摘要
From the aerial parts of Sideritis ozturkii, three new flavonoids, chrysoeriol 7-O-[2
-O-caffeoyl-6-O-acetyl-β-d-glucopyranosyl-(1→2)-β-d-glucopyranoside], chrysoeriol 7-O-[2-O-caffeoyl-β-d-glucopyranosyl-(1→ 2)-β-d-glucopyranoside] and chrysoeriol 7-O-[2-O-p-coumaroyl-6-β-O-acetyl-d-glucopyranosyl-(1→2)-β-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.
