    摘要: 將馬兜鈴植物(Aristolochia kamkauensis Sasaki)陰乾後,分別以丙酮和四氧夫喃萃取。丙酮萃取液以下列條件利用高速液相層析儀定量。管柱(分離管) : μ-porasil;動相:正己烷一丙酮一氯仿9 : 3 : 1 (V : V : V) ;偵測儀:紫外光偵測儀波長365mm ;流速:每分鐘1毫升。所得結果相對標準偏差分別為天仙藤10.0%,馬兜鈴植物根部5 % ,莖部4.2% ,四氫夫喃萃取液另加入天然色素( Rubropunctatin )為內部標準品以下列條件定量:管柱: μ- porasil ;‘動向:正己烷一四氫夫喃一正丙醇,35 : 10 : 4 (V :V :V);流速:每分鍾1毫升;偵測波長紫外光254 nm。所得結果之相對標準偏差分別為天仙藤4.5%,馬兜鈴植物莖部3.0% ,根部4.4%,以不同萃取溶劑、動相、偵測波長所得結果大致相同,但可看出加入內部標準品之定量法可得較精密之結果。
