Diterpenoids and phenolic analogues from the roots of Aralia continentalis

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.

Automated summary

Two new compounds, including a nor-pimarane diterpenoid (continentanol) and a phenolic derivative (aralianic acid), along with known compounds, were isolated from the roots of Aralia continentalis. Structural elucidation was achieved through spectroscopic data interpretation, and known compounds were identified by comparing their spectra with reported values.
