摘要
将红枣核以60%乙醇提取后,经AB-8大孔吸附树脂吸附分离,首次研究了红枣核类黄酮对DPPH自由基的清除活性。结果表明,红枣核类黄酮对DPPH自由基有很强的清除活性,IC50为6.5μg/ml,对DPPH自由基的清除率有量效关系。
Flavonoids from jujube pit were extracted with 60% percent ethanol and separated by AB-8 macroporous adsorption resin.DPPH free radical scavenging efficiency of flavonoids from jujube pit was studied first in this experiment. The results showed that the flavonoids from jujube pit have powerful scavenging efficiency to DPPH free radical. Its IC50 is 6.5μg/ml. The increase in the degree of DPPH free radical scavenging efficiency of flavonoids from jujube is concentration dependent.
