Abstract
The structure of diospyrol, the anthelmintic principle of fresh fruits of Diospyros mollis GIRFF., was revised to I by the preparation of the derivatives shown in Chart 1 and by their spectral examinations especially by nuclear magnetic resonance (NMR) shown in Table I. The dried fruits, bark, and fresh roots were also examined and the presence of elliptinone (VI), mamegakinone (VII), and 4, 5, 8-trimethoxy-2-naphthaldehyde (XIII) besides triterpenoids, lupeol, lupenone, betulin, and taraxerol, was revealed.
