title: Phytochemical profiles, antioxidant activities of functional herb Abrus cantoniensis and Abrus mollis.
abstract: 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.
