摘 要:采用TLC法定性鉴别维吾尔药材苦豆子,建立HPLC法测定其中的氧化槐果碱(1)和氧化苦参碱(2)。以氯仿∶甲醇∶浓氨试液(40∶10∶1)为展开剂,TLC结果显示苦豆子中的1、2和槐定碱有效分离。HPLC法采用氨基柱,以乙腈∶无水乙醇∶3%磷酸(80∶10∶10)为流动相,检测波长205 nm。1和2均在5~500μg/ml浓度范围内线性关系良好。平均回收率为100.5%和104.7%,RSD为1.26%和1.32%。A TLC method and an HPLC method were established for the identification of the Uighur medicinal herb Sophora alopecuroides L. and the determination of oxysophocarpine (1) and oxymatrine (2), respectively. The TLC results showed that compounds 1, 2 and sophoridine could achieve an effective separation with the developers of chloroform : methanol : concentrated ammonia solution (40 : 10 : 1). For the HPLC method, an NH2 column was used, with the mobile phase of acetonitrile : absolute ethanol : 3 % phosphoric acid (80 : 10 : 10), at the detection wavelength of 205 nm. The calibration curves for both 1 and 2 were linear in the concentration range of 5 - 500 μg/ml. Their average recoveries were 100.5% and 104.7%, with RSDs of 1.26% and 1.32%, respectively.
