N2  - 7-Methyljuglone (I), isodiospyrin (II), the 2,2'-bmaphthyl-l,l'-quinone (III), and a new quinone (IV), hydroxyisodiospyrin, were isolated from the roots of D. ferreu var. buxfilia. The structure of IV was .elucidated as an S'-hydroxy derivative of isodiospyrin. From the roots of D. muritima plumbagin (v), elliptinone (VI), a new quinone maritinone (VII), and a new tetralone isoshinanolone (VIII)were isolated. Maritinone (VII)was shown to be the 8,8'-dimer of plumagin, and (VIII)is cis-4,8-dihydroxy-3-methyl-lt lone. The naphthoquinones of the genus Diospyros are briefly reviewed
