Fig. 4 in Multiple free radical scavenging reactions of aurones

Fig. 4. The mechanisms proposed for the radical scavenge reaction of sulfuretin (compound 5) in different phases. The arrows in black color indicate the most likely reaction mechanism in the gas and benzene phases. Those in magenda color indicate the most likely reaction mechanism in the water phase. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
