From the aerial parts of Sideritis ozturkii, three new flavonoids, chrysoeriol 7-O-[2"'-O-calieoyl-6"'-O-acetyl-beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranoside], chrysoeriol 7-O-[2"'-O-cafeoyl-beta-O-glucopyranosyl-(1 --> 2)-beta-D-glucopyranoside] and chrysoeriol 7-O-[2"'-O-p-coumaroyl-6"'-beta-O-acetyl-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranoside] named as ozturkosides A, B and C, respectively; were isolated, along with three known phenylethanoid glycosides, verbascoside, leucoseptoside A, martynoside and five known diterpenoids, 7-epicandicandiol, linearol, sidol, sideroxol, epoxyisolinearol. The structures were elucidated mainly by spectroscopic methods. (C) 2004 Elsevier Ltd. All rights reserved.
