摘要


台灣粗榧((Cephalotaxus wilsoniana Hayata),又稱為威氏粗榧或台灣三尖杉,為粗榧科(Cephalotaxaceae),粗榧屬(Cephalotaxus)的植物,是台灣特有種的稞子植物。 台灣粗榧((Cephalotaxus wilsoniana Hayata)根部,經室溫蔭乾、粉碎後以甲醇浸泡3次,每次7日,過濾後浸泡液減壓濃縮得一甲醇粗萃物,然後利用管柱色層分析、薄層層析、再結晶等方法分離純化之,利用光譜分析鑑定其化學結構,共得9個化合物。 所分離到的化合物有三個固醇類β-sitosterone ( 1 )、β-sitosterol ( 2 ) 、Stigmasterol ( 3 ),一個直鏈類:Fatty acid ( 4 ),四個芳香族類:4-hydroxybenzaldehyde ( 5 )、4-hydroxy-3,5-dimethoxy benzoic acid( 6 ) Benzoic acid ( 7 )、4-hydroxycinnamic acid ( 8 ),及一個雙黃酮類Robustaflavone ( 9 )。其中Robustaflavone及為首次於台灣粗榧中發現。

Cephalotaxus wilsoniana Hayata was Formosan original gymnosperm. The dried stems of Cephalotaxus wilsoniana Hayata were ground and soaked in methanol at ambient temperature. The solution was drained after a 7 day soak period, the residue stems were re-soaked in methanol for 7 days, and the solution re-drained at three times during a 21 day period. The filtered methanolic extracts were combined and concentrated under reduced pressure to a viscous residue. The residue was further isolated and purified by column chromatography, thin layer chromatography and re-crystallization. Nine constituents were found and their structures were established on the basis of spectral analysis and comparison with the literature data. These compounds included three sterols:β-sitosterone ( 1 )、β-sitosterol ( 2 ) 、Stigmasterol ( 3 ) ; one Fatty acid ( 4 ) ;four aromatics:4-hydroxybenzaldehyde ( 5 )、4-hydroxy-3,5-dimethoxy benzoic acid( 6 )、 Benzoic acid ( 7 )、4-hydroxycinnamic acid ( 8 );one flavonoid: Robustaflavone ( 9 ). Among the isolated compounds, Robustaflavone ( 9 ) were the first reported in Cephalotaxus wilsoniana Hayata.
