翅碱蓬分布在沿海滩涂地区,其幼芽广泛的被当地居民食用,本研究为了考察翅碱蓬资源的可利用性,对不同生长时期的翅碱蓬总黄酮含量进行了比较,采用不同的方法(DPPH·、OH·、ABTS+·)评价了翅碱蓬黄酮提取物的抗氧化活性.试验结果表明:翅碱蓬的总黄酮含量在花期达到最大,为14.37 mg/g.抗氧化结果表明,翅碱蓬黄酮提取液对DPPH·、OH·、ABTS+·均表现较强的清除效果,同时发现,翅碱蓬对DPPH·的清除率到达最大为94.37%,对OH·的最大清除率为84.29%,对ABTS+·的最大清除率为93.30%.因此,翅碱蓬是一种具有开发天然抗氧化剂潜力的植物,其不仅能在盐碱地区广泛生长改善生态环境,而且还将会有更大的生物利用价值.%Saline seepweed distribute in coastal area , the buds are widely consumed by the local population. This study in order to investigate the effect of saline seepweed resource availability , comparing the content of total flavonoids in suaeda salsa with different growth periods.Using different methods (DPPH·, hydroxyl radicals, ABTS+·) to evaluate the antioxidant activity of flavonoids extracted from saline seepweed. The results showed that the maximum content of total flavonoids extracted from saline seepweed was in florescence , 14.37 mg/g. Flavonoids extracted from saline seepweed leaves in different growth possessed strong capability of eliminating DPPH·, ·OH, ABTS+·. The maximum scavenge ability of flavonoids extracted from saline seepweed leaves against DPPH·, hydroxyl radicals, ABTS+·were 94.37%,84.29%,93.30%, respectively. Therefore, saline seepweed is a kind of natural antioxidant potential of the plant , which not only can grow in saline alkali area , improve the ecological environment, but also will have greater biological utilization value.
