Two new compounds, including a nor-pimarane diterpenoid (continentanol, 1) and a phenolic derivative (aralianic acid, 2), along with the known diterpenoids (3-11), polyacetylenes (12-15), phenolic components (16-28), and phytosterols (29 and 30), were isolated from roots of Aralia continentalis. The structures of the new compounds were established by spectroscopic data interpretation, particularly HRESIMS, 1 D and 2 D NMR data including HSQC and HMBC. Also, those of the known compounds were identified by spectral comparison with those of the reported values.[Formula: see text].
Keywords: Aralia continentalis; Araliaceae; aralianic acid; continentanol; nor-pimarane diterpenoid.
