A new secoiridoid, (1S,5R,8E)-1-butyl-ligstroside aglycon (1), and five known compounds, including ligstroside (2), oleuropein (3), jasminoid D (4), methyloleoside 7-ethyl ester (5), and syringin (6), were isolated from the stem bark of Syringa reticulata (Blume) H. Hara (Oleaceae). Their structures were elucidated using HR-ESI-MS, 1D and 2D NMR spectroscopy, and comparison with the literature.
