| الوصف: | Summary The effects of vitamin enrichment on ascorbic acid (AA) levels in Artemia urmiana were studied by applying an emulsion containing ascorbyl palmitate (AP) as a vitamin C source. Nauplii were kept at 28� C in incubators containing the enrichment medium (cod liver oil, AP, sodium polysurbate, a-tocopherol and tap water) for 0, 12, 18 and 24 h and then starved at 5� C for 0, 12, 18 and 24 h. AA was determined using a reversed phase high performance liquid chromatography coupled to an electrochemical detector. The results showed that nauplii of A. urmiana had high levels of ascorbic acid in their body tissues (1534 ± 166 l gg )1 dry weight) and that the AA concentration increased following enrichment. The maximum enrichment level was reached by hour 18, declining by hour 24. There was a significant difference in AA levels between enriched and non-enriched artemia (P < 0.05). Although AA contents were enhanced in all groups during starvation in cold conditions, the increases were not considerable. However, a clear correlation could be observed between duration of starving and rise in AA levels in non-enriched and 12 and 18 h enriched groups. |
