台灣南部產沉香木抽出成分之化學主成分研究

Studies on the Main Chemical Composition of Extracts of Aquilaria sinensis Grown in South Taiwan

台灣南部產沉香木之葉部、木質部及樹皮部以甲醇冷浸法萃取，所得濾液經減壓濃縮去除溶劑，再將萃取物以薄層層析法（Thin layer chromatography, TLC）獲取純化之化合物，所得純化之化合物以核磁共振光譜儀（Nuclear magneti-cresonance spectroscopy, NMR）鑑定其成分及結構，發現台灣南部產沉香木6年生葉部之主要化學成分為葉綠素（Aristophyll-C）；木質部之主要化學成分為醯胺類（Amide）之N-反式－對羥基苯乙基阿魏醯胺（N-trans-feruloyltyramine），係此天然物首次在沉香木中發現。 New discoveries were made from a six year-old domestically sown tree in south Taiwan, Aquilaria sinensis. The leafage, the xylem and the bark of Aquilaria sinensis grown in south Taiwan were soaked in methyl alcohol in order to gain the extract. After reducing the pressure concentration, the filtrate obtained through this process removed the solvent. The extract gained through TLC then derived a compound from purification. NMR was then used to authenticate the N compound's ingredient and structure. Aristophyll-C and N-trans-feruloyltyramine were discovered dividedly as the leafage and xylem and the latter main chemical composition for Amide. This natural discovery is an original for Aquilaria sinensis.
