A New Phenylpropanol Glycoside and Its Five Known Analogues from Boschniakia rossica

ObjectiveTo study the constituents in the whole plant of Boschniakia rossica.MethodsThe 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.ResultsOne 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).ConclusionAmong 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.
