Chemotaxonomic importance of diarylheptanoids and phenylpropanoids in Saxifraga tangutica (Saxifragaceae)

Publication date: June 2017 Source:Biochemical Systematics and Ecology, Volume 72 Author(s): Jun Dang, Li-jin Jiao, Wei-dong Wang, Jin-jin Pei, Yan-duo Tao, Yun Shao, Li-juan Mei, Qi-lan Wang, Li Zhang A phytochemical investigation of Saxifraga tangutica led to the isolation of 11 compounds, including eight diarylheptanoids (1–6, 10 and 11) and three phenylpropanoids (7–9). The chemical structures were established by extensive analysis of their MS and NMR spectroscopic data or comparison with literature data. In the present research, we report the isolated compounds 1–11, for the first time, in the species S. tangutica. Moreover, compounds 1, 2 and 4–11 have not been reported from any species in Saxifragaceae family. Furthermore, we discuss the chemotaxonomic significance of the isolated compounds.
