The antioxidant activity in vitro of three poly(phenylacetyloxy)-substituted 1,1':4',1"-terphenyl compounds from the edible mushroom Thelephora ganbajun were investigated. The IC50 values of compounds 1-3 for lipid peroxidation in rat liver homogenate were 400, 48, 54 microM, respectively. Compounds 1-3 increased superoxide dismutase (SOD) activity with EC50 values of 182, 74, 204 microM. They were also assessed on the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity with EC50 values of 49, 1233, 55 microM.
对采自食用菌干巴菌的三种聚（苯乙酰氧基）取代的1,1':4',1''-三联苯化合物的体外抗氧化活性进行了研究。化合物1-3对大鼠肝匀浆脂质过氧化的IC50值分别为400、48、54微摩尔。化合物1-3使超氧化物歧化酶（SOD）活性增加，其EC50值为182、74、204微摩尔。还对它们的1,1-二苯基-2-苦基肼（DPPH）自由基清除活性进行了评估，其EC50值为49、1233、55微摩尔。
