Abstract:
The new diterpenoids, candesalvoquinone, 12- O-methylcandesalvone B, candesalvone B methyl ester with the 3,4-secoabietane skeleton, and candelabroquinone with the abietane skeleton were isolated from the aerial parts of Salvia candelabrum, together with the known compound candelabrone. The structures were established by mass spectroscopy and advanced two-dimensional NMR methods, including 1H-NMR, JMOD, 1H- 1H COSY, HSQC, HMBC and NOESY experiments.
