The antioxidant activities of ten natural p ‐terphenyl derivatives, 1 – 10 , obtained from the fruiting bodies of three edible mushrooms ( Thelephora ganbajun, Thelephora aurantiotincta, Boletopsis grisea ) indigenous to China were evaluated in comparison with BHA (‘butylated hydroxyanisole’=(1,1‐dimethylethyl)‐4‐methoxyphenol) and α ‐tocopherol by the DPPH (‘1,1‐diphenyl‐2‐picrylhydrazyl’=2,2‐diphenyl‐1‐(2,4,6‐trinitrophenyl)hydrazyl) radical‐scavenging method. The compounds 1 – 3 showed significant antioxidant activity. The antioxidant activities of compounds 1 – 10 and reference compounds followed the order: 2 >BHA> 1 > 3 > α ‐tocopherol> 10 > 9 > 6 > 5 > 8 > 7 > 4 . The compound 2 exhibited the strongest radical‐scavenging activity with an EC 50 value of 0.07 ( EC 50 (BHA) 0.09; EC 50 ( α ‐tocopherol) 0.25).
