A new alkaloid, polyschistine D (1), a new natural product, benzoyldeoxyaconine (2), and three known alkaloids, benzoylaconine (3), deoxyaconitine (4), and aconitine (5) have been isolated from the roots of Aconitum polyschistum Hand-Mazz collected Sichuan province in China. The structures of polyschistine D (1) and benzoyldeoxyaconine (2) were confirmed on the basis of their spectral data and the chemical correlations. © 1988.
