采用高效液相色谱-电感耦合等离子体质谱法（HPLC-ICP-MS）对7种淡水鱼的水溶性砷化合物组分进行分析。低砷含量被认为是水母的特征。砷甜菜碱（Arsenobetaine，AB）是海蜇组织及部分海蜇粘液中的主要砷化合物。尽管捕食米迦拟胡瓜的胡瓜树的砷含量是B的13倍多。在砷的分布模式上，两种植物的色谱图相似。包括前文所述的两个种在内的9个种的白鲳可分为富砷胆碱和贫砷胆碱两类。海蜇属于Semaostamae被归类为AC丰富的物种。(C)2001爱思唯尔科技有限公司版权所有。
Water-soluble arsenic compound fractions were extracted from seven species of jellyfishes and subjected to analysis by high-performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLC-ICP-MS) for arsenicals. A low content of arsenic was found to be the characteristic of jellyfish. Arsenobetaine (AB) was the major arsenic compound without exception in the tissues of the jellyfish species and mucus-blobs collected from some of them. Although the arsenic content in Beroe cucumis, which preys on Bolinopsis mikado, was more than 13 times that in B. mikado, the chromatograms of these two species were similar in the distribution pattern of arsenicals. The nine species of jellyfishes including two species treated in the previous paper can be classified into arsenocholine (AC)-rich and AC-poor species. Jellyfishes belonging to Semaostamae were classified as AC-rich species. (C) 2001 Elsevier Science Ltd. All rights reserved.
