Three naphthoquinones, isodiospyrin (I), bisisodiospyrin (II), and 7-methyljuglone (IV), a new tetralone derivative named shinanolone (III) and four triterpenes, taraxerol, lupeol, betulin, and betulinic acid, were isolated from the roots of Diospyros japonica. The structure of shinanolone was elucidated to be 4, 8-dihydroxy-6-methyl-1-tetralone and the application of the dibenzoate chirality rule was attempted for the compound.
