A new aromatic amide, methyl-N-(3-carbamoylpropionyl) anthranilate was isolated for the first time as a natural compound and one known $C_{19}-diterpene\;alkaloid$, avadharidine was also obtained from the root of Aconitum pseudolaeve var. erectum. The\;LD_{50}$ values of water extract and MeOH extract of the root of Aconitum pseudolaeve var. erectum in mice were 1. 23 g (13. 6 g crude drug) and 0. 77 g(5. 13 g crude drug)/kg, p.o., respectively.
