Dichapetalum Thouars represents the major genus in the family and comprises 124 species majority of which are found in Africa and the others in Tropical Asia and South America [1,2].
Recent investigation of the roots of Dichapetalum madagascariense has led to the isolation of the dichapetalins [8,9] which hitherto were an unknown class of compounds.
In this present investigation, four triterpenoids were isolated from the stem bark of Dichapetalum madagascriense.
Even though the compounds isolated from the stem bark are known, this is the first time they are being reported in Dichapetalum madagascariense.
However recent investigations of the stem bark of Dichapetalum gelonoides and Balanops australiana  have led to isolation of zeylanol.
The stem bark of Dichapetalum madagascariense Poir was collected in September 1992 from around the surroundings of the Department of Botany, University of Ghana.
Dichapetalin (A) isolated from the root of Dichapetalum madagascariense was also found to be present in the stem bark by co-tlc but not in quantities that could be isolated.
Clear ontogenetic descriptions of homeotic shifts between petals and stamens are Sanguinaria, with an extra whorl of petals (Papaveraceae: Lehmann & Sattler, 1993) and Actaea (Ranunculaceae: Lehmann & Sattler, 1994), petals transformed into stamens in Macleaya (Papaveraceae: Ronse Decraene & Smets, 1990b), stamens occupying the position of petals in Saraca and Swartia of the Leguminosae (Tucker, 1988b), Dichapetalum (Dichapetalaceae: Breteler, 1973; Figs.
26-28) Dichapetalum Dipentodonta- Dipentodon ceae Epacridaceae None Euphorbiaceae Croton, Cluytia, Mercurialis, etc.
