摘　　要：利用高效液相色谱法测定了2011年东海赤潮演替过程中海水中的主要的游离态多胺腐胺、亚精胺和精胺的浓度.调查海区腐胺、亚精胺和精胺的浓度范围分别为0~48nmol/L,3~11nmol/L和2~17nmol/L,其中腐胺的平均浓度最高,亚精胺次之,精胺的浓度最低.从平面分布看,在4月份以中肋骨条藻为主的硅藻赤潮爆发期,和5月份以东海原甲藻为主的甲藻赤潮爆发期,赤潮爆发的区域多胺浓度相对较高;各个断面的多胺浓度随着赤潮爆发的过程发生变化,并且与DOC、POC、DON以及C/N等呈较明显的相关性.The predominant polyamines（spermine, putrescine and spermidine） of seawater in the area of frequent red-tide occurrence of the East China Sea in spring 2011 were measured by HPLC. The results showed that putrescine, spermidine and spermine in the survey area ranged between 0~48, 3~11 and 2~17nmol/L respectively. The average concentration of putrescine was the highest, followed by spermidine and spermine. During diatom bloom that dominated by Skeletonema costatum and dinoflagellate bloom that dominated by Prorocentrum donghaiense occurring, polyamine concentration was relatively higher in area where algae bloom broke out. Polyamine concentration varied with process of algae bloom outbreak, and showed correlation with DOC, POC, DON and C/N.
