| 摘要: | 本研究針對蘭科石斛屬(Dendrobium SWARTZ)之化學成分、多醣及真菌等項考察，提供了相關的訊息，作為從事石斛化學成分研究之參考。 延續本研究室對於臺灣蘭科植物的成分之探討，本論文完成三星石斛的成分分析。 從三星石斛(Dendrobium sanseiense HAYATA)莖部分離得到5個化合物，經光譜分析，鑑定為2,3,4,7-tetramethoxyphenanthrene、phytosterol、stigmast-4-en-3-one、heptacosane、hexacosanol。 此外正己烷層抽出物，經GC, GC/MS分析，分別鑑定直鏈烷類、烯類、脂肪酸類等化合物。; This study was based on the investigations and literature survey of phytochemistry, polysaccharide, fungus of Dendrobium genus. This research provided some informations for chemical studies of Shu-hu . In the course of our studies on the constituents of Taiwanese Orchidaceae plants, this study carried out the chemical analysis of Dendrobium sanseiense HAYATA. Five compounds were isolated from the the stems of Dendrobium sanseiense HAYATA. On the basis of spectral analysis, they were identified as 2,3,4,7-tetramethoxyphenanthrene, phytosterol, stigmast-4-en-3-one, heptacosane, and hexacosanol. From GC, GC/MS analysis, long chain alkanes, alkenes, fatty acids were also detected in the fractionated hexane extract, respectively. |
