It is widely used in Ethiopian traditional medicine for the control of diabetes, malaria and hypertension. The seeds are used traditionally as water clarifying agent . The ethanol extract of the leaves of M. stenopetala led to the isolation of three medicinally useful glycosides. The compounds were identified to be rutin, 4 -(4' -0-acetyla - L - rhamnosyloxy ) benzylisothiocyanate and 4 -( 4' - 0 - acety! - a - L - rhamnosyloxy)benzaidehyde. 4-(4'-0-acetyl-a-L-rhamnosyloxy)benzylisothiocyanate and 4-( 4'-0-acetyl-a-L-rhamnosyloxy)benzaldehyde are reported for the first time from M. stenopetala. Structure determination was accomplished by means of spectroscopic methods (UV, IR, 1H NMR, MS ) and chemical studies.enMoringa StenopetalaThesis
