Abstract:
In the present paper, HPLC method was employed to distinguish phenolic compounds (flavonoids, hydroxycinnamic acids, catechins and coumarines) from the other constituents of the yacon leaves. These substances were identified and quantified after comparison with reference standards. The major components were rosmarinic acid (0.97%), quercetin-3-D-glycoside (0.20%), gallocatechin (1.56%) and umbelliferone (0.05%) among the above mentioned groups of biologically active substances.
