Utiliztion of Halophytes as a Source of Pharmaceutical Candidates

Recently, the scientific interest and the economic significance of halophytes has been highly demanding due to medicinal and nutraceutical potential of its bioactive compounds. A xero-halophyte Bassia indica. is a very cheap source of natural entities without any investigation.In this study, a new acylated flavonol tetraglycoside, rare flavonol triglycoside, new alkaloid , alongside with new seco-glycosidic oleanane saponin with 2'R,3'S stereocenters, were isolated from the aerial parts of Bassia indica. The study also reported an optimal separation of rare occurring R-isomer lignanamide, in addition to its known corresponding S-isomer. The acetylcholinesterase inhibitory activity of the isolated compounds was evaluated.
