By preliminary analyses, we established the presence of steroid sapogenins in Allium albidum Fisch. (family Liliaceae) growing in the Georgian SSR. These were isolated by the direct hydrolysis of the saponins without previous extraction from the raw material [1, 2]. The sapogenins were extracted from the hydrolysate with petroleum ether and petroleum ether-ethanol (95 : 5). The mixture of unpurified sapogenins was separated by adsorption chromatography on alumina. In addition to paper-chromatographic analysis, the method of thin-layer paper chromatography proposed by us employing talc as the adsorbent and a benzene-ether (7 : 3) system of solvents was used. The sapogenins were detected by means of Mattheus' reagent [3, 4].
