目的从蛇床子 Cnidium monnier中分离逆转肿瘤细胞多药耐药活性成分。方法 用生物活性跟踪法 ,经硅胶柱层析、RP-HPL C等。结果 分离得到 3种活性成分 ,分别为欧芹属素乙 (im peratorin) ,爱得尔庭 (edultin) ,9-异丁酰氧基 -O-乙酰基哥伦比亚苷元 (3′-isobutyryloxy-O-acetyl columbionetin)。结论 体外实验表明 3种化合物对耐药的肿瘤细胞 KBV2 0 0具有明显的逆转作用。

Object To isolate the active compounds on reversing multidrug resistance (MDR) of tumor cell from the ethanol extract in the seeds of Cnidium monnieri (L) Cuss Methods The fractionation directed by bioactivity was carried out with silica gel chromatography and RP HPLC Results Three active coumarins were obtained: imperatorin (Ⅰ), edultin (Ⅱ) and 3′ isobutyryloxy O acetyl columbionetin (Ⅲ) Their sturctures were identified by spectroscopic analysis Conclusion These three compounds have a medium reversing MDR of KBV200 in vitro
