【摘要】 从银杏(Ginkgo biloba L.) 叶中分离得到5 个黄酮苷类化合物，通过波谱方法鉴定它们的结构为洋芹素-7-葡萄糖苷(apigenin 7-glucoside 1), 木樨草素-?￠-葡萄糖苷(luteolin ?￠- glucoside 2), 木樨草素-?￠-葡萄糖苷(luteolin ?￠- glucoside 3), 柯伊利素-7-葡萄糖苷(chrysoeriol 7-glucoside 4) 和 tricetin ?￠-methyl ether-?￠-b-D-glucoside(5)。其中化合物5 为新化合物化合物3 和4 为首次从该种植物中分得。更多还原

【Abstract】 In addition to apigenin 7-glucoside(1), luteolin ?￠- glucoside(2), luteolin ?￠- 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 ?￠-methyl ether-?￠-b-D-glucoside by spectroscopic analysis.更多还原
