作者曾发现向日葵籽中存在着一些萤光物质干扰用一般方法对黄曲霉毒素的测定。因此提出了以下的方法避免这种干扰。在50克通过2毫米筛的向日葵籽粉内,加入25毫升的水,25克酸洗助填剂(Gelite 545)和250毫升氯仿,振荡30分钟,过滤。取滤液50毫升,蒸发至3毫升。柱纯化:在备有玻璃活塞,400×22 The authors have found that some fluorescent substances in sunflower seeds interfere with the determination of aflatoxins by conventional methods. Therefore, the following method is proposed to avoid such interference. To 50 g of sunflower seed powder passing through a 2 mm sieve was added 25 ml of water, 25 g of pickling aid (Gelite 545) and 250 ml of chloroform and shaken for 30 minutes and filtered. Take the filtrate 50 ml, evaporated to 3 ml. Column purification: equipped with glass piston, 400 × 22
