major constituent of the acetone fraction of ethiopian moringa stenopetala leaves

Phytochemical investigation of the leaves of Moringa stenopetala [Moringaceae], a plant widely used in Ethiopian traditional medicine for the control of diabetes and hypertension, afforded the medicinally useful glycoside rutin. The structure was assigned on the basis of spectroscopic methods [UV, MS, 1H-NMR, 13C-NMR] and hydrolytic studies. The rutin content in the dried leaves was found to be about 1%. Although rutin has been isolated from many plant families, this is the first report of its occurrence in the family Moringaceae
