| 摘 要： | 为了探究鱼类不同组织中矿物元素的含量，实验以养殖黄颡鱼为对象，采用电感耦合等离子体质谱法测定了黄颡鱼18个组织(心脏、肝脏、脑、脾脏、肾脏、肌肉、脂肪、前肠、中后肠、眼睛、鳃、尾鳍、鱼鳔、骨骼、胃、皮肤、血液、全鱼)中7种矿物元素(Ca、Mg、Zn、Fe、Cu、Mn和Se)的含量与分布。结果显示，Ca在骨骼、鳃、尾鳍和肌肉中占比较高，在尾鳍和骨骼中含量最高，在脂肪组织中含量最低；Mg在骨骼和肌肉中占比较高，在骨骼和尾鳍中含量最高，在眼睛中含量最低；Zn在骨骼、肌肉、皮肤和眼睛中占比较高，在眼睛中含量最高，在脂肪组织中含量最低；Fe在骨骼、血液和肌肉中占比较高，在血液中含量最高，在脂肪组织中含量最低；Cu在骨骼、肌肉和肝脏中占比较高，在肾脏和肝脏中含量较高，而在脂肪和眼睛中含量最低；Mn在骨骼和肌肉中占比较高，在骨骼和尾鳍中含量较高，在眼睛和脂肪中含量较低；Se在肌肉、骨骼、皮肤和肝脏中占比较高，在脾脏、肝脏、肾脏和前肠中含量较高，在肌肉和脂肪中含量较低。研究表明，黄颡鱼体内含有丰富的矿物元素(Ca、Mg、Zn、Fe、Cu、Mn、Se)，而且在不同组织中具有不同的分布特征。研究采用ICP...

| Abstract: | Yellow catfish (Pelteobagrus fulvidraco) has good taste and nutritional value, and can provide the necessary mineral elements for the human body. In order to explore the content of mineral elements in different tissues, the experiment use the P. fulvidraco as the object. The distribution and content of calcium (Ca), magnesium (Mg), zinc (Zn), iron (Fe), copper (Cu), manganese (Mn) and selenium (Se) were determined by flame atomic absorption spectrometry in 18 tissues of P. fulvidraco (heart, liver, brain, spleen, kidney, muscle, fat, fore-intestine, mid-intestine, eyes, gill, tail fin, swim bladder, bone, stomach, skin, blood and whole fish). The results showed that Ca accounted for a higher proportion in bone, gill, tail fin and muscle, and the Ca content was the highest in tail fin and bone and the lowest in fat; Mg accounted for a higher proportion in bone and muscle, and the Mg content was highest in bone and tail fin and the lowest in eyes; Zn had a higher proportion in the bone, muscle, skin and eye, and the Zn content was the highest in eyes and the lowest in fat tissue; Fe had a higher proportion in the bone, blood and muscle, and the Fe content was the highest in blood and the lowest in fat; Cu had a higher proportion in bone, muscle and liver, and the Cu content was the highest in kidney and liver, while the lowest in fat and eyes; Mn had a higher proportion in bone and muscle, and the Mn content was the highest in bone and tail fin and the lowest in eyes and fat; Se had a higher proportion in muscle, bone, skin, and liver, and the Se content was highest in spleen, liver, kidney, and fore-intestine, and the lowest in muscle and fat; The present study used ICP-MS to explore the distribution and content of mineral elements (Ca, Mg, Zn, Fe, Cu, Mn and Se) in different tissues of P. fulvidraco, which provided good basis for determining the nutritional value of mineral elements in P. fulvidraco, and also has important significance for related research of mineral elements in other fishes. |
