Aegle marmelos (Rutaceae) is a deciduous shrub or tree and typically known as bael throughout Southeast Asia and has been used as a medicinal plant and a food ingredient. In this study eight compounds were determined to be O-(3,3-dimethylallyl) halfordinol (1), (R)-aegeline (2), (R)-marmeline (3), imperatorin (4), xanthotoxol (5), valencic acid (6), vanillic acid (7) and rutin (8). The chemical structures of the isolates were elucidated through spectroscopic evidence including 1D, 2D NMR, ESI-Q-TOF-MS and optical rotation.
