摘要

芳香氣味為木材重要特徵，本研究選擇三種具特殊香味且為國人所熟悉之三種針葉樹材，包括臺灣杉、杉木及臺灣扁柏，利用管柱層析、高效能液相層析分離及純化具芳香味道之抽出成分，再以質譜、紅外線光譜及核磁共振光譜分析作結構鑑定。試驗結果顯示，臺灣杉主要香味成分為T-cadinol，T-muurolol及α-cadinol；由杉木鉋切面收集具有與杉木相同香味之針狀結晶為cedrol；此外，由臺灣扁柏分離所得特殊香味之油狀物，經HPLC純化後分析，證實主要成分為α-terpineol及α-cadinol。

Fragrance is one of the distinctive characteristics of wood. In this study, the fragrant constituents of three coniferous woods grown in Taiwan, namely Taiwania cryptomerioides, Cunninghamia lanceolata, and Chamaecyparis obtuse var. formosana, were investigated. Three kinds of fragrant cadinane type terpenoids, including T-cadinol, T-muurolol and α-cadinol, were isolated and identified from Taiwania cryptomerioides. Fragrant needle-like crystals collected from sawn and dried cross-section surface of Cunninghamia lanceolata were identified as cedrol. In addition, two fragrant constituents, α-terpineol and α-cadinol, were isolated and identified from Chamaecyparis obtusa var. formosana.
