Abstract
Four compounds were isolated from the root of Dalbergia odorifera T. Chen and identified by chemical and spectroscopic methods as 2′- O-methyl-isoliquiritigenin ( 1), odoriflavene ( 2), 5′-methoxy-vestitol ( 3) and formononetin ( 4). Their antioxidant activities were investigated in lard by the oxidative stability instrument; their inhibitory effects on the decrease of glutathione level of rat lens induced by UV irradiation were studied using a rat lens UV-damage model, and their in vitro cytotoxicity was measured on human SH-SY5Y neuroblastoma cells. Results indicated that all four compounds had obvious antioxidant effects, while none of them showed any synergistic effects on butylated hydroxytoluene or α-tocopherol. When FeCl 3 (4.0 μM) was added, the antioxidant activities of the four compounds markedly decreased. The inhibitory effects of compounds 1, 2 and 4 on the decrease of glutathione level of rat lens induced by UV irradiation were comparable to that of α-tocopherol. All four compounds showed cytotoxic activity when evaluated against a SH-SY5Y cell line in vitro.
