| 摘 要： | 麻痹性贝类毒素GTX1/4和GTX2/3是我国近海危害最严重的藻毒素。本研究以染毒紫贻贝为原料，贝肉均质后以0.18 mol/L甲酸溶液超声提取，提取液先用乙酸乙酯和氯仿洗涤，然后用大孔吸附树脂SP700净化，亲水型高效制备液相色谱分离纯化，得到麻痹性贝类毒素GTX1/4和GTX2/3组分，为麻痹性贝类毒素标准物质的研制提供了可靠的技术方法。

| Abstract: | GTX1/4 and GTX2/3 are the most harmful algal toxins in the coastal waters of China. The paralytic shellfish toxins from mussel samples were extracted with 0.18 mol/L formic acid aqueous solution, cleaned up with ethyl acetate and trichloromethane. Then, the crude PSTs solutions were separated by macroporous adsorption resin SP700 and purified by preparative high performance liquid chromatographic (PHPLC) coupled with Hillic column. It developed an effective method for the preparation of paralytic shellfish toxins reference materials. |
