Abstract Phytochemical study of the aerial parts of Senefelderopsis croizatii Steyerm., led to the isolation and characterization of 14 known compounds, 10 triterpenoids with different skeletons type, friedelane, oleanane, ursanes, lupanes, and cycloartanes, two glycosylates flavonoid, and one iridoid. The chemical structure of those isolated metabolites was obtained by extensive spectrometric, and spectroscopy information of MS, 1D and 2D NMR spectra, IR, and by comparison with literature data previously reported. This is the first phytochemical report of the constituents of this species. These phytochemical data reveal an undeniable chemophenetic relationship with the only other species, Senefelderopsis chiribiquetensis, included in this genus.

Senefelderopsis croizatii Steyerm 的化学成分

摘要 通过对 Senefelderopsis croizatii Steyerm. 地上部分的植物化学研究，分离和表征了 14 种已知化合物、10 种具有不同骨架类型的三萜类化合物、油烷、齐墩果烷、乌萨内、羽扇豆烷和环磷酰胺、两种糖基化黄酮类化合物和一种环环甲醚。这些分离的代谢物的化学结构是通过广泛的质谱、质谱信息、一维和二维核磁共振谱、红外光谱信息获得的，并与以前报道的文献数据进行比较。这是该物种成分的第一份植物化学报告。这些植物化学数据揭示了与该属中唯一的其他物种 Senefelderopsis chiribiquetensis 的不可否认的化学表型关系。
