| 摘要: |
| 采用高效液相色谱法测定了2010 年6 月东海海水中的腐胺、精胺、亚精胺、2-苯基乙胺四种游离态多胺。结果表明, 腐胺的浓度最高, 为5.16～62.28 nmol/L, 占总组成的比例为62%±15%; 亚精胺的浓度最低, 为0~6.98 nmol/L, 占总组成的比例为6%±5%。从大面分布看, 四种多胺在长江口和杭州湾附近浓度大都较高; 从断面垂直分布看, 2-苯基乙胺、亚精胺和精胺在大多数断面的中层浓度均高于底层浓度, 腐胺在大多数断面的底层浓度高于表层浓度。夜光藻赤潮爆发处多胺的浓度相对较高。 |

| Abstract: |
| The concentrations of free 2-Phenylethylamine, putrescine, spermidine, and spermine in water samples collected from East China Sea in June 2011 were measured with HPLC. The results showed that the concentration of putrescine was the highest one ranging from 5.16 to 62.28 nmol/L, owning 62%±15% of total free polyamine. The concentration of Spermidine was the lowest ranging from 0 to 6.98 nmol/L, owning 6%±5% of total free polyamine. The concentrations of most polyamines were very high near the entrance of Changjiang River and the Hangzhou Bay. The contents of 2-Phenylethylamine, spermidine, and spermine in middle layer were all higher than those in the bottom layer, and the contents of putrescine in the bottom layer were higher than those in the surface layer. The polyamine concentration were relatively higher at the place where the red tide of Noctiluca scintillans occurred. |
