Chemical constituents from Stenosolenium saxatile (Pall.) Turcz. (Boraginaceae)

Publication date: October 2017 Source:Biochemical Systematics and Ecology, Volume 74 Author(s): Xiao-Rong Bai, Na Zhang, Kai Ren, Jian-Ping Xu, Zi-Yan Li, Chun-Hong Zhang, Min-Hui Li Chemical investigation on the whole plants of Stenosolenium saxatile led to the isolation of three naphthoquinones (1–3), five pyrrolizidine alkaloids (PAs) (4–8), and six phenolic acids (9–14). The structure of the isolated compounds was elucidated by different spectrometric methods (1H NMR, 13C NMR and ESI-MS). These results are the first chemical data on constituents of this genus. The chemotaxonomic relationships between the genera Stenosolenium, Onosma, Arnebia, Echium and Lithospermum are also discussed.
