چکیده
THE TITLE COMPOUND (SYSTEMATIC NAME 8β-acet-oxy-14α-benzo-yloxy-N-ethyl-13β,15α-dihydr-oxy-1α,6α,16β-trimeth-oxy-4β-methoxy-methyl-eneaconitane), C(34)H(47)NO(10), is a typical aconitine-type C(19)-diterpenoid alkaloid, and was isolated from the roots of the Aconitum carmichaeli Debx. The mol-ecule has an aconitine carbon skeleton with four six-membered rings and two five-membered rings, whose geometry is similar to these observed in other C(19)-diterpenoid alkaloids; both of five-membered rings have the envelope configurations and the six-membered N-containing heterocyclic ring displays a chair conformation. Intra-molecular O-H⋯O hydrogen bonding occurs. Weak inter-molecular C-H⋯O hydrogen bonding is observed in the crystal structure.
