Abstract From the roots of Salviaprionitis Hance two new diterpenoids, salvinolone and salvinolactone, and two 4,5-seco-5,10-friedo-abietane diterpenoids, 4-hydroxy sapriparquinone and saprorthoquinone, have been isolated and their structures elucidated on the basis of their 1H and 13C NMR spectra.
Salvinolone, saprorthoquinone, and 4-hydroxysapriparaquinone isolated from the roots of Salvia prionitis Hance. were synthesized starting from (+)-dehydroabieticacid via 11,12-dimethoxyabieta-8,11,13-trien-7-one and 12-methoxyabieta-8, 11,13-triene.
