Radical scavenging and cytotoxic activities of phenolic acids

Data show the amount of PAs needed to capture 90 percent of free radicals and inhibit only 10 percent of normal kidney cells (non-cytotoxic doses). CA possesses the best radical-scavenging activity but also is the most cytotoxic. Values (µg/ml) represent the mean and standard deviation of triplicate measurements
