AI Article Synopsis
- Five new flavonoid compounds were identified from Moringa oleifera leaves, including various kaempferide and kaempferol glycosides.
- The isolation process involved a methanolic extract of the leaves, which also yielded several known compounds like kaempferol and quercetin.
- The structures of these compounds were confirmed through spectroscopic techniques and comparisons with existing scientific data.
Article Abstract
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-glucoside-7-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.

Sodium valproate- a salt of valproic acid (VPA), is an anticonvulsant used in the treatment of epilepsy and a range of psychiatric conditions that include panic attacks, anxiety, post-traumatic stress, migraine and bipolar disorder etc. VPA can cause direct damage to many tissues due to accumulation of toxic metabolites. Nowadays, phytochemicals are amongst the best options for the treatment of diseases.
