Two new naphthoquinones from the stem of Diospyros maritima.
Two new naphthoquinones, 2-ethoxy-8'-hydroxyisodiospyrin (1) and 3-ethoxy-8'-hydroxyisodiospyrin (2), together with two known naphthoquinones, 6-hydroxy-5-methoxy-2-methyl-1,4-naphthoquinone and bisisodiospyrin were isolated from the stems of Diospyros maritima. The structures of 1 and 2 were established on the basis of spectroscopic data.
