棉籽油内游离棉酚含量测定的方法很多,但多有不足之处。就以首选苯胺光度法为例,它不仅试剂稳定性差,毒性大,且乙醇耗量多,灵敏度又欠佳。故寻找一种简便、快速、灵敏、选择性良好的测试方法就显得很为必要。余忠谊等在 Storhew 等间苯三酚光度法的基础上,改进原方法的酸度与萃取液,测定棉籽仁内游离棉酚含量,取得较好效果。我们用该法基本原理,测定棉籽油
There are many ways to determine free gossypol content in cottonseed oil, but there are some shortcomings. Take the preferred aniline photometric method as an example, it not only poor reagent stability, toxicity, and ethanol consumption, sensitivity and poor. So looking for a simple, fast, sensitive and highly selective test method is very necessary. Yu Zhongyi and other Storhew other phloroglucinol spectrophotometry based on the original method to improve the acidity and extract, determination of cottonseed kernel free gossypol content, and achieved good results. We use the basic principles of this method, determination of cottonseed oil
