Main chemical composition, bioactive constituents and antioxidant activity of Egyptian lupine and fenugreek seeds were investigated. The obtained resultsshowed that white lupine seeds have higher amount of carbohydrate and ash than that in the other seeds. Meanwhile yellow lupine seeds showed the highest percentage of fibers among all tested seeds, while fenugreek seeds were characterized by large amount of crude protein, oil and moisture comparing with both kinds of lupine seeds. On the other side, analysis of bioactive constituents revealed the presence of total phenolics, total flavonoids as well as saponins in the highest amount in fenugreek seeds, whereas the highest values of alkaloids and tannins were belonged to yellow lupine. It is noteworthy that white lupine exhibited the lowest amounts of all tested bioactive components among all studied seeds.And finally, in vitro antioxidant activity using two deferent methods, showed a correlation between total phenolics and total flavonoids on one hand and antioxidant activity on the other hand, where it showed the highest values for fenugreek seeds followed by yellow and white lupine seeds respectively.

The present research determined the chemical composition and the antioxidant activity of leaves extracts (aqueousacetone) of Moringa oleifera variety grown in Egypt. It was found that moringa leaves contain total ash 8.03%, crude lipids 3.14%, crude protein 26.31%, total carbohydrates 44.89%, and crude fiber 17.63%. Total phenolics in leaves aqueous extract were 243.8 mg/g and total flavonoids were 145.22 mg/g, while in acetone extract total phenolics were 142.51 mg/g and total flavonoids were 124.64 mg/g. HPLC results showed that moringa leaves contained 23 phenolic compounds and 22 flavonoid contents and the main constituents of both were Pyrogallol, Salycilic, Catechin, Ellagic, Alphacoumaric, 3,4, Protocatechuic and Chlorogenic) and Hesperidin and Rosmarinic) respectively. In comparison with the acetone extract, the aqueous extract showed the highest activity in reducing power assay. Egyptian moringa leaves extracts were found to have antioxidant activity due to their high amount of total phenolics and falvonoids.

This study was carried out to investigate the following objectives, studying the heavy metals (Arsenic, Lead , Cadmium and Mercury) in fresh water which lived it fishes under investigation such as River Nile, lakes and farmed fish at different areas in Egypt and fillet fishes under investigation. Studying the chemical compositions of tilapia, catfish and common carp fishes. Determination of fat soluble vitamin in fishes. Determination of some physicochemical properties of oil fishes. Evaluation the some antioxidant, hypolipidemic, and liver function on rats fed on diet supported with oil of the fishes under investigation compared with standard diet.

The changes of biochemical compositions of arabica coffee beans were determined before and after roasting and storage. The caffeine content increased due to storage coffee beans under atmospheric air or nitrogen gas. The roasting of beans at 180°C for 15, 20 and 30 min to produce light, medium and dark coffee increased caffeine content in all samples. It was found that trigonelline content decreased as a result of both roasting and storage. The effect of roasting and storage of coffee beans for 3 and 6 months revealed a presence of new fatty acids as a degradable product. The beans stored under air or nitrogen, short chain fatty acids were appeared and linoleic was decreased, while palmitic and stearic were increased. The remarkable changes in the fatty acid composition showed especially when stored under atmospheric air, mean while storage under nitrogen resulted in less degradation in the unsaturated fatty acids.

Cichorium intybus and Portulaca oleracea plants native to the northAfrica, especially in Egypt have been chosen for such study due to their importance both as food and as medical plants for treating several common diseases. The present study analyzes chemical and phytochemical constituentes of Portulaca oleracea and Cichorium intybus and evaluates their therapeutic roles on liver, kidney functions and complete blood count in H2O2 intoxicated rats. Six groups of experimental animals are fed on basal diet, five of them intoxicated with H2O2 in drinking water then treated with Portulaca oleracea and Cichorium intybus extracts. This study shows that the total phenolics and total flavonoids contents in Cichorium intybus extracts are higher than that in the Portulaca oleracea extracts. Cichorium intybus extract at orally dose of 75 mg/kg bw improve liver, kidney functions and normalize hematological parameters. It also decreases the MDA level, increases SOD and CAT activities. Cichorium intybus has hepatorenal protective effect as it can protect tissue from free radicals and may provide a cushion for a prolonged therapeutic option against liver and kidney diseases without harmful side effects.
