Abstract:
The gas phase fumigation was used to study the vapor antibacterial activity of ten plant essential oils, namely pine needle oil, citronella oil, Ylang oil, Kang Niangke oil, Litsea cubeba oil, curcuma zedoary oil, sage oil, agarwood oil, mugwort oil, rosemary oil, against Pseudomonas aeruginosa. Antibacterial effects were compared by measuring the minimum inhibitory concentration (MIC). Results showed that Litsea cubeba oil and citronella oil presented the best inhibitory effects against Pseudomonas aeruginosa, the MIC of which were 250 μL/L, followed by sage oil and ylang oil with MIC of 500 μL/L. The MIC of mugwort oil, curcuma zedoary oil and rosemary oil were 1000 μL/L. Pine needle oil, Kang Niangke oil and agarwood oil showed no obvious antibacterial activities. When the compound ratio of Litsea cubeba oil and citronella oil was 2:3 or 3:2, they appeared significant synergistic effects. When the space volume concentration was 100 μL/L, the compound completely inhibited the growth of Pseudomonas aeruginosa. Different solvents had different antimicrobial activities on the compound essential oils, among which ice acetic acid had the best effect, followed by ethanol.
