摘要
目的提取野生刺玫果中的黄酮并探究其性质.方法通过碱性提取法、70%乙醇提取法、热水提取法、60%丙酮提取法进行黄酮的提取.用HCl-镁粉、HCl-锌粉、1%FeCl3-乙醇液、2%AlCl3-乙醇液、1%NaOH与乙醇提取物进行显色反应,采用紫外光谱法对甲醇提取物进行光谱测定,进行定性试验.采用抗氧化实验对黄酮的性质做探究.结果显色反应中呈现黄酮类化合物性质特征颜色,抗氧化性质实验中显示黄酮有一定的抗氧化性.结论野生刺玫中含有一定量黄酮,并且黄酮有多方面功效,具有潜在的营养保健价值.
This study aims to probe into the antioxidant capacity of the flavones extracted from the rose hips. The experimental approaches are as follows: First, the flavones are extracted by employing alkaline-extraction method, 70% ethanol-extraction method, hot-water extraction method, and 60% acetone-extraction method. Second the flavones are allowed to react with color developers respectively such as HCl-Mg powder, HCl-Zn powder, 1% FeCl3 ethanol, 2% AlCl3 ethanol and 1%NaOH and then the spectral reflectance of methanol extracts is measured by applying ultraviolet spectrometry. Finally the capacity of flavones is tested after doing the anti-oxidation experiment. The results show that the extracts from the rose hips present a color characteristic specific to flavonoids and they are also active for oxidation resistance to some extent. All this leads to a conclusion that the rose hips contain a certain amount of flavones which have multiple efficacies and even the potential nutritional value.
