As a result of the further study of the alkaloids of Buxus sempervirens L. cultivated in the environs of Kobuleti, Adzhar ASSR, a new alkaloid named O-methylcyclovirobuxine-D (I) with the composition C₂₉H₄₈N₂O was isolated, having mp 231-233°C (ethanol), [α]ₙ +83.52° (s 0.903; chloroform). Its IR spectrum showed absorption bands of cyclopropane ring methylene (3045, 1452 cm⁻¹) and methoxy group (2860, 1275 cm⁻¹). The NMR spectrum exhibited signals from four C-CH₃ groups, two N-CH₃ groups, a methoxy group, and a C-CH₃ group. The mass spectrum confirmed the presence of a methylamine group at the C₂₀ position of the pregnane nucleus. Acetylation of (I) gave N,N'-diacetyl-O-methylcyclovirobuxine-D (II) with composition C₃₁H₅₂N₂O₃, and Hess methylation gave N,N'-dimethyl derivative (III) identical to N,N',O-trimethylcyclovirobuxine-D, leading to the structure of (I) as 16α-methoxy-4,4',14α-trimethyl-3β,20α-di(methylamino)-9β,19-cyclo-5α-pregnane. From the epigeal part of Delphinium confusum M. Pop. collected in the flowering period in the upper reaches of the R. Talas, besides condelphine, virescenine, and 14-acetylvirescenine, a new base (I) with composition C₂₃H₃₃NO₅ (M⁺ 419) was obtained, having mp 99-100°C (acetone). Its IR spectrum showed absorption bands of hydroxy groups (3460, 3620 cm⁻¹), ether bonds (1100 cm⁻¹), and ester carbonyl (1743 cm⁻¹). The PMR spectrum indicated a tertiary C-methyl group, an N-methyl group, a methoxy group, and an acetyl group. The mass spectrum was characteristic of C₁₉-diterpene alkaloids, confirming a hydroxy group at C-1. A one-proton triplet at 4.82 ppm suggested an acetoxy group at C-14. Saponification of (I) yielded a base identical to karakoline, so the new alkaloid was identified as 14-acetylkarakoline.
