In this study, Teucrium alyssifolium Stapf and Teucrium sandrasicum O.Schwarz which are endemic plants to Turkey were investigated by chemically. From Teucrium alyssifolium Stapf, four new neoclerodane diterpenoids with novel rearranged skeleton having disübstituted furan ring were isolated; alysine /J(l[3,6a-dihydroxy-3, 19- diacetoxy-4a,18;14,16-diepoxy-7-oxo-neo-cleroda-13,15-dien), alysine B (lp/4a,6a-trihydroxy-3a,18,19-tri acetoxy-14,16- epoxy-7-oxo-«eo-cleroda-13, 15-dien), 3-deacetyl -alysine B (ip,3a,4a,6a-tetrahydroxy-18,19-diacetoxy-14,16-epoxy-7-oxo- «eo-cleroda-13, 15-dien), alysine C (3a,6a-dihydroxy- 4a, 18; 1 4, 16-diepoxy-19-acetoxy-7-oxo-»eo-cleroda- 13, 15-dien). In addition, a new flavanone alysifolinone [(5,7,5'(or3')- trihydroxy 3'(or5') methoxyflavanone] and three known flavones cirsiliol (5,3',4-trihydroxy-6,7-dimethoxyflavone), cirsilineol (5,4'-dihydroxy-6,7,3'-trimethoxy-flavone) and 6,7,3',4'-tetra- methoxyluteolin (5-hydroxy 6,7,3',4'-tetra-methoxyflavone) were obtained.158 From the aceton extract of Teucrium sandrasicum 0. Schwarz, three new neoclerodane diterpenes having monosubstituted furan ring and C-10 hydroxyl group were isolated; sandrasicum A (4a,18;15,16-diepoxy-6a,19-diacetoxy- 8p,103-dihydroxy-»eo-cleroda-13(16), 14-dien-20, 12-olide), 6-deacetylsandrasicum A (4a, 18; 15, 16-diepoxy-6a,8(3, 10J3- trihydroxy-19-acetoxy-weo-cleroda-13(16),14-dien-20, 12-olide) and sandrasicum B (4a, 10a, 18,19-tetrahydroxy-15, 16-epoxy- »eo-cleroda-13(16),14-dien-20, 12-olide) and a known flavone cirsimaritin (5,4'-dihydroxy-6,7-dimethoxyflavone). The structures of the isolated compounds were elucidated based on IR, UV, MS, *H and 13C NMR spectral analysis. Particularly, in the establishment of the structures of diterpenoids, the extensive ID and 2D NMR techniques (spin decoupling, APT, selective INEPT, COSY, NOESY, HETCOR, COLOC, HMBC) were used. The absolute streochemistry of alysine A and alysine B was performed by single crystal X-ray analysis. | en_US |
