“…The liberated fatty acids were obtained by ether extraction and dried over anhydrous Na2SO4. Ethereal diazomethane solution was extracted corresponding methyl esters from the extracted fatty acids (Farag, Ahmed &Ewies, 1986). Gas chromatography (HP 6890 Series) was conducted for fatty acid methyl esters fractionation.…”

Investigation of the primary products showed that the carbohydrates of Echinops spinosissimus, aerial parts were 23.23%, while the detected free and combined sugars were 9 free sugars and 13 combined sugars. The detected values of total nitrogen and total protein were 1.79% and 11.2%, respectively. Amino acid analyzer of total amino acids revealed the presence of 15 amino acids. The detected percentage of total lipid was 3.45%. Meanwhile GLC analysis revealed the presence of 6 saturated fatty acids and 2 unsaturated fatty acids. Further flavonoids of Echinops spinosissimus using HPLC revealed the presence of 22 compounds, with the major compounds Hespirtin (39.233 mg/100g), Hespiridin (34.589 mg/100g), Luteolin-6-arbinose-8-glucose (25.344 mg/100g), Apigenin-6-arbinose -8-glactose (23.049 mg/100g) and Apignin-6-glucose -8-rhamnose (20.083 mg/100g). While on using paper and TLC chromatographers revealed the separation and identification of 5 pure flavonoid compounds (apigenin, kampferol, hespiridin, hespirtin and rutin) and 2 phenolic acids (gallic acid and ferulic acid).Copy Right, IJAR, 2013,.

The natural feeding of 609 Octopus aegina was studied in relation to the environmental seasonal variations in three populations in the Suez Canal, the Gulf of Suez and the Mediterranean Sea. Samples were collected seasonally from March 2009 till May 2010. Analysis of the stomach contents revealed that O. aegina attained the highest percentages of empty stomachs during spring for the three populations. The (1/2) full stomachs was dominant in the collected samples (32.97 %). The study revealed that 34.43 %, 32.83 % and 32.10 % of the examined stomachs were empty in the samples of Suez Canal, Gulf of Suez and Mediterranean, respectively. There was no definite seasonal food preference, and crustaceans were the most preferable food item followed by fishes. The biochemical composition of O. aegina revealed that females are higher than males in total protein content (72.41 % and 69.29 % for immature and mature females respectively) and total lipid content (38.4 g/100 g dry weight and 33.2 g/100 g dry weight for immature and mature females respectively). Amino acid analysis showed that O. aegina contains higher percentage of non essential amino acids (NEAA) than essential amino acids (EAA). Leucine, Lysine and Arginine had the highest percentage of EEA, while Asparagine, Glutamate and Glycine had the highest percentage of NEAA. EAA in males increased from 36.64% to 37.93 % in immature and mature respectively, while in females it increased from 36.93 % to 41.5 % in immature and mature respectively. Fatty acid analysis showed that males O. aegina contain higher percentage content of fatty acid components (SFA and UFA) than females. The results also revealed that SFA tended to decrease by maturation in males and females. Palmitic (16:0) and Stearic (18:0) were the most abundant SFA. Mature males had the highest percentage content of PUFA.
