Phytochemical investigation of Stenotaenia macrocarpa Freyn & Sint. (Apiaceae) led to the isolation of ten known compounds: eight flavonoids (1–8) and two furanocoumarins (9–10). The chemical structures of the compounds were elucidated based on 1D and 2D NMR and MS spectra, as well as comparison with the relevant literature data. To the best of our knowledge, this is the first detailed phytochemical study about Stenotaenia macrocarpa and the first report on the isolation of all the compounds from the genus Stenotaenia, and manghaslin (2) and its methoxylated derivative typhaneoside (3) from Apiaceae. The chemotaxonomic significance of isolates was also discussed.

硬脂酸Steenoaenia macrocarpa Freyn＆Sint的植物化学研究。（A科）导致了十种已知化合物的分离：八个类黄酮（1 – 8）和两个呋喃香豆素（9 – 10）。根据1D和2D NMR和MS光谱以及与相关文献数据的比较，阐明了化合物的化学结构。据我们所知，这是首次关于大型硬脂假单胞菌的详细植物化学研究，也是关于从硬脂假单胞菌属，以及manghaslin（2）及其甲氧基化衍生物香叶菊苷（3）中分离所有化合物的第一份报告。）。还讨论了分离株的化学分类学意义。
