FLAVONOIDS IN THE LEAVES OF TRILLIUM UNDULATUM WILLDENOW .2. STUDIES OF THE FLAVONOIDS OF GENUS TRILLIUM

摘要

Three flavonol glycosides were identified in the leaves of Trillium undulatum. The main glycoside was kaempferol 3-O-alpha-rhamnosyl-(1 --> 2)-O-[alpha-rhamnosyl-(1 --> 6)]-beta-glucoside; the glycosidic sugars and their linkage pattern were quite different from those of the leaf flavonoids of T. tschonoskii, T. apetalon, T. kamtschaticum, T. erectum and T. grandiflorum. Two minor compounds were kaempferol/quercetin 3-O-rutinoside. [References: 11]
