Fig. 2From: Effects of Antrodia camphorata extracts on anti-oxidation, anti-mutagenesis and protection of DNA against hydroxyl radical damageResults of antimutagenic testing against mutagen 4-NQNO and B[a]P by Anthrodia camphorata extract. Data are expressed as mean ± SD (n = 3). Inhibition rate (%) = [1−number of His+ revertants in the presence of A. camphorata extract/number of His+ revertants in the absence of A. camphorata extract] × 100 %Back to article page
