Phytochemical investigation of Cydonia oblonga Mill. collected in Xinjiang province, China, led to the isolation and identification of three new dibenzofurans (1-3) along with one known compound (4). Their structures were elucidated based on HRESIMS, spectroscopic data (IR, UV, 1D, 2D NMR) and X-ray diffraction analysis.
