Abstract
牛樟芝(Antrodia cinnamomea)為台灣特有真菌會寄生在牛樟樹的腐心中,許多研究指出其具有抗腫瘤、抗氧化功能、肝臟保護、抗病毒和免疫調節及抗發炎作用。
而本研究以牛樟椴木、牛樟芝子實體、牛樟芝液態發酵菌絲體為實驗題材進行精油的萃取,實驗目標為找尋本實驗室之前分離自牛樟芝子實體的活性化合物Antrocamphin O、Antrocamphin A、4,7-dimethoxy-5-methyl-1,3-benzodioxole。此三個化合物根據先前的研究,分別具有良好的預防及治療直腸癌的效果、抑制TNFα接受器基因的表現以及高效價的抗發炎活性。以液態發酵或是牛樟椴木的精油找尋這三個化合物的理由是因為使用牛樟芝子實體的成本很高,另外實驗室之前所使用全合成的方式成本也很高,對未來產業發展會有侷限性,所以希望藉由開發其他來源以降低取得這三個化合物的成本。
另一個實驗目標是分析牛樟椴木、牛樟芝子實體、牛樟芝液態發酵菌絲體所含有的精油成分組成,了解這三個樣品中成分的異同,進而了解代謝體間關係。萃取精油的方法是使用改良式水蒸氣蒸餾法,再使用氣相層析串連質譜儀進行分析,配合NIST 14與Wiley 275兩個資料庫,以及使用Kovats Retention Index鑑定其揮發性代謝物的組成。
結果顯示牛樟芝子實體與牛樟木擁有較多相同的化合物,而液態發酵菌絲體的化合物組成與另外兩個樣品較不相同。
