Abstract
Four new limonoid derivatives, 1-O-methylichangensin (1), sudachinoid A (2), B (3), and C (4) were isolated from the seeds of Citrus sudachi, together with the known compounds ichangensin, obacunone, obacunoic acid and limonin, and the structures of the new compounds were elucidated based on spectroscopic and chemical evidence.
