| Abstract: | Three flavonol glycosides were identified in the leaves ofTrillium undulatum. The main glycoside was kaempferol 3-O-α-rhamnosyl-(1→2)-O-α-rhamnosyl-(1→6)]-β-glucoside; the glycosidic sugars and their linkage pattern were quite different from those of the leaf
flavonoids ofT. tschonoskii, T. apetalon, T. Kamtschaticum, T. erectum andT. grandiflorum. Two minor compounds were kaempferol/quercetin 3-O-rutinoside.
