The regenerated S. virgaurea and S. graminifolia, obtained previously by micropropagation from shoot tips and the callus tissue of S. virgaurea, were analysed for phenolic compounds. Preliminary used 2D-TLC methods (fingerprinting) showed the presence of phenolic glucoside--leiocarposide (S. virgaurea only), C-glycosyflavones--schaftoside and isoschaftoside (S. graminifolia), flavonoids and caffeoylquinic acids, similar to the ones reported earlier for naturally growing plants with the exception of the callus tissue. The latter contained predominantly caffeoylquinic acids, which were isolated and identified by NMR as 5-O-caffeoylquinic and 3,5-di-O-caffeoylquinic acids. The content of leiocarposide (HPLC) and flavonoids (colorimetry) in S. virgaurea was determined.
