2-Oxopomolic acid shows cytotoxic activity, it shows a significant decrease in intracellular melanin content in B16-F10 cells, and in culture media melanin. 2-Oxopomolic acid shows radical-scavenging activities similar to that of the reference antioxidant
8-Hydroxypinoresinol has antioxidant activity,it and phillygenin significantly reduce the cell injury by 3-morpholinosydnonimine (SIN-1), a ONOO- generator, may be useful for the therapeutic or preventive applications in treating ONOO--related diseases.
