Abstract

The new norditerpene alkaloid uraphine, for which the structure 1 alpha,6 beta-dihydroxy-7,8-methylenedioxy-14 alpha,16 beta,18 beta-trimethoxy-N-ethylaconitane was proposed based on PMR, C-13 NMR, IR, and mass spectral data, was isolated from the aerial part of Delphinium uralense N. The known alkaloids dehydrodelcorine, delpheline, deltaline, deltamine, elasine, deacetylelasine, gigactonine, and lycoctonine were also isolated from the total alkaloids.
