Abstract

Verbascum pycnostachyum Boiss & Helder’in çiçekli kısımlarının biyoaktif methanol ekstresinden, dört iridoit glukoziti, okubin1, aju gol2, ajugozit3, harpagozit4 ve bir feniletanoit glikoziti, verbaskozit5 izole edilmiştir. Bileşiklerin yapıları spektral yöntemlerle UV, IR, 1D NMR ve Mass Spektr. tespit edilmiştir. Ajugozit3 ilk defa Verbascum türlerinden elde edilmiştir.

Secondary Metabolites from Bioactive Methanolic Extract of Verbascum pycnostachyum Boiss. & Helder Flowers

Abstract

Four iridoid glucosides, aucubin1, ajugol2, ajugoside3, harpagoside4, and a phenylethanoid glycoside, verbascoside5 were isolated from the flowers of bioactive methanolic extract of Verbascum pycnostachyum Boiss & Helder. The structures of the compounds were determined from spectral methods UV, IR, 1D NMR and Mass Spec. . Ajugoside3 is encountered for the first time from Verbascum species.
