Taraxerol (1), scopoletin (2) and (-)-epicatechin (3) were isolated from Kydia glabrescens along with β-sitosterol and β-sitosterol glucoside. The identification of the isolates were made by spectroscopic techniques. In addition, the 13C-NMR assignments of taraxerol were revised, based on 2D NMR data.
