RESUMEN
Objective: To study the constituents in the whole plant of Boschniakia rossica. Methods: The constituents were separated and purified with chromatographic methods. Their structures were elucidated by spectroscopic methods (1D, 2D NMR, UV, IR, and HRESI-TOF-MS) and chemical analyses. Results: One new phenylpropanol glycoside (1) and its five known analogues were obtained from B. rossica. They were identified as trans-p-coumaryl-(2'-O-β-Z)-glucopyranosyl)-β-D-glucopyranoside (1), salidroside I (2), rossicasin A (3), trans-p-coumaryl alcohol 1-O-β-glucopyranosyl(1→4)-α-rhamnopyranosyl(1→3)-β-glucopyranoside (4), salidroside (5), and acetoside (6). Conclusion: Among the known compounds, compound 2 is firstly isolated from the plants in genus Boschniakia C. A. Mey. ex Bongard. Meanwhile, the 13C-NMR data of 9 and 4' positions in compound 4 are corrected. © 2013 Tianjin Press of Chinese Herbal Medicines.
