The title compound (delgradine), C41H43NO12, is a hetisine-type C20-diterpenoid alkaloid, isolated from the roots of Aconitum carmichaeli Debx. In the the molecule assumes an U-shaped conformation, the terminal benzene rings being approximately parallel and partially overlapped with each other. The molecule contains eight alicyclic and heterocyclic rings. Cyclohexane rings A and B adopt similar chair conformations; the six-membered rings C, D and E form a bicyclo[2.2.2]octane system with a boat conformation for each six-membered ring, the six-membered heterocyclic ring F has a screw-boat conformation and both of the five-membered rings G and H have envelope conformations. The contains intermolecular O—H⋯O hydrogen bonding.

The title compound was isolated from the roots of Aconitum carmichaeli Debx and crystals suitable for X-ray structure analysis were obtained by slow evaporation from an acetone solution at room temperature.
H atoms were located geometrically with C—H distance of 0.93–0.98 Å, and refined using a riding model with Uiso(H) = 1.2Ueq(C). The

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The diterpenoid alkaloid, delgradine, was previously isolated from Delphinium grandiflorum L. (Deng et al., 1992), and its structure was established from the spectroscopic data. In our recent investigation, it was isolated from Aconitum carmichaeli Debx, and its crystal structure was determined.
The molecular structure of the title compound is shown in Fig. 1. The molecule of the title compound assumes an U-shaped conformation, with terminal benzene rings being approximately parallel and partially overlapped to each other. The molecule contains eight alicyclic and heterocyclic rings. Cyclohexane rings A (C1/C2/C3/C4/C5/C10) and B (C5/C6/C7/C8/C9/C10) adopt chair conformations; six-membered rings C (C8/C9/C11/C12/C13/C14), D (C8/C9/C11/C12/C15/C16) and E (C8/C12/C13/C14/C15/C16) form a bicycle [2.2.2] octane system with the boat conformation for each six-membered ring C, D and E; the six-membered heterocyclic ring F (C6/C7/C8/C14/C20/N1) adopts a screw-boat conformation; while the five-membered rings G (C5/C6/C10/C20/N1) and H (C8/C9/C10/C14/C20) adopt the same envelope conformation.
The crystal structure contains intermolecular O—H···O hydrogen bond between the hydroxy group and aldehyde O atom (Table 1).
