Abstract:
OBJECTIVETo investigate the butanol fraction of the water/acetone extract and isolate of the new flavonoids from Launeae arboescens.
METHODSThe compounds were isolated by liquid chromatographic methods and their structures were identified by using spectroscopic analysis.
RESULTSTHE ISOLATED COMPOUNDS WERE IDENTIFIED AS: 7-O-[α-rhamnopyranosyl 4',5,6-Trihydroxy flavone 1,4',5'-Di-Methoxy 7-(5″-Me Hexan)1-oyl flavanone 2, 3″-isopropyl pyrano [1″:7,4″:6] 3',4',5',5-Tetrahydroxy flavanone 3,5,4',5'-Tri-Hydroxy 7-(3″-Me butan) -yl flavanone 4, 5,7-Dihydroxy-2',4',5' -trimethoxy-isoflavanone 5,5,6,7,4'-tetrahydroxy flavonol 6,7-O-[α-rhamnopyranosyl-(1->6)-β-glucopyranosyl]- 4',5,7-tri-hydroxy-flavanone 7,7-O-[α-rhamnopyranosyl-(1->6)-β-glucopyranosyl] 3',5-Dihydroxy 4'-Methoxy flavanone 8.
CONCLUSIONSThe presence of different types of bioactive flavonoids in Launeae arboescens extract can explain the large ethnopharmacological uses and the potential activity of this medicinal plant.
