Abstract

By analysis of the 1H-, 13C-, and 2-D-nmr spectra (DEPT, 1J-HETCOR, 2,3J-HETCOR, HOMCOR) of a new alkaloid, Guan-fu base Z, from Aconitum koreanum its structure was determined to be that of 2-isobutyryl-14-hydroxyhetisine. All the carbon and all but two of the hydrogen resonances could be assigned.
