| 摘 要： | 目的从两株微小亚历山大藻(Alexandrium minutum Halim)中分离纯化膝沟藻毒素(Gonyautoxins).方法用胶滤层析、离子交换层析等方法从人工培养的两株微小亚历山大藻酸酒精萃取物中分离纯化膝沟藻毒素,再用HPLC法对毒素进行定性定量测定.结果从两株藻株培养液中均分离得到膝沟藻毒素GTX-4,GTX-1,GTX-3,GTX-2,其中Amtk4藻株的毒素含量为Amtk2的近10倍.结论微小亚历山大藻Amtk4藻株适于制备膝沟藻毒素.

| Abstract: | Aim To study isolation and purification of Gonyautoxins from two different strains of Alexandrium minutum Halim. Methods Ethanol extracts of the two culture strains of Alexandrium minutum Halim were fractionated by gel filtration and ion exchange chromatography to obtain gonyautoxins. The toxin profiles were tested by HPLC method. Results Both strains contain gonyautoxin-1, gonyautoxin-2, gonyautoxin-3 and gonyautoxin-4. The total gonyautoxin content of Amtk4 strain is almost 10 times higher than that of Amtk2 strain. Conclusion Alexandrium minutum Halim Amtk4 strain is suitable for the preparation of Gonyautoxins. |
