Abstract:
Two guaiane-type compounds, nardoguaianone J and K (1 and 2) and two aristolane-type compounds, kanshone F and G (3 and 4), were isolated from Nardostachys chinensis roots. The structures including the absolute configurations were elucidated by spectral means and by comparison of their CD spectra.
