Rapid-resolution HPLC/DAD/MS separation (in less then 1 min) was optimized for determination and identification of isoflavones in fmol quantities and submicrolitre sample volumes. Method was verified using real samples of soya, Trifolium pratense, Iresine herbstii and Ononis spinosa. Pseudobaptigenin glucoside, irilone, prunetin, texasin, tlatlancuayin and other isoflavones, in addition to aglycones of isoflavones and their -glucosides and malonyl- and acetyl- derivates, were identified in the extracts
Rychlá separace pomocí HPLC/DAD/MS (pod 1 min) byla optimalizována pro stanovení a identifikaci isoflavonů v rozsahu fmolů a v objemech pod jeden mikrolitr. Metoda byla ověřena na reálných vzorcích soji, Trifolium pratense, Iresine herbstii a Ononis spinosa. Kromě glykosidu pseudobaptigeninu, irilonu, prunetinu, texasinu, tlatlancuayinu a dalších isoflavonů byly v extraktech identifikovány i jejich aglykony, -glykosidy, malonyl- a acetyl- deriváty
