Panicutin, a New Alkaloid from Aconitum paniculatum LAM. A new diterpene alkaloid, which we named panicutine (2), was isolated from the paniculatine‐containing chemovariety of Aconitum paniculatum LAM. Investigation by spectral methods showed that 2 has the formula C23H29N44 and belongs to the hetidine (1)‐type alkaloids. It has one acetoxy group at C(2) and one carbonyl group each at C (6) and C (11). Copyright © 1982 Verlag GmbH & Co. KGaA, Weinheim
