Özet

From the aerial parts of Teucrium creticum L. (Lamiaceae) eight compounds, 1 – 8 were isolatedusing chromatographical methods. Based on the results of spectroscopical analysis such as UV, 1D-NMR (1H-,13C-NMR, DEPT-135), 2D-NMR (COSY, HSQC, HMBC, NOESY) and HRMS, the structure of the compoundswere determined as two iridoids, 8-O-acetylharpagide (1) and teuhircoside (2), two phenylethanoid glycosides,verbascoside (= acteoside) (3) and lavandulifolioside (4), and four neoclerodane-type diterpenoids, teucrin H3 (=19-acetylgnaphalin) (5), teucjaponin B (6), teucretol (7) and diacetylteumassilin (8).
