Two new prenylated stilbenes with an irregular sesquiterpenyl side chain, solomonin B (1) and solomonin C (2), together with four known compounds, glyasperin A (3), isolated for the first time from propolis, kumatakenin (4), macarangin (5) and mangiferolic acid (6) were isolated from ethanol extract of propolis from Fiji islands. The compounds structures were determined based on their spectral data analysis (1D- and 2D NMR, UV and HREIMS) and comparison with literature data. The chemical composition of propolis from Fiji islands was determined for the first time.
