title: 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, (1)H NMR, (13)C NMR, and 2D NMR methods (including HSQC, (1)H-(1)H COSY, HMBC, and NOESY experiments).
