Phytochemical study of Fallopia dentatoalata gave seventeen compounds, two sterols (8 and 10), three anthraquinones (5, 16 and 17), one chromone (13), two stilbenes (3 and 4), two amides (11 and 12), six flavonoids (1, 2, 6, 7, 14 and 15) and one fatty acid (9). Their structures were elucidated by spectroscopic methods and in comparison with the reported data. Compound 11 was obtained from genus Fallopia for the first time, and all of the compounds were firstly isolated from F. dentatoalata. The chemotaxonomic significance of these compounds was also discussed, which demonstrated the relationships between F. dentatoalata and some other species of genus Fallopia.

的植物化学研究何首乌dentatoalata得到17种化合物，二甾醇（8和10），三个蒽醌（5，16和17），一个色酮（13），两个芪（3和4），两个酰胺（11和12），6个黄酮类化合物（1，2，6，7，14和15）和一个脂肪酸（9）。它们的结构通过光谱方法阐明并与报告的数据进行比较。化合物11为首次从Fallopia属中获得，所有化合物均首次从F. dentatoalata中分离得到。这些化合物的化学分类意义也进行了讨论，这表明之间的关系F. dentatoalata和其他一些物种属的何首乌。
