The volatile aroma compounds of Korean green tea were analyzed and identified. The main aroma compounds of it included geraniol, benzyl alcohol, 2-phenylethanol, β-ionone, benzyl cyanide, cis-jasmone and indole. The main volatile components identified from Korean green tea were tested for the antimutagenic activities against aflatoxin B₁(AFB₁) and N-methyl-N´-nitro-N-nitrosoguanidine(MNNG) using their authentic compounds. Strong antimutagenic activities toward AFB₁and MNNG were observed when trans-2-hexenol, linalool, geraniol, nerolidol and indole were added in Salmonella typhimurium TA100. Benzyl cyanide and cis-jasmone showed antimutagenic activity against more AFB₁than MNNG, but furfuryl alcohol, cis-3-hexenol and linalool oxide showed antimutagenic activities against more MNNG than AFB1.
