蓝莓果渣中总黄酮的提取纯化及抗氧化性能的研究

Extraction and antioxidation of total flavonoids from the marc of blueberry

研究了从废弃的蓝莓果渣中提取纯化总黄酮的工艺,采用紫外分光光度法测定其含量,并对其抗氧化作用进行了初步研究。实验结果表明:利用HPD-600大孔树脂纯化蓝莓果渣黄酮可使其纯度提高4.8倍,且该方法的精密度、准确性、精密度良好,加样回收率达100.6%。同时实验还得出,蓝莓果渣黄酮的抗氧化性明显。

The technologies of total flavonoids extraction from the marc of blueberry were studied in this article.The total content of flavonoids was measured by UV-spectrophotometric method and their anti-oxidation effect was researched.The result showed that the extraction rate of total flavonoids by this process was up to 4.8 times.The method could be used for determining the content of total flavonoids and the average recovery rate of total flavones was 100.6%.The flavoniods from blueberry marc had obviously anti-oxidative activity.
