| BACKGROUND: Unstable generation of free radicals in the body are responsible for many degenerative diseases. A bloom forming algae Euglena tuba growing abundantly in the aquatic habitats of Cachar district in the state of Assam in North-East India was analysed for its phytochemical contents, antioxidant activity as well as free radical scavenging potentials. RESULTS: Based on the ability of the extract in ABTS+ radical cation inhibition and Fe3+ reducing power, the obtained results revealed the prominent antioxidant activity of the algae, with high correlation coefficient of its TEAC values to the respective phenolic and flavonoid contents. The extract had shown its scavenging activity for different free radicals and 41.89 ± 0.41... |

| In 2010, we were determining the contents of glucosinolates in different Brassicas in order to study their influence on feeding of cabbage stink bugs (Eurydema spp.) and the consequent extent of damage. We confirmed that glucosinolates content depends on plant species, plant organs and the time of sampling. In the samples aliphatic glucosinolates (glucoiberin, progoitrin, epiprogoitrin, epiprogoitrin, sinigrin, gluconapin, glucoraphenin, sinalbin) prevailed. Glucobrassicin, an important indolic glucosinolate compound, was detected in all tested Brassicas. Its concentration in the oil radish samples was highest during the first assessment (30 DAS), 8.84 ± 0.65 µmol g-1 ds, while the oilseed rape samples displayed lowest concentration during the last... |

| ABSTRACT This study aimed to prepare jellies of conventional type of red strawberry guava (with added sucrose) and no added sugar and evaluate the physical and chemical composition and content of bioactive compounds in them. Four jellies formulations were prepared: conventional with addition of sucrose (F1), aspartame (F2), saccharin and cyclamate (F3), acesulfame and sucralose (F4). Physicochemical analysis of pH were carried out, as well as analysis of titratable acidity, total soluble solids, ashes, proteins, lipids, moisture, carbohydrates, calories, lightness, color tone, total phenols, anthocyanins, carotenoids, ascorbic acid and antioxidant activity, by the capture of DPPH and ABTS radicals. Conventional and no added sugars jellies did not differ... |

| Abstract Most olive varieties are grown in Jordan using Baladi, Nabali, Crosodi and k18 table olives. This study evaluated the effect of de-bittering fermentation methods on the total phenolic, flavonoid contents, and antioxidants. The phytochemical results of fresh and fermented table olives showed significant decrease after fermentation process and during three months of storage. Baladi fresh table olive presented the highest phenol content (350.9mg GAE/100g) followed by Nabali, Crosodi and k18 varieties, respectively. The highest antioxidant value was found in Baladi variety (42.2%) followed by k18, Crosodi and Nabali varieties, respectively. Crosodi fresh table olive presented the highest flavonoid content (107.4 mg CE/100G), followed by k18, Nabali... |

| ABSTRACT: Osmotic dehydration (OD) is a conservation technique applied to foodstuffs, which promotes partial reduction of water, extends their shelf life and reduces both post-harvest losses and changes in product characteristics. Currently, it has been given emphasis on trying to understand how the process affects the quality of processed vegetables, because process variables can interfere in their antioxidant capacity, color and texture. Moreover, the antioxidant capacity can be affected by chemical changes, leaching losses, reduced moisture and solid gain as well as the present bioactive in the profile of the performed analysis method. In color, the overall changes are caused by temperature increase, which can cause enzymatic and/or non-enzymatic... |

| ABSTRACT: In the current study phytochemical analysis and in vitro antifungal potential of fruits, leaves and stem of Lantana camara L. were studied. The phytochemical analysis indicated the presence of alkaloids, flavonoids, tannins, saponins, glycosides and terpenoids in fruit, stem and leaves of L. camara. The in vitro antifungal activity of fruit, stem and leaves of L. camara was tested against Colletotrichum gloeosporioides Penz. Different concentrations (1-5%) of methanolic extract of all the selected parts of L. camara were applied in vitro against the test fungus. The results of in vitro experiment revealed that higher concentration of methanolic fruit extract (5%) significantly reduced the biomass C. gloeosporioides up to 66%. This effective... |

| This study focused on maximizing the extraction of total phenolics and flavonoids as well as the antioxidant activity measured by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay from roasted yerba mate (Ilex paraguariensis) as a function of time (5, 7.5 and 10 min) and temperature of extraction (60, 75 and 90°C). The data were subjected to Response Surface Methodology and the results showed that polynomial equations were significant, did not present lack of fit, and presented adjusted determination coefficients above 98%, proving their suitability for prediction purposes. Using the desirability function, the optimum operating conditions to obtain a higher extraction of antioxidants was found to be 10 min of extraction at 90°C, and the tea prepared under... |

| BACKGROUND: Turkey is the main apricot producer in the world and apricots have been produced under both dry and irrigated conditions in the country. In this study, phenolic compounds and vitamins in fruits of one wild (Zerdali) and three main apricot cultivars ('Cataloglu', 'Hacihaliloglu' and 'Kabaasi') grown in both dry and irrigated conditions in Malatya provinces in Turkey were investigated. RESULTS: The findings indicated that higher content of phenolic compounds and vitamins was found in apricot fruits grown in irrigated conditions. Among the cultivars, 'Cataloglu' had the highest rutin contents both in irrigated and dry farming conditions as 2855 µg in irrigated and 6952 µg per 100 g dried weight base in dry conditions and the highest chlorogenic... |
