Abstract
Three diterpenoid alkaloids were obtained from the C_6H_6 extract of the root of Aconitum excelsum. Their structures were identified on the basis os spectral data (MS, IR, ~1HNMR, ~13CNMR, DEPT) and physico-chemical properties as lappaconitine (I), ranaconitine (II) and ranaconitine (II). Compunds II and III were obtained for the first time from this plant. Compounds I and II exhibited analgesic and antiarrhythmic activities, as documented in literature reports.
