• C-18-DITERPENOID ALKALOIDS

Extensive phytochemical investigation on the whole herbs of Delphinium anthriscifolium var. majus led to the identification of fourteen diterpenoid alkaloids, including three new C-20-diterpenoid alkaloids (anthriscifolsines A-C, 1-3), six new C-19-diterpenoid alkaloids (anthriscifolrines A-F, 4-9), and five know compounds (10-14). Among them, anthriscifolsine A represents a novel C-20-diterpenoid alkaloid characterized by a seco C-ring. The structures of the isolated compounds were elucidated by extensive spectroscopic methods, including HR-ESI-MS, X-ray, and 1D and 2D NMR experiments. Bioactivity of compounds 3-6 was evaluated for their cytotoxicity against the MCF-7, HepG2 and H460 cancer cell lines.
