In the present study, the major flavonoids of white clover (Trifolium repens L.) Sonja were extracted, isolated and identified. The major flavonoids in leaves and stems were the four flavonol glycosides: kaempferol-3-O-{Xyl(1->2)-Gal} (kaempferol-Xyl-Gal), kaempferol-3-O-{Rha(1->6)-Gal} (kaempferol-Rha-Xyl-Gal), quercetin-3-O-{Xyl(1->2)-Gal} (quercetin-Xyl-Gal), and quercetin-3-O-{Rha(1->6)-Gal} (quercetin-Rha-Xyl-Gal).
