title: Salvidorol, a nor-abietane diterpene with a rare carbon skeleton and two abietane diterpene derivatives from Salvia dorrii.
abstract: Salvidorol (1), a irregular nor-abietane-type diterpene, was isolated from the aerial parts of Salvia dorrii, in addition to two epimeric abietane diterpenes (2 and 3). This is the first report of a nor-diterpene with an irregular skeleton. The structures were established by high-field NMR techniques ((1)H-(1)H COSY, DEPT, HMQC, HMBC, NOESY and HRMS) and in case of 2 was confirmed by X-ray analysis.
