苦荞芽中黄酮类化合物含量及其抗氧化性的研究

Development on Flavonoids and Antioxidant Activity of Tartary Buckwheat Sprout

摘要:

以反相高效液相色谱法测定苦荞在发芽过程中芦丁和槲皮素含量变化，采用分光光度法测定苦荞种子及其苦荞芽提取物对DPPH自由基和ABTS自由基的清除能力。结果表明，苦荞发芽第1~10 d范围内，黄酮类物质含量逐渐升高，在第10 d时达到最大值；且苦荞发芽后其抗氧化性较种子有明显的提高。

Abstract:

Rutin and quercetin content in tartary buckwheat sprout were analyzed by HPLC. The DPPH and ABTS radical scavenging capacity of tartary buckwheat seed and sprout ware measured by spectrophotometry. The results showed that the dynamic changes of flavonoids in tartary buckwheat were increased on day 1 to 10 and reach its peak on day 10. After germination, the antioxidant capacity of tartary buckwheat sprout had significantly improved.
