Y. Takemura et al., STUDIES OF THE CONSTITUENTS OF DOMESTIC CITRUS PLANTS .22. 2 NEW ACRIDONE ALKALOIDS FROM A CITRUS PLANT, Heterocycles, 41(1), 1995, pp. 187-190
Two new acridone alkaloids, named furoparadine (1) and trans-dihydroxy
citracridone-I (2), were isolated from the root of Marsh grapefruit (R
