Abstract
Moringa stenopetala is a fast growing tree that grows abundantly in the southern part
of Ethiopia, especially in the Konso area. 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.
