Abstract:
Objective To study the constituents in the twigs and leaves of Rhododendron primulaeflorum. Methods The constituents were separated and purified with chromatographic methods. Their structures were elucidated by spectroscopic methods (1D, 2D NMR, IR, and HR-ESI-MS) and chemical analyses. Results One new phenylpropanol glycoside, 4-hydroxyl-5-methoxyl-phenylpropanol-3-O-β-D-glucopyranoside (1), and its aglycone (2) were successfully isolated from the twigs and leaves of R. primulaeflorum. Conclusion Compound 1 is a new phenylpropanol glycoside. Compounds 1 and 2 are isolated from this plant for the first time.
