The biological activities of Oenothera laciniata extracts were measured, including antioxidant activity and cytotoxic effects. O. laciniata is an endemic species of Jeju Island, Korea with a seaside habitat. The concentration of total polyphenolic compounds from ethanol (EtOH), n-hexane, dichloromethane ($CH_2Cl_2$), ethylacetate (EtOAc), butanol (BuOH), and water fractions of O. laciniata was 63.96, 8.49, 28.11, 172.64, 114.56, and 34.91 mg/g, respectively. The EtOAc fraction contained the highest antioxidative activities ($IC_{50}$), measured as follows: 16.19 ${\mu}g/mL$ in DPPH radical scavenging capacity, 220.37 ${\mu}g/mL$ in xanthine oxidase inhibitory activity, 42.07${\mu}g/mL$ in superoxide radical scavenging capacity, and 421.33 ${\mu}g/mL$ in nitric oxide scavenging capacity. The cytotoxicity of O. laciniata extracts was examined through their effect on the growth of HL-60 cells. Incubation of HL-60 cells with the EtOAc fraction resulted in the greatest inhibition of cell growth; high DNA fragmentation and numerous sub-G1 hypodiploid cells were observed in HL-60 cell cultures treated with the EtOAc fraction. These results suggest that the EtOAc fraction of O. laciniata has potent apoptotic and antioxidative activities in vitro.
