The chemical examination of the roots of D. oocarpa afforded ten coumpounds on column chromatography and repeated crystallizations, Lupeol, 5-Hydroxy-4-methoxy-2-naphthaldehyde, 4-Hydroxy-5-methoxy-2- naphthaldehyde, 4-Hydroxy-3, 5-dimethoxy-2-naphthaldehyde, β-sitosterol, Plumbagin, Betulinaldehyde, Diospyrin, 8’hydroxyisodiospyrin, Umbelliferone. Isolation of umbelliferone belongs to coumarin is the first time record from this species and also from Diospyros genus. Occurrence of napthoquinones is very common in Diospyros species. The author could isolate these quinines from this species also and thus justified the species. Distribution of napthaldehydes in nature is very rare and this report of occurrence is new to the literature
