Hydroxyl radical scavenging activity
The hydroxyl radical has a very short in vivo half-life. This makes it a very dangerous compound to the organism
[16]. Most hydroxyl radicals are produced from the decomposition of hydro peroxides (ROOH). As shown in Fig. 3,
the scavenging capacity of the safflower is weak at low concentrations, but increases quickly with higher
concentrations. Results showed that the safflower has a high level of hydroxyl radical scavenging effect.
