摘要
应用油脂抗氧化活性导向,采用聚酰胺、硅胶等柱色谱从黄荆子提取物中分离得到两个化合物,经波谱分析结构鉴定为异嗪皮啶(Ⅰ)和3,4-二氢-6-羟基-4-(4-羟基-3-甲氧基苯基)-3-羟甲基-7-甲氧基-2-醛基萘(Ⅱ)。添加质量分数0.04%的异嗪皮啶(Ⅰ)在猪油中的抗氧化效果以及添加质量分数0.06%的3,4-二氢-6-羟基-4-(4-羟基-3-甲氧基苯基)-3-羟甲基-7-甲氧基-2-醛基萘(Ⅱ)在猪油中的抗氧化效果均比添加质量分数0.02%的2,6-二叔丁基-4-甲基苯酚(BHT)强,而且具有量效关系。
With a view to guide-antioxidant activity for oil,two compounds were isolated from Vitex negundo L.seeds by polyamide and silica gel chromatographic methods,and identified to be isofraxidin(Ⅰ) and 6-hydroxy-4-(4-hydroxy-3-methoxyphenyl)-3-hydroxymethyl-7-methoxy-3,4-dihydro-2-naphthaldehyde(Ⅱ) respectively by spectroscopic method.The antioxidant effect of both w(Ⅰ)=0.04% and w(Ⅱ)=0.06% was better than that of w(BHT)=0.02% in lard,and the effect increased with increasing concentration.
