Chemistry

Methanol and aqueous extracts from the stem bark tested for the presence of flavonoids, phenols, tannins and saponins. [8] Profiles of its compounds include a variety of dihydroxy-trimethoxy(iso)flavone isomers, apigenin, chrysoeriol, eriodictyol, luteolin, and liquiritigenin. [8]

Uses

The chemical compounds of Piptadeniastrum africanum has generated interest among researchers largely because of a wide variety of afflictions plant extracts are used to treat in traditional medicine. [9] Extracts of the species in used to treat gastric ulcers, the Baka people of Cameroon use macerated stem bark extracts in preparations to treat abdominal pains. [9] While some healers use leave extracts as a tonic or as an aphrodisiac. [9] In Congo and Ghana, it is applied in native medicine as a treatment for back pains and sexual asthenia. [9]

Its timber is valued for use in building canoes and in marine and bridge construction. [3]
