采用β-胡萝卜素漂白法和ABTS自由基阳离子分析法研究了赤子菜和蒲桃鲜、干提取物的抗氧化活性。使用这两种试验的所有提取物样品的抗氧化活性的百分比为58%至80%。两种植物的新鲜样品比干燥样品具有更高的抗氧化活性。β-胡萝卜素漂白试验的结果与ABTS试验的结果相关（R-2 = 0.9849）。
The antioxidant activity of fresh and dried plant extracts of Paederia foetida and Syzygium aqueum were studied using beta-carotene bleaching and the 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) ( ABTS) radical cation assay. The percentage of antioxidant activity for all extract samples using both assays was between 58 and 80%. The fresh samples of both plants had higher antioxidant activity than the dried samples. The results of the beta-carotene bleaching assay were correlated (R-2 = 0.9849) with those of the ABTS assay.
