Abstract

Two hitherto unknown highly modified abietane diterpenoids, namely salviapritin A (1) and salviapritin B (2), were isolated from the ethanol extract of Salvia prionitis, together with 17 known compounds. Their chemical structures were established by extensive spectroscopic methods (ESIMS, HRESIMS, 1D and 2D NMR) and by comparison of their NMR data with those of related analogues. Salviapritin A is the first example of a trinorabietane diterpenoid possessing an acenaphthylene skeleton from the Salvia genus. Additionally, a plausible biogenetic pathway for salviapritin B is proposed.
