摘要: 应用HPLC法研究了内蒙草麻黄主产区5种麻黄生物碱的动态变化。5种麻黄生物碱为:麻黄碱(E)、伪麻黄碱(PE)、去甲基麻黄碱(NE)、去甲基伪麻黄碱(NPE)和甲基麻黄碱(ME)。研究结果表明:内蒙东部的草麻黄生长期中E占优势,而在西部PE和E平行或PE高于E,总生物碱在7月中旬和9～10月达高峰。因此影响含量的主要因素是物侯期、降雨量和湿度。对地理位置、气象情况和退化现象等因素也进行了讨论。Abstract: The seasonal variation of 5 active alkaloids, namely: Ephedrine E, Pseudoephedrine PE, Norephedrine NE, Norpseudoephedrine NPE and Methylephedrine ME contained in Ephedra sinica Herba were determined by HPLC. All of specimens were collected from 5 fixed o
