Abstract
A new, simple and rapid solid-phase extraction method for the determin ation of furanochromones and pyranocoumarins in Ammi visnaga L. fruits and pharmaceuticals by reversed-phase high-performance liquid chromat ography (RP-HPLC) was developed. The isolation of compounds examined w as carried out on octadecyl BakerBond SPE columns using various concen trations of methanol, acetonitrile and tetrahydrofuran in water. High and reproducible recoveries were obtained. To compare the results of q uantitative analysis a preparative TLC procedure was also elaborated a nd carried out. (C) 1998 Elsevier Science B.V.
