摘要

Two new alkaloids, aconicarmine (1) and aconicaramide (5), were isolated from the EtOH extract of the lateral roots of Aconitum carmichaelii, together with five known compounds: fuziline (2), neoline (3), N-ethylhokbusine B (4), 5-hydroxymethylpyrrole-2-carbaldehyde (6), and oleracein E (7). Their structures were elucidated by physical and NMR analysis. Pyrrole alkaloids were isolated from A. carmichaelii for the first time. In the in vitro assays, compounds 2 and 3 showed activity against pentobarbital sodium-induced cardiomyocytes damage by obviously recovering beating rhythm and increasing the cell viability, while compounds 5 and 7 showed moderate antibacterial activity.
