title: New C20-diterpenoid alkaloids from Delphinium laxicymosum var pilostachyum.
abstract: From the whole herb of Delphinium laxicymosum var pilostachyum, three new C20-diterpenoid alkaloids, laxipilostine, laxipilosdine, and laxipilosline (1-3), were isolated, together with fourteen known diterpenoid alkaloids. Their structures were determined by extensively interpretation of their spectroscopic data (1D- and 2D-NMR, MS, and IR).
