Abstract

44,55-Dihydroxyyessotoxin (1) was isolated from extracts of Protoceratium reticulatum and identified by analysis of its one- and two-dimensional NMR and mass spectra. In addition, LC-MS methods revealed the presence of compounds tentatively identified as (44-R,S)-44,55-dihydroxy-41a-homoyessotoxin (2) and (44-R,S)-44,55-dihydroxy-9-methyl-41a-homoyessotoxin (3). LC-MS analyses indicate that 1 is a constituent of P. reticulatum in New Zealand and Norway, and it was present in three species of mussels from New Zealand, Norway, and Canada.

摘要

44,55-二羟基岩沙海葵毒素（1）从网纹原甲藻提取物中分离得到，并通过一维和二维核磁共振光谱以及质谱分析进行鉴定。此外，液相色谱-质谱联用方法揭示了初步鉴定为（44-R,S）-44,55-二羟基-41a-高岩沙海葵毒素（2）和（44-R,S）-44,55-二羟基-9-甲基-41a-高岩沙海葵毒素（3）的化合物的存在。液相色谱-质谱联用分析表明，1是新西兰和挪威网纹原甲藻的一种成分，并且存在于来自新西兰、挪威和加拿大的三种贻贝中。
