Comparative Pharmacognostical, Physicochemical And Antibacterial Studies On Seeds Of Holarrhena Antidysenterica Wall And Wrightia Tinctoria R.Br.

Author(s): C. I Jolly, Nisha R Mechery

Holarrhena antidysenterica Wall, an ingredient of the formulation Kurchi Bismuth iodide, has often been confused and adulterated with another member of the same family, that is Wrightia tinctoria R.Br. A comparative study was carried out on both the seeds which included pharmacognostical and physiochemical evaluation. The antibacterial screening of the various extracts of the seeds of H. antidysenterica and W. tinctoria were carried out and the chloroform and methanolic extracts of both the seeds were found to possess antibacterial activity. The determination of bitter-value was carried out only on the seeds of H.antidysenterica, since its seeds were found to be bitter compared to the seeds of W.tinctoria which are tasteless.
