isolation and identification of flavonol glycosides from lathyrus armenus (boiss. & huet)

In the last five decades study on plant secondary metabolites have been increasing. higher plants with a wide range of secondary metabolites have been very important in the search of new therapeutic agents. in this study secondary metabolites of lathyrus armenus (boiss. & huet) which are endemic in turkey, were studied. flavonol glycosides (rhamnocitrin-3-o-rhamninoside, rhamnetin-3-o-rhamninoside, rhamnazin- 3-o-rhamninoside, kaempferol3-o-rhamninoside and, kaempferol-3-o-glucosyl (1→2) rhamnoside) were isolated by different chromatographic methods and identified by 1h, 13c nmr, as well as 2d nmr and mass spectroscopy techniques from ethyl acetate and aqueous fractions of l. armenus’s methanolic extract. this is the first study about secondary metabolites of turkish lathyrus species.
