8?-Acet-oxy-14?-benzo-yloxy-N-ethyl-3?,10?,13?,15?-tetra-hydr-oxy-1?,6?,16?-trimeth-oxy-4?-(methoxy-methyl-ene)aconitane: aconifine from Aconitum karakolicum Rapaics.

ABSTRACT: The title compound, C(34)H(47)NO(12), is the norditerpenoid alkaloid aconifine isolated from the leaves and tubers of Aconitum karakolicum Rapaics. It has a lycoctonine carbon skeleton and contains four six-membered rings and two five-membered rings; its geometry is similar to that observed in other lycoctonine-type diterpenoid alkaloids. There are two intra-molecular O-H?O hydrogen bonds which close five- and seven-membered pseudo-rings, respectively. In the crystal, two inter-molecular O-H?O hydrogen bonds cross-link the mol-ecules into double chains along the a axis.
