Fig. 2From: Phytoestrogen (+)-pinoresinol exerts antitumor activity in breast cancer cells with different oestrogen receptor statusesABTS radical scavenging assay. ABTS●+ radical scavenging activity of (+)-pinoresinol a or TroloxTM b at concentrations between 0.01and 1000 μM and 50 and 800 μM, respectively. Data are expressed as the absorbance of ABTS●+, which was read at 734 nm for 2 h. Measurements were performed in triplicate in three independent experimentsBack to article page
