996.06) official method for fatty acid analysis. The methods did not show any evidence of significant differences within 95% confidence interval (P > 0.05). The CZE-UV method was successfully applied to the analysis of 80 genotypes of Brachiaria ruzizienses clones submitted to a genetic improvement program in agricultural research. |

The knowledge on nutrient cycling through litter is important for the management of the species in agroforestry systems (SAFs), since the litter is an important way of making plant nutrients available to soil. The aim of this work was to evaluate the litterfall production and nutrient cycling of woody species in an agroforestry system of Caatinga. The study was developed in SAF belonging to Embrapa Goats and Sheep, located in the county of Sobral-CE, Brazil. The evaluated species were four native leguminous from Caatinga: Mimosa caesalpiniifolia (sabiá), Mimosa tenuiflora (jurema-preta), Libidibia férrea (jucá) and Poncianella piramydalis (catingueira). To collect the litter, collectors were installed under the tree canopy, using six replicates for each species evaluated. |
