Secondary metabolites from Marrubium velutinum, growing wild in Greece

Abstract

From the aerial parts of Marrubium velutinum, two new phenylethanoid glycosides, velutinosides III and IV have been isolated together with four known phenylethanoid glycosides, as well as one new acylated flavone and five known flavonoids. The structures of the isolated compds. were established by means of NMR, MS, and UV spectral analyses.
