| 摘 要： | 建立了贝类组织中11种麻痹性贝类毒素的高效液相色谱-串联质谱分析方法,包括STX、dcSTX、NEO、dcNEO、GTX1-4、dcGTX2,3和GTX5(B1)。贝类样品经含0.1%甲酸的80%(体积分数)乙腈水溶液超声提取后,经过冷冻分层,下层固体融化后通过HLB固相萃取小柱富集净化和10 000MWCO(Molecular Weight Cutoff)超滤管超滤截留,超滤液用于仪器分析。采用Zwitterionic亲水性相互作用色谱柱(250 mm×4.6 mm,5 μm,德国)分离,在多反应监测模式下进行定性和定量分析。各组分在一定的范围内具有良好的线性关系,平均回收率大于60%,相对标准偏差小于20%(n=7)。用该方法分析染毒的栉孔扇贝样品,证实了对PSP毒素具有良好的分析测定效果。
