Abstract

Two new alkaloids, Septonine (C35H44N2O9) and Septontrionine (C25H39NO6) were isolated from the roots of Aconitum septentrionale K. According to the 1H and 13C NMR, IR, and mass spectra, Septonin and Septontrionin were assigned the structures of 20-ethyl-7-hydroxy-1α,14α,16β-trimethoxy-6-oxo-17(7→8)abeoaconitan-4-ylmethyl 2-(2,5-dioxopyrrolidin-l-yl)benzoate and 20-ethyl-7-hydroxy-1α,14α,16β-trimethoxy-4-methoxymethyl-17(7→8)abeoaconitan-6-one, respectively.
