EPA, DHA, cholesterol and phospholipid content were determined in the Trachinus draco, Trigla lyra and (wild and cultured) Pagrus pagrus muscles.The EPA and DHA levels – as determined by GC-GC/MS – in the cultured P. pagrus muscles (233.20 ± 16.3 and 399.39 ± 31.1 mg/100 g of the wet tissue respectively) were found to be significantly higher compared to the ones in the wild P. pagrus, T. draco and T. lyra (26.31 ± 2.26, 158.24 ± 10.92 mg/100 g, 28.65 ± 1.68, 155.97 ± 2.63 mg/100 g 35.66 ± 0.66 and 102.52 ± 1.71 mg/100 g of the wet muscles respectively). The amounts of cholesterol (determined by GC on a capillary column) and phospholipids in the cultured P. pagrus muscles were significantly higher (149.3 mg/100 g and 0.80 g/100 g of the wet tissue respectively) compared to the ones in the wild P. pagrus (8.73 mg/100 g and 0.40 g/100 g), T. draco (41.72 mg/100 g and 0.59 g/100 g) and T. lyra muscles (38.63 mg/100 g and 0.40 g/100 g of the wet tissue respectively).The highest DHA/EPA and ω-3/ω-6 ratios were 6.00 and 5.93 in wild P. pagrus and T. draco muscles respectively, while the lowest in cultured P. pagrus (1.71 and 1.48 respectively). 相似文献

N-benzyloxycarbonyl-protected alpha- or beta-amino alcohols, easily prepared from alpha- and beta-amino acids, were converted into aldehydes and directly reacted with (triphenyl phosphoranylidene) acetonitrile, leading to unsaturated nitriles. Treatment of nitriles with NaN(3) and ZnBr(2) produced unsaturated gamma- and delta-amino tetrazoles, which were deprotected and converted to the corresponding saturated compounds by catalytic hydrogenation. For the case of delta-amino tetrazole, the methylation of the acidic moiety occurred after treatment with CH(2)N(2), leading to the N(1)- and N(2)-methylated constitutional isomers, which were separated by column chromatography and hydrogenated. 相似文献
