The title compound, (1α,3α,6α,14α,15α,16β)-3,8,13,14,15-penta­hydr­oxy-1,6,16-trimeth­oxy-4-methoxy­methyl-20-methyl­acon­itan-8,14-diyl 8-acetate 14-benzoate, C33H45NO11, a C19 diterpenoid alkaloid, obtained from the roots of Aconitum kusnezoffii, has been crystallographically characterized in this study. Rings A, B and E have chair conformations, rings C and F display envelope conformations, and ring D adopts a boat conformation. There are inter- and intra­molecular O—H⋯O hydrogen bonds, the latter resulting in the formation of a non-planar seven-membered ring. The inter­molecular inter­actions link the mol­ecules into a two-dimensional network.

The title compound, C17H17FN2O4, is of inter­est due to its potential pharmaceutical and agrochemical activity. All three meth­oxy groups are twisted with respect to the attached aromatic ring [C—C—O—C torsion angles = 10.43 (18), 97.38 (14), −19.34 (17)°] and the phenyl ring makes a dihedral angle of 40.6 (2)° with the plane through the remaining atoms in the mol­ecule. Inter­molecular N—H⋯O hydrogen bonds link the mol­ecules into chains running along the c axis.
