Popis: | Two triterpenoids, euphol and tirucallol were isolated from Kansui Radix ( Euphorbia kansuiLiou, 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%, respectiv ely. 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%. |
