Chemical studies of the radical scavenging mechanism of bisorbicillinol using the 1,1-diphenyl-2-picrylhydrazyl radical.
A potent antioxidant, bisorbicillinol, which is a member of the bisorbicillinoid family isolated from the culture broth of Trichoderma sp. USF-2690, produces a stable radical-terminated symmetric dimer by donating two hydrogen atoms to the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical.
