It has been claimed that consumptions of Abrus cantoniensis (AC) and Abrus mollis (AM) as folk beverages and soups are good to cleanse liver toxicants and prevent liver diseases. There is scant information on the phytochemical profiles and antioxidant activities of these two varieties. Five major phytochemicals in these two cultivars were qualitatively and quantitatively compared using UPLC-PDA. A high level of total phenolic content (TPC) and total flavonoid content (TFC) was found in AC and AM. AC, in general, showed some antioxidant activities comparable to that of BHT, and stronger radical scavenging activities and higher reducing power than that of AM (p<0.05). When principal component analysis (PCA) was applied, high correlation between TPC, TFC and their antioxidant activities was found. Hence, this study proved that, both AC and AM could serve as antioxidant-rich component in foods or beverages to promote health function.
据称，将鸡骨草和毛鸡骨草作为民间饮品和汤品食用，有助于清除肝脏毒素并预防肝脏疾病。关于这两个品种的植物化学特征和抗氧化活性的信息很少。使用超高效液相色谱-光电二极管阵列检测器（UPLC-PDA）对这两个品种中的五种主要植物化学物质进行了定性和定量比较。在鸡骨草和毛鸡骨草中发现了高水平的总酚含量（TPC）和总黄酮含量（TFC）。总体而言，鸡骨草表现出一些与丁基羟基甲苯（BHT）相当的抗氧化活性，并且其自由基清除活性比毛鸡骨草更强，还原能力更高（p<0.05）。当应用主成分分析（PCA）时，发现TPC、TFC与其抗氧化活性之间存在高度相关性。因此，本研究证明，鸡骨草和毛鸡骨草都可以作为食品或饮料中富含抗氧化剂的成分，以促进健康功能。
