中文摘要 | 本研究針對甘遂藥材中triterpenoid 成分,分離純化而得euphol 及tirucallol 二成分作為指標成分,利用GC-MS探討其定量方法,並調查市售甘遂藥材之指標成分含量。 GC-MS使用毛細管柱(HP-5MS),以euphol(50.0~400.0 μg/mL)及tirucallol(0.0~200.0 μg/mL)做為對照用標準品。其線性迴歸方程式及相關係數(r)分別為euphol : y = 17.12x + 24.71(r = 0.9988); tirucallol: y = 15.44x + 11.35 (r = 0.9976),均呈良好線性關係。二種指標成分之回收率,分別為euphol 98.3 ±1.2% , tirucallol 84.8 ± 1.2% 。同日內及異日間相對標準偏差試驗,其同日內為0.90~3.07 % ,異日間為3.93~8.17% 。 測定七件市售甘遂藥材中二種指標成分之含量。結果euphol 之含量平均為0.14%(0.10~0.19%); tirucallol之含量平均為0.06%(0.05~0.07%)。 |
英文摘要 | Two triterpenoids, euphol and tirucallol were isolated from Kansui Radix (Euphorbia kansui Liou, Euphorbiaceae) by a modified isolation method. These constituents were used as marker substances for quality control of Kansui Radix using a home-developed gas chromatography- mass spectrometry (GC-MS) method. The linear calibration ranges were 50.0-400.0 μg/mL (r=0.9988) for euphol and 20.0-200.0 μg/mL (r=0.9976) for tirucallol. The relative standard deviations of two marker substances for intraday and interday analyses were 0.90-3.07% and 3.93-8.17%, respectively. Recoveries were euphol 98.3±1.2%, and tirucallol 84.8±.0%. The contents of two marker substances in seven crude drugs of Kansui Radix were euphol 0.10-0.19%, and tirucallol 0.05-0.07%. |
