Abstract:  Twelve steroid alkaloids were isolated from Buxus sempervirens var. argentea HORT. ex. STEUD. Nine of them: buxtauine-M, cyclobuxamine-H, cyclobuxine-D, cyclobuxophyllinine-M, cyclobuxoviridine-L, cycloprotobuxine-C, cycloprotobuxine-D, cyclovirobuxine-D, and irehine were separated also from other Buxus plants. Structural formula of an alkaloid of molecular weight 386, denominated cyclobuxargentine-G, was postulated on the basis of spectral evidence. Two alkaloids of molecular weight 398 and 426 were characterized by physicochemical constants and spectral data.
