Six new compounds, including a tetralone1, two xanthones2and3, a flavan derivative4, and two nor-diterpenoids7and8, accompanied by two known flavan derivatives5and6and a known olefine acid (9) were isolated from whole bodies ofKronopolites svenhedini(Verhoeff). The structures of the new compounds were determined by 1D and 2D nuclear magnetic resonance (NMR) and other spectroscopic methods, as well as computational methods. Selected compounds were evaluated for their biological properties against a mouse pancreatic cancer cell line and inhibitory effects on iNOS and COX-2 in RAW264.7 cells.
