From the roots of Salvia montbretii six new diterpenoids were isolated
in addition to eleven known compounds. The new compounds were establi
shed as salvibretol (1), 1-oxosalvibretol (4), 6-hydroxysalvinolone (5
), 7-hydroxytaxodione (6), 7,7'-bistaxodione (7), and 11,11'-didehydro
xy-7,7'-dihydroxytaxodione (8), using 1D and 2D NMR techniques.
