Abstract:
Four plants routinely used for medicinal purposes by Native Australians were screened for various biological activities. Methanol extracts of Eremophila maculata, Acacia auriculoformis and Acacia bivenosa exhibited antibiotic effects, while Eremophila alternifolia yielded an extract that induced significant changes to the heart activity of spontaneously hypertensive rats. We report on these biological activities.
