摘 要 ：从土牛膝(Achyraanthes bidentata Bl.)的根中分离到一种新的生物碱——土牛膝碱(ubidenine),通过波谱方法测定出土牛膝碱的化学结构为5,6—二氢化—2,3,10,11—四甲氧基—二苯并[a,g]—喹嗪盐(1)。

Abstract:The EtOH extract of the root of the Chinese herb Achyranthes bidentata B1. was subjected to column chromatography to obtain abidenine (1), a new isoquinoline alkaloid. 1 is bright needle crystals, m. p. 200℃ (dec). Its structure was elucidated through spectroscopic methods as 5,6-dihydro-2,3,10,11-tetramethoxy-dibenzo [a,g] quino-lizinium (1).
