摘要: 在超声辅助下从“黑美人”马铃薯中提取原花青素,提取浓缩液经AB-8大孔吸附树脂填充柱纯化后,所得产物中原花青素含量为93.59%,得率为4.3%。抗氧化性研究表明,其对DPPH·自由基、·OH自由基和O2·-自由基具有显著的清除效果,清除率与其浓度成正相关,且不输于VC,尤其是对·OH自由基和O2·-自由基的清除作用明显高于VC。表明 “黑美人”马铃薯原花青素有较强的抗氧化性,这为进一步开发利用“黑美人”马铃薯提供必要的理论支持。

Abstract: Proanthocyandins were ultrasonically extracted from “Black Beauty” potatoes and further separated by AB-8 macroporous resin.The concentration of proanthocyandins in the purified extract was 93.59%,and the yield of proanthocyandins was determined to be 4.3%.Proanthocyandins of “Black Beauty” potatoes had strong scavenging effects against DPPH radicals,·OH radicals and O2radicals.The scavenging rates of proanthocyandins were positively related to its concentration,and did not lower than that of Vc.The scavenging effects against ·OH radicals and O2 radicals were obviously higher than that of Vc.This study provided theoretical basis for further development and utilization to proanthocyanidins from “Black Beauty” potatoes.
