Phenolics of Moringra oleifera leaves

Five flavonol glycosides characterised as kaempferide 3-O-(2,3-diacetylglucoside), kaempferide 3-O-(2-O-galloylrhamnoside), kaempferide 3-O-(2-O-galloylrutinoside)-7-O-alpha-rhamnoside, kaempferol 3-O-[beta-glucosyl-(1 -> 2)]-[alpha-rhamnosyl-(1 -> 6)]-beta-glucoside-7-O-alpha-rhamnoside and kaempferol 3-O-[alpha-rhamnosyl-(1 -> 2)]-[alpha-rhamnosyl-(1 -> 4)]-beta-glucoside7-O-alpha-rhamnoside together with benzoic acid 4-O-beta-glucoside, benzoic acid 4-O-alpha-rhamnosyl-(1 -> 2)-beta-glucoside and benzaldehyde 4-O-beta-glucoside have been isolated from methanolic extract of Moringa oleifera leaves. Also obtained from the same extract were known compounds, kaempferol 3-O-alpha-rhamnoside, kaempferol, syringic acid, gallic acid, rutin and quercetin 3-O-beta-glucoside. Their structures were determined using spectroscopic methods as well as comparison with data from known compounds.
