چکیده
THE TITLE COMPOUND [SYSTEMATIC NAME: (1α,3α,6α,8β,13β,14α,16β)-20-ethyl-8-eth-oxy-3,13-dihy-droxy-1,6,16-trimeth-oxy-4-(meth-oxy-meth-yl)aconitan-14-yl 4-meth-oxy-benzoate], C(35)H(51)NO(10), was isolated from roots of Aconitum carmichaeli Debx., which is a typical C(19)-diterpenoid alkaloid. The mol-ecule has an aconitane carbon skeleton with four six-membered rings and two five-membered rings. The six-membered rings adopt chair conformations or boat conformations, while the five-membered rings have envelope conformations. Intra-molecular O-H⋯O and O-H⋯N hydrogen bonds help to stabilize the mol-ecular structure. Weak inter-molecular C-H⋯O inter-actions occur in the crystal structure.
