Publication date: August 2015 Source:Biochemical Systematics and Ecology, Volume 61 Author(s): Ya-Le Niu, Xi Chen, Yi Wu, Hai-Qiang Jiang, Xue-Lan Zhang, En-Tao Li, You-Ying Li, Hong-Lei Zhou, Jia-Guo Liu, De-Yun Wang Twenty-nine compounds, including five acetophenone derivatives (1–5), three phenanthroindolizidine alkaloids (12–14), seven pentacyclic triterpenoids (15–21) and five C21 steroidal sapogenins (22–26), were isolated from the root of Cynanchum paniculatum (Bunge) Kitag. Their structures were determined by spectroscopic methods and comparison with reported data. Moreover, the chemotaxonomic relationships were also discussed. As a result, acetophenone derivatives, pentacyclic triterpenoids and C21 pregnane sapogenins can be recognized as chemotaxonomic markers for Cynanchum genus, and C. paniculatum has close relationships with some species of genus Cynanchum.
