摘要
在江苏及浙江共5个地点采集了8种贝类,使用四甲基氢氧化胺和9-氯乙基蒽衍生的高效液相色谱法,检测样品的大田软海绵酸含量。结果表明:样品中的大田软海绵酸含量从15.75～218.95ng·g-1,平均含量为37.10ng·g-1,检出率为48%。有一个样品的含量超过食用标准(200ng·g-1)。从该结果与其他研究结果可以推断腹泻性贝类毒素在我国分布区域较广,且在某些地区含量较高。
8 species of shellfish which were collected from Jiangsu and Zhejiang Provinces in Feb. 1992, were detected for okadaic acid by high performance liquid chromatography with 9chloromethylanthracene (9CA) and tetramethylammonium hydroxide (TMAH). The result showed that the range of okadaic acid content is from 15.75～218.95ng·g-1, and the average of content is 37.10ng·g-1. 48% samples were detected okadaic acid, and the content of one sample was beyond the critical limit (200ng·g-1). It suggests that the diarrhetic shellfish poison is widely distributed in China, and shellfish from some areas contain high toxicity.
