Three new C19-diterpenoid alkaloids vilmotenitines A-C (1-3), together with seven known ones, vilmorine D (4), talatizidine (5), isotalatizidine (6), vilmorrianine B (7), vilmorrianine D (8), talatizamine (9), 8-deacetyl-yunaconitine (10), were isolated from Aconitum vilmorinianum var. patentipilum. Vilmotenitines A (1) and B (2) are the second natural occurrences of C19-diterpenoid alkaloids with a unique rearranged six-membered B ring formed by the C(8)-C(10) linkage. © 2015 Published by Elsevier B.V.
