    Abstract: 康復力 (Symphytum officinale Linn.),在傳統中草藥中具有抗氧化抗發炎和抗癌等功效。本研究收集台灣各地的康復力,檢測其所含具肝毒性及致癌性之雙稠吡咯啶類生物鹼 (pyrrolizidine alkaloids;PAs) 種類及其含量。以氣相層析質譜儀(Gas Chromatography-Mass Spectrometry) 方法分析康復力樣品,結果測得二種類型共九種不同PA成份 :(一) retronecine 類型,包含lycopsamine、intermedine、myoscorpine、echiumine、symlandine、symphytine、echimidine等PAs ; (二) heliotridine 類型,包含7-angeloylheliotridine、heliosupine等PAs。本實驗定量以monocrotaline為標準品製作檢量線,濃度為 50~400 μg/mL,線性相關係數(R2)為0.9994。以methyl myristate 作為內標準品。定量分析結果康復力中PAs 總含量為 3.33~100 μg/g Herb。本研究可提供消費者使用中草藥康復力的用藥安全警告資訊,以確保國人之健康。
