| 中文摘要 | 試驗用杉木心材,以水蒸氣蒸餾法抽取精油,精油中成分用column chromatography分離,並純化獲得3種成分,成分鑑定配合GC, GC-MS,證實為α-cedrene, α-terpineol及α-cedorl,分別將分離出3種成分,對歐洲室塵蟎(DP),美洲室塵蟎(DF)及熱帶無爪塵蟎(BT)進行抗 活性,結果發現α-terpineol對3種塵蟎抗 活性最好,α-cedrol對歐洲室塵蟎效果最好,美洲室塵蟎次之,α-cedrene僅對熱帶無爪蟎有效。杉木心材精油對歐洲室塵蟎及熱帶無爪塵蟎抗蟎效果顯著。 |
| 英文摘要 | The essential oil in the heartwood of Cunninghamia lanceolata was extracted and separated with a water steaming distillation method followed by column chromatography. Three major components, i.e., α-cedrene, α-terpineol, and α-cedrol, were obtained through identification by gas chromatography (GC) and gas chromatograph-mass spectrophotometry (GC-MS). They were then used to test their antimite activities against Dermatophagoides pteronyssinuss, D. farinae, and Blomia tropicatus. Results showed that α-terpineol was generally the best at killing the 3 mites, and α-cedrol was most effective in killing D. pteronyssinuss. It was somewhat less effective against D. farinae, while α-cedrene was only promising for killing B. tropicatus. The essential oil of C. lanceolata heartwood is effective in suppressing D. pteronyssinuss and B. tropicatus. |
