Two new abietane-type diterpenoid o-quinones, 7beta-methoxyabieta-8,13-diene-11,12-dione-(20,6beta)-olide (rosmaquinone A) (1) and 7alpha-methoxyabieta-8,13-diene-11,12-dione-(20,6beta)-olide (rosmaquinone B) (2), together with six known compounds were isolated from the aerial parts of Rosmarinus officinalis L. The structures of the new compounds were determined by extensive spectroscopic analysis, including IR, UV, HR-EIMS, 1D and 2D 400 MHz NMR data (1H, 13C NMR, DEPT, 1H-1H COSY, HMQC, HMBC and NOEs).
