山稔子提取物对油脂抗氧化作用的研究

Antioxidation of Extracts from Fructus rhodomyrti on Peanut Oil and Lard

本实验以山稔子为原料,研究了山稔子提取物对油脂的抗氧化作用。实验表明,山稔子的水、无水乙醇、甲醇、50%甲醇、正己烷和乙酸乙酯的提取物对猪油和花生油均具有抗氧化作用,而且其抗氧化作用的强弱与溶剂的极性直接相关。经过分析比较发现,50%甲醇和水的提取物对猪油和花生油的抗氧化效果较好,而50%甲醇稍占优。

Antioxidation of extract from Fructus rhodomyrti on oil was studied in this study. The results showed that the extracts from Fructus rhodomyrti by water, alcohol, methanol, 50% methanol, n-hexane and acetic ester have antioxidation on lard and peanut oil. In comparison, it was found that the effects of antioxidation of 50% methanol and water extracts are better, and the 50 % methanol extract is the superior one.
