ChemInform Abstract: Further Furoclerodanes from Teucrium “maghrebinum”
2010
Two more pairs of C-12 epimeric neoclerodanes were isolated from the aerial parts of Teucrium “maghrebinum” (Teucriumpolium subspecies still unidentified). They are the known teukotschyn 1, the new 12-epi-teukotschyn 2, the new teughrebin 3 and the new 12-epi-teughrebin 4. The structures of the new products were elucidated mainly by spectroscopic methods.
Neoclerodane Diterpenoids from Teucrium maghrebinum
2000
Eight neoclerodane diterpenoids were identified in the extract of the aerial parts of Teucrium maghrebinum. Three of these, 12-epi-teucjaponin A (1), 12-epi-montanin D (2), and 12-epi-montanin B (3), are new natural products, whereas five, teucjaponin A, montanin D, 19-deacetylteuscorodol, teusalvin C (4), and montanin B, are already known. These eight compounds form four pairs of epimers at carbon C-12.

Analysis of Essential Oil from Teucrium maghrebinum Greuter et Burdet Growing Wild in Algeria
2009
The chemical composition of the essential oil obtained from aerial parts of Teucrium maghrebinum growing wild in Algeria was analyzed by GC and GC-MS. Among the 66 identified compounds, δ-cadinene (12.7%), germacrene D (11.4%), γ-cadinene (9.5%) and 4-vinyl guaiacol (4.0%) were the most abundant. The oil is strongly characterized by the presence of sesquiterpenes (61.5%), particularly hydrocarbon sesquiterpenes (49.6%).
