Abstract: In addition to apigenin 7-glucoside (1), luteolin 3'- glucoside (2), luteolin 4'- glucoside (3), and chrysoeriol 7-glucoside (4), a new flavone glycoside (5) was isolated from the leaves of Ginkgo biloba. Its structure was established as tricetin 4'-methyl ether-3'-β-D-glucoside by spectroscopic analysis.
