【摘要】 从一份抗氧化性样品中分离出三个组分（Ⅰ、Ⅱ和Ⅲ）。组分Ⅰ经元素分析和ＩＲ光谱鉴定证明是双苯胺棉酚，这个鉴定结果和先前的１ＨＮＭＲ鉴定结果是一致的。组分Ⅱ通过元素分析、质谱和ＩＲ光谱鉴定证明是三聚氰胺。组分Ⅲ，ＩＲ光谱鉴定证明是次磷酸二氢纳。分离过程的平均回收率为（９７．２±３．２）％．更多还原

【Abstract】 Three components were separated by a suitable method from an antioxygenic sample. The identifications of IR Spectra etc. prove that the above mentioned components are dianiline gossypol, melamine and sodium hypophosphite, respectively. The average recovery of the unknown sample are (97.2±3.2)%.更多还原
