Abstract Phytochemical study of the whole plants of Sedum sarmentosum Bunge (Crassulaceae) led to the isolation of thirty-six constituents, including sixteen megastigmanes (1–16), seven sterols (17–23), five lignans (24–28), three triterpenoids (29–31), three phenols (32–34), one flavonoid (35), and one glycoside (36). The chemical structures of these metabolites were elucidated by NMR spectroscopy and compared with literature data previously reported. This is the first confirmation of the presence of eleven compounds (4, 15, 16, 18, 19, 22, 24–26, 28, 32) isolated from the family Crassulaceae, one compound (3) from the genus Sedum, and two compounds (17 and 33) from S. sarmentosum. Furthermore, the chemotaxonomic significance of these ingredients from the whole plants of S. sarmentosum were discussed in detail.

景天全草化学成分及其化学分类学意义

摘要 对 Sedum sarmentosum Bunge (Crassulaceae) 全植物的植物化学研究导致分离出 36 种成分，包括 16 种大头花 (1-16)、7 种甾醇 (17-23)、5 种木脂素 (24-28)、3三萜类化合物 (29–31)、三种酚类 (32–34)、一种黄酮类化合物 (35) 和一种糖苷 (36)。这些代谢物的化学结构通过核磁共振光谱阐明，并与先前报道的文献数据进行比较。这是第一次确认存在从景天科中分离的 11 种化合物（4、15、16、18、19、22、24–26、28、32）、一种来自景天属的化合物 (3) 和两种来自 S. sarmentosum 的化合物（17 和 33）。此外，详细讨论了来自S. sarmentosum全株的这些成分的化学分类学意义。
