Abstract :From the aerial parts of Scutellaria galericulata L., four phenylethanoid glycosides, 2-insert ignore into journalissuearticles values(4-hydroxyphenyl);-ethyl-insert ignore into journalissuearticles values(6-O-caffeoyl);-b -D-glucopyranoside insert ignore into journalissuearticles values(1);, calceolarioside B insert ignore into journalissuearticles values(2);, osmanthuside E insert ignore into journalissuearticles values(3); and martynoside insert ignore into journalissuearticles values(4);, were isolated. The structure elucidations of the isolated compounds were performed by spectroscopic insert ignore into journalissuearticles values(UV, IR, ESI-MS, 1D- and 2D-NMR); methods. Compounds 1-4 demonstrated scavenging properties toward the 1,1-diphenyl-1-picrylhydrazyl insert ignore into journalissuearticles values(DPPH); radical in TLC autographic assays.
Keywords : Scutellaria galericulata, Lamiaceae, phenylethanoid glycosides, radical scavenging activity
