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.

A series of new curcumin analogues were obtained by Claisen-Schmidt condensation of substituted benzaldehydes with cyclohexanone derivatives using the ratio of 1:2 of ketone to aldehyde in dilute ethanolic solution under base catalyzed (NaOH) conditions at room temperature in good yields. The structures of the synthesized compounds were confirmed by data of IR, 1 H NMR, and 13 C NMR spectra.
