制备方法与用途

产品描述

黄曲霉毒素是黄曲霉菌(Aspergillus flavus)及寄生曲霉(A. parasiticus)中产毒菌株的代谢产物,主要包括黄曲霉毒素B1、B2、G1、G2及其衍生物M1、M2、P1、B2a和G2a等。这些化合物结构相似,其中M1和M2是黄曲霉毒素B1和B2的衍生物。据报道,黄曲霉菌主要产生黄曲霉毒素B1和B2,而寄生曲霉则主要产生黄曲霉毒素G1、G2、B1和B2。我国食品的主要污染菌为黄曲霉菌。

黄曲霉毒素主要污染粮、油及其制品,如花生、花生油、玉米、大米、棉子等。除此以外,核桃、杏仁、榛子、高粱、小麦、黄豆及豆类、马铃薯、蛋、乳及乳制品、肝、香肠或鱼干及辣椒等也均有可能受到污染。根据我国大规模普查食品污染的资料来看,南方高温、高湿地区的粮油及其制品易受污染,而华北、东北、西北地区除个别样品外,一般不会受到黄曲霉毒素的污染。

生物活性

Aflatoxin G1 是一种自然界中产生的黄曲霉毒素,由Aspergillus flavus 和 Aspergillus parasiticus 等霉菌产生。这些毒素在饲料、坚果、葡萄酒、香料和其他粮食作物中被发现,并具有致肝、致畸和致癌的特性。

    Biodegradation of aflatoxin B1 with cell-free extracts of Trametes versicolor and Bacillus subtilis
    摘要:
    Aflatoxin B1 (AFB1) is one of the most common contaminants of poultry feed and has been linked to adverse effects on animal health and productivity. In this study, the degradation of AFB1 was studied with cell-free extracts (CFE) of Trametes versicolor and Bacillus subtilis using High-Performance Liquid chromatography (HPLC). CFE from B. subtilis and T. versicolor gave 60% and 34% of AFB1 degradation respectively, while heat-inactivated extracts showed no degradation. By-products obtained at the end of AFB1 degradation were analyzed by Liquid Chromatography with tandem mass spectrometry (LC-MS/MS). After 96 h of incubation, by-products with lower m/z values were obtained with CFE from B. subtilis as compared to that from T. versicolor, indicating a higher degradation efficiency of the former. Additionally, the detection of a by-product which could correspond to AFB1-8,9 dihydrodiol - a less toxic derivative of AFB1 - after 72 and 96 h of incubation with CFE from B. subtilis, could indicate the simultaneous detoxification along with degradation of AFB1 by B. subtilis CFE.

    摘要:
    两种暴露方案用于建立虹鳟鱼中黄曲霉毒素B1(AFB1)和黄曲霉酚(AFL)的体内肝致癌性和DNA加合的完整剂量反应关系。通过被动卵暴露,AFL的吸收率不及AFB1,但更有效地被螯合到胚胎本身中,从而产生与致癌物剂量呈线性关系且DNA结合指数比AFB1大三倍的胚胎DNA结合曲线。两种黄曲霉毒素均产生相同的表型反应,主要是混合性肝细胞/胆管细胞癌。对数[发生率]与[剂量]的肿瘤反应是平行偏移,非线性反应,显示在所有检查剂量下,AFL的致癌效力都高出三倍(即,AFB1的三倍于产生同等肝脏所需的AFL)肿瘤发生率)。通过分子剂量分析(logit [incidence] vs. [DNA adducts]),这两个数据集是重合的,这表明,在体内总胚胎DNA中形成的每个DNA加合物中,这两种黄曲霉毒素在肿瘤起始中同样有效。通过食物油炸暴露,两种致癌物在肝脏中均产生线性的DNA结合剂量反应,但通过该暴露
