    Abstract: 耳?草 (Heliotropium indicum L.) 在近代研究中指出具有治療肺炎,肝病和抗癌等功效,本研究為收集台灣地區各地之耳?草,以氣相層析質譜儀 (GC/MS) 檢測其是否含有具肝毒性及致癌性之?咯啶生物鹼 (pyrrolizidine alkaloids) ,實驗分為全株及耳?草各器官之檢驗,而萃取方法為酸水萃取,再經由固相萃取純化,最後經由氣相層析質譜儀分析。經實驗結果顯示,耳?草至少含有四種?咯啶生物鹼,分別為indicine 、 lycopsamine 、一未知的?咯啶生物鹼,以及3'- acetylindicine / 3'- acetyllycopsamine,本實驗定量以 monocrotaline 為標準品,檢量線濃度範圍為 50-400 μg/mL,內標準品為 methyl myristate ,經定量實驗結果顯示,耳?草內之?咯啶生物鹼大多集中在花部,而indicine 為耳?草內主要之?咯啶生物鹼,其總含量最高為 1.95 μg/g herb 。利用本研究之實驗結果,建立一套檢測中草藥所含?咯啶生物鹼之研究方法,以確保民眾服用中草藥的安全,並進一步的進行中草藥之風險評估。
