Abstract
A new acridone alkaloid, 1,3,5-trihydroxy-10-methylacridone (8), and t wo new coumarins, trans-clausarinol (9) and khelmarin-D (11), were iso lated from the root of Yalaha [several hybrid seedlings resulting from a cross of Duncan grapefruit (Citrus paradisi MACF.) x Dancy tangerin e (C. tangerina HORT, ex TANAKA)], and structures were determined on t he basis of spectroscopic evidence. Seventy known coumarins, acridone alkaloids and miscellaneous compounds were also characterized.
