title: Verbenacine and salvinine: two new diterpenes from Salvia verbenaca.
abstract: Two new diterpenes namely verbenacine (1) and salvinine (2) have been isolated from the aerial parts of Salvia verbenaca. Their structures have been elucidated on the basis of chemical and spectral data as 3alpha-hydroxy-19-carboxykaur-15-ene and 19-hydroxy-12,14-dioxo labda-15,17-diene.
