松针落叶中含有大量的黄酮类化合物,研究发现松针黄酮对各种自由基均有较强清除作用,总体抗氧化活性很强,对金属离子有很好的螯合作用,并可以在一定程度上抵抗蛋白质的羰基化氧化。但在不同的浓度、温度、pH值等条件下,其表现出的抗氧化活性却差异很大。试验结果表明,松针黄酮的抗氧化性能总体强于Vc,同时又验证了其与Vc有良好的协同作用。 Pine needles contain large amounts of flavonoids, the study found that pine needles on all kinds of free radicals have a strong scavenging effect, the overall antioxidant activity is very strong, good chelation of metal ions, and to some extent Resistance to protein carbonylation. However, at different concentrations, temperature, pH and other conditions, the antioxidant activity showed great differences. The test results show that the antioxidant properties of pine needles overall stronger than the Vc, and verified its Vc has a good synergistic effect.
