山豆根总碱及其注射剂用 CHCl_3-EtOH-NH_3·H_2O(80:15:5)为展开剂,薄层径向展开可获得15～18个斑点、其中7～8个斑点为生物碱。用 HPLC 制备,以普通硅胶为柱填料,可分离出8个馏分。主要馏分用红外 ATR 法证明为山豆根碱(Dauricine)及去甲山豆根碱(Dauricinoline)。方法简便、快速。
Shandougen total alkaloids and their injections were developed with CHCl 3 -EtOH-NH 3 H 2 O (80:15:5). 15 to 18 spots were obtained when the thin layer was expanded radially, and 7 to 8 spots were alkaloids. Prepared by HPLC, using ordinary silica gel column packing, 8 fractions can be isolated. The main fractions were proved to be Dauricine and Dauricinoline by infrared ATR method. The method is simple and fast.
