Seven new diterpenoid alkaloids, acotarines A-G (1-7), along with four known diterpenoid alkaloids, were isolated from Aconitum taronense. Their structures were established by 1D, 2D NMR spectra and HRESIMS data. Acotarine A (1) represents a franchetine-type alkaloid characterized by a N-butanone moiety. All the compounds were tested for their activities to induce lysosomal biogenesis through LysoTracker Red staining, compounds acotarines B (2), E (5), F (6), indaconitine (8), 7,8-epoxy-franchetine (9), and 6-epiforesticine (10) showed inducing lysosomal biogenesis activity.
