Abstract: The antibacterial activities of eugenol in vitro to 12 kinds of bacteria were tested by micro-volume broth dilution method, respectively. The results showed that the eugenol possesses the highest antibacterial activity against E.coli ATCC259 22 (MIC is 5 μg/ml and MBC is 10 μg/ml) and the lowest antibacterial Bacillus circulans (MIC is 320 μg/ml and MBC is 640 μg/ ml), and the MICs and MBCs of other bacteria are between 20 μg/ml and 80 μg/ml and between 40 μg/ml and 160 μg/ml, respectively. The time-bactericide curve indicated that the antibacterial activity of eugenol shows strong concentration dependent and slight time dependent. The eugenol with high antibacterial property is worthy to be researched as a sort of potential natural preservative substance.
