Norditerpenoid alkaloids from Delphinium anthriscifolium

Abstract

Two new norditerpenoid alkaloids with lycoctonine skeleton, anthriscifolcones A (1) and B (2), were isolated from the whole plant of Delphinium anthriscifolium var. Majus by extensive column chromatography. Their structures were established by IR, MS, ¹H NMR, ¹³C NMR, and 2D NMR methods (including HSQC, ¹H–¹H COSY, HMBC, and NOESY experiments).
