An iridoid glucoside, lamiide (1); 4 phenylethanoid  glycosides, acteoside (2), b-OH acteoside (3), leucosceptoside A  (4) and samioside (5); a caffeic acid ester, chlorogenic acid (6); 2  flavone glucosides, luteolin-7-O-glucopyranoside (7) and  chrysoeriol-7-O-glucopyranoside (8); and a flavanone aglycone,  naringenin (9), were isolated from the aerial parts of Phlomis  syriaca.  The structures of the isolated compounds were elucidated by  means of spectroscopic (UV, IR, 1D- and 2D-NMR, and FAB-MS) methods.   Free radical scavenging activity of the isolated compounds was  determined using the radical 2,2-diphenyl-1-picrylhydrazyl (DPPH),  spectroscopically.
