摘要
利用溶剂提取法对花果山"糯米茶"中的黄酮化合物进行提取,并利用硅胶柱色谱分离法对其进行分离纯化,同时通过DPPH抗氧化活性体外评价体系测定其清除自由基的能力。结果显示,"糯米茶"中的黄酮化合物具有一定的的清除DPPH自由基的能力,"糯米茶"是可开发的抗衰老、抗氧化的保健茶。
Flavonoids were extracted from glutinous rice tea grown in Huaguo Mountain by solvent extraction and isolated by column chromatography on silica gel. The antioxidant activity in vitro was determined by DPPH free radical scavenging assay. The results indicated that flavonoids from glutinous rice tea had certain free radical scavenging ability. In conclusion, glutinous rice tea has the potential to be developed as an anti-aging and antioxidant health-care tea.
