Anticholinesterase activities of some anthelmintic agents and some medicinal plants

It is known that anthelmintic drugs are potent cholinesterase inhibitors. A biochemical system for measurement of anticholinesterase activity of chemical agents and some reputed medicinal plants was established. Some of Myanmar medicinal plants were found to be cholinesterase inhibitors. Lettokegyi, an antidysenteric medicinal plant which was found to contain high anticholinesterase activity, can therefore be considered as a potential anthelmintic drug.
