The researches aimed to accomplish the extraction with supercritical carbon dioxide of sulphur compounds from local plants of the Allium genus. The thin layer chromatography enabled the qualitative identification of thiosulfinates (with Rf = 0.201 – 0.486), diallyl thiosulfinate (with Rf = 0.458 on the Allium ursinum L. extracts) and dipropyl thiosulfinate (with Rf = 0.486 on the Allium cepa var. “Rubiniu” extracts, highlighted through a light brown spot).
