The spectroscopic structure elucidations of five new acridone alkaloids named yukocitrine (1), yukodine (3), yukodinine (4), grandisine-111 (6) and pummeline (7) from some W plants were described. Our studies of the constituents of several species of genus iXLm3 Plants (Rutaceael have resulted in the isolation of many kinds of acridone alkaloids and c~umarins.~ We wish to describe the isolation and structure elucidation of five new acridone alkaloids, yukocitrine (1), yukodine (3), yukodinine (4), grandisine-111 (6) and pummeline (7) from the roots of some plants.
