title: Diterpenes and norditerpenes from the roots of Dorystoechas hastata.
abstract: Five compounds, two diterpenoids ferruginol (1), and 6,7-didehydrosempervirol (2) and two norditerpenoids 17-hydroxycryptotanshinone (3), przewaquinone A (4) along with a new norditerpenoid cryptotanshinone 17beta-oic acid (5) have been isolated from the roots of Dorystoechas hastata Boiss. et Heldr. ex Bentham (Lamiaceae = Labiatae) growing wild in Southwestern Turkey (Antalya).
