摘要
根据Oshima建立的高效液相色谱法 (HPLC)对广东大亚湾不同时期的华贵栉孔扇贝 (Chalmysnobilis)和翡翠贻贝 (Pernaviridis)消化腺所含的麻痹性贝类毒素 (PSP)进行了分析。结果显示 ,两种贝类消化腺所含的PSP成分基本相同 ,主要成分为低毒力的N -磺酸氨基甲酰类毒素GTX5、C1和C2 及高毒力的氨基甲酸脂类毒素GTX1 4 ,而STX和neoSTX通常不足总量的 5 %。与扇贝相比 ,贻贝消化腺的PSP在数量和毒力上均低于前者。通过比较藻毒与贝毒成分 ,推测贝类的毒素来源于塔玛亚历山大藻香港株AlexandriumtamarenseATHK。
The paralytic shellfish poisoning(PSP) profiles of digest gland extraction samples from scallop Chalmys nobilis and mussel Perna viridis collected at two stations in Daya Bay, Guangdong from March to June 1998 have been analyzed by HPLC established by Oshima. The results showed that a similar suite of toxins presents in each sample and the low potency N-sulfocarbamoyl toxins (GTX 5, C 1 and C 2) and the high potency gonyautoxins GTX [1-4] had a high proportion, and the saxitoxin derivatives were less than 5% of total toxin content. The dominant toxin was GTX 5 up to 25% for scallop and 13% for mussel. In the molluscs, GTX 1 and GTX 2 dominated over their epimers GTX 4 and GTX 3, respectively. Either toxicity or toxin content in scallop is higher than in mussel. The similar toxins indicates that the HK strain of Alexandrirm tamarense , which was found and isolated from the same bay, was possible the paralytic shellfish poisoning-producing causative ouganism.
