The extracts, decoctions and infusions of Verbascum, commonly known as “mullein”, have been used in traditional medicines for centuries in almost all parts of the world. In this paper, a screening of two different extracts of Verbascum phlomoides flowers originating from the Southeast region of Romania is presented. The content of total phenolics and flavonoids from extracts were determined. Al...

Verbascumkurdistanicum Fırat (Scrophulariaceae), is described and illustrated as a new species that is located in Hakkâri, Turkey. In this study, diagnostic morphological characters of this and closely related species (Verbascumoreophilum K.Koch and Verbascumpyramidatum M. Bieb) are discussed. Furthermore, distribution maps for the three taxa are provided.

Extraction process was optimized by single factor and orthogonal experiment (L9 (3 4 )). Moreover, the content determination was studied in methodology. The optimum ultrasonic extraction conditions were: ethanol concentration of 75%, ultrasonic power of 420 w, the solid-liquid ratio of 1:15, extraction duration of 45 min, extraction temperature of 90°C and extraction for 2 times. Saponins conte...

From CH2Cl2 and MeOH extracts of the stems of Cynomorium songaricum RUPR. (Cynomoriaceae), ursolic acid and its hydrogen malonate were isolated as inhibitors of human immunodeficiency virus type 1 (HIV-1) protease, with 50% inhibitory concentrations (IC50) of 8 and 6 microM, respectively. Amongst various synthesized dicarboxylic acid hemiesters of related triterpenes, inhibitory activity tended...
