Abstract
自95年起愷他命緝獲量已連續五年名列第一,儼然已成為濫用藥物者的新寵。雖然「濫用藥物尿液檢驗作業準則」明定尿液中愷他命之代謝物(愷他命、去甲基愷他命)確認檢驗方法與閾值濃度,但含量較高之代謝物-去氫去甲基愷他命有被檢測之必要性,卻尚未規範於法規中。本研究以尿液中愷他命類代謝物-愷他命、去甲基愷他命及去氫去甲基愷他命為待測物,調整適合層析出愷他命類代謝物之升溫條件,並比較三種不同固相萃取管柱對愷他命類代謝物萃取表現,將固相萃取技術及氣相層析質譜儀分析條件最佳化、正確定量其濃度,並使用經液相層析電噴灑串聯質譜儀檢出愷他命與去甲基愷他命成分之尿液檢體,檢測其愷他命類代謝物之表現情形。結果顯示本分析方法操作簡單、快速、靈敏、穩定,對三種待測物能提供理想的檢量線線性(濃度範圍40至2000 ng/mL,各待測物之r2 皆大於0.990)、敏感度(各待測物之最低可定量濃度皆可至15 ng/mL)、準確度(93.4-101.1%)及精密度 (RSD<9.5%),本方法應可應用於濫用藥物尿液檢驗實務工作。
