CONTENT OF IRIDOIDS IN ELEVATED PART OF <i>TEUCRIUM POLIUM </i>(LAMIACEAE)
Qualitative reactions (with Stahl reagent, Bacon-Edelman reagent) and thin-layer chromatography established the presence of iridoids in the elevated part of <i>Teucrium polium</i> L. Two iridoids were identified: harpagide and harpagide acetate. Quantification of iridoids in the elevated part of <i>T. polium</i> was determined by spectrophotometry using the reaction with hydroxylamine in an alcoholic extraction. The content of iridoids in the elevated part of <i>T. polium</i> in terms of harpagide acetate was 0.51 %.
