中文摘要 | 採集七種桉樹之成熟葉,以水蒸氣蒸餾法提取精油,經分別測定其含量及主要成 分,再將其稀釋後加入木粉與濾紙中,進行防治白蟻效能測定,結果顯示:以藍桉與玫瑰桉 之抑制白蟻效能最優,其次為檸檬桉、尾葉桉與細葉桉,其餘則較差。不同濃度之溶液其防 治效能,以2%之效果最良好,0.25%則不具效應。各種主要成分之防治白蟻效果,以α-松 油精最佳,其次為安息茴香油精與1,8-桉葉精。 |
英文摘要 | Mature leaves of 7 species of Eucalyptus were collected and steam distilled to obtain their essential oils. The content and compositions of the oils were determined separately. Filter paper and wood flours steeped with the oils were tested for their termite resistance. The results indicated that Eucalyptus grandis and E. globules oils exhibited the highest termite resistance, followed by E. citriodora and E. urophylla oils. The other oils were less effective. Test on varying oil concentrations indicated that 2% of the oils gave the best results, while concentrations less than 0.25% showed virtually no termite repelling effect. Effective antiter-mite components among the oils were identified, α-pinene was found as the most effective, followed by p-cymene and 1,8-cineole, while the other components less effective. |
