英文摘要Me optimal conditions were established for the extraction of paralytic shellfish poisoning toxins from gonad of Chlamys nobills using acetic acid and hydrochloric acid in the concentration range of 0.04-1.0 mol/L. A 10-g portion of gonad of Chlamys nobilis was extracted by boiling for 5 min with 1.0 mL acetic acid and hydrochloric acid in a 50-mL beaker. Meanwhile, a portion of gonad of Chlamys nobilis was extracted by sonication in the solution of 0.3 mol/L HAc + 0.2 mol/L HCl for a total period of 5-30 min. The raw extract was centrifuged at 3500 r/min for 5 min and the pH of supernatant was adjusted from 2.0 to 4.0 by 0.1 mol/L NaOH or 5 mol/L HCL After passing through a Millipore ultrafiltration membrane (10000 MW cut-off), ultrafiltrate was then analyzed by HPLC. The results showed that hydrochloric acid in the concentration range of 0.25-1.0 mol/L caused a significant decrease of N-sulfocarbarnoyl-11-hydroxysulfate toxin C1 (C1), C2 and gonyautoxin 5 (GTX5) and the concomitant increase of GTX2,3. However, the amount of the three unstable toxins did not show any change using the extraction with acetic acid. Under the same concentration of acetic acid (0.3 mol/L) and hydrochloric acid (0.2 mol/L), the amount of C1 in the ultrasonic extraction was obviously lower than the boiling one, while C2 showed slightly higher than the latter.; Me optimal conditions were established for the extraction of paralytic shellfish poisoning toxins from gonad of Chlamys nobills using acetic acid and hydrochloric acid in the concentration range of 0.04-1.0 mol/L.
