Article abstract of DOI:10.1016/0031-9422(94)00634-6

From the aerial of Sideritis syriaca a new flavone glycoside, 5,8,3'-trihydroxy-4'-methoxyflavone 7-(6"'-O-acetylsophoroside) was identified to gether with apigenin 7-(6"'-p-coumaroylglycoside) and apigenin 7-(4"'-p-coumaroylglucoside) which are reported for the first time in the genus Sideritis.The compounds were characterized using 1H NMR, 13C NMR, MS and chemical methods. - Key words: Sideritis syriaca; Labiatae; acylated flavone glycosides; 5,8,3'-trihydroxy-4'-methoxyflavone 7-(6"'-O-acetylsophoroside); apigenin 7-(6"-p-coumaroylglucoside); apigenin 7-(4"-p-coumaroylglucoside).
