Abstract:
Two new 2-(quinonylcarboxamino)benzoates, named aconicarmiquinamides A (1) and B (2), were isolated from an aqueous extract of the lateral roots of Aconitum carmichaelii. Their structures were determined by spectroscopic data analysis, and confirmed by comparison with synthetic methyl 3,6-bis(diethylamino)benzoqunonylcarboxylate (3).
