[Abstract] In this study, the authors investigated essential oils that were extracted from timber from thinning for antibacterial activity, bacterial elimination, and antioxidant activity aiming for effective use of the oils. The oils were found to be antibacterial against gram positive (Staphylococcus aureus) and gram negative (Escherichia coli and Pseudomonas aeruginosa) bacteria. The antibacterial activities of the oils were re-examined by classifying the oils in Groups A to D ; and the chemical components of Group A, which showed antibacterial activity to all three bacteria, were analyzed. The main component was identified to be (+)-α-pinene (GC: 96.73%), which was shown to be involved in the expression of antibacterial activity. Bacterial elimination by the oils was tested by the hand washing method. The viable cell count was 88 in Group A compared to 668 in the control, showing strong bacterial elimination by the oils. The authors then tested the availability of (-)-Epicubenol, which is a terpenoid contained in the oils, as a cosmetic ingredient. In a whitening effect test, which measured the inhibition of L-DOPA oxidation, (-)-Epicubenol showed an inhibition rate of 7.7%, which is higher than that of Arbutin (4.0%). The authors also disclosed that (-)-Epicubenol inhibits the enzymatic activity of tyrosinase between L-DOPA and DOPA quinine. The results suggest that essential oils from thinned wood contain useful components and are likely useful in many fields. |
