印度油菊（Guizotia abyssinica （L.f.） Cass.）之地上莖部甲醇抽出物，經各種色層分析法分離得到九個類黃酮化合物包括（–）-liquiritigenin （1）、（–）-7,3',4'-trihydroxyflavanone （2）、（–）-7,8,3',4'-tetrahydroxyflavanone （3）、7,3',4'-trihydroxyflavone （4）、quercetin （5）、isoliquiritigenin （6）、butein （7）、okanin （8）及3,2',4'-trihydroxy-4,3'-dimethoxychalcone （9）。這些化合物皆經由質譜及核磁共振光譜的解析而確認其結構。Nine flavonoids, (–)-liquiritigenin (1), (–)-7,3',4'-trihydroxyflavanone (2), (–)-7,8,3',4'-tetrahydroxyflavanone (3), 7,3',4'-trihydroxylflavone (4), quercetin (5), isoliquiritigenin (6), butein (7), okanin (8), and 3,2',4'-trihydroxy-4,3'-dimethoxychalcone (9), were isolated from the aerial parts of Guizotia abyssinica. The structures of these compounds were identified on the basis of their spectral data and comparison with those in the literature. |
