Two new imidazole alkaloids (lepidiline A and lepidiline B) have been isolated from a root extract of Lepidium meyenii with the common name Maca and identified as 1,3-dibenzyl-4,5-dimethylimidazolium chloride (1) and 1,3-dibenzyl-2,4,5-trimethylimidazolium chloride (2), respectively. The structures of these two new compounds were determined by spectroscopic methods, as well as single-crystal X-ray diffraction performed on compound 1.
从有着俗名玛卡的秘鲁玛卡根提取物中分离出了两种新的咪唑生物碱（利比地林A和利比地林B），它们分别被鉴定为1,3 - 二苄基 - 4,5 - 二甲基咪唑氯化物（1）和1,3 - 二苄基 - 2,4,5 - 三甲基咪唑氯化物（2）。这两种新化合物的结构通过光谱方法以及对化合物1进行的单晶X射线衍射得以确定。
