Abstract From the ethanolic extracts of dried seeds of Sterculia lychnophora Hance Pierre (Malvaceae), a total of twenty-two (22) compounds were isolated. These included one lignan (1), three phenylpropanoids (5–6, 21), two flavonoid glycosides (8–9), two sesquiterpenoids (3, 17), two nucleosides (10, 12), three nitrogenous bases (4, 7, 14), three phenolic acids (2, 13, 20), two heterocyclic aromatic acids (11, 16) and two phytosteroids (18–19). For eighteen out of the 22 compounds, there is no report of their presence in S. lychnophora. There is no report of sixteen of them being present in the Sterculia genus, hence the first report. The isolated compounds showed a significant taxonomic relationship between S. lychnophora and other species of genus Sterculia. Compounds 13 and 20 might serve as important taxonomic markers for the Sterculia genus.

摘要 从 Sterculia lychnophora Hance Pierre（锦葵科）干种子的乙醇提取物中，共分离出二十二 (22) 种化合物。其中包括一种木脂素 (1)、三种苯丙烷 (5–6, 21)、两种黄酮苷 (8–9)、两种倍半萜 (3, 17)、两种核苷 (10, 12)、三种含氮碱基 (4, 7 , 14)、三种酚酸 (2, 13, 20)，两种杂环芳香酸 (11, 16) 和两种植物甾体 (18-19)。对于 22 种化合物中的 18 种，没有关于它们在 S. lychnophora 中存在的报告。没有关于其中 16 种存在于 Sterculia 属中的报告，因此是第一份报告。分离出的化合物显示 S. lychnophora 与其他 Sterculia 属物种之间存在显着的分类关系。化合物 13 和 20 可能作为 Sterculia 属的重要分类标记。
