The mediciinal value of Strychnos henningsii plant. Particularly as an appetite stimulant has long been recognised by the indigenous people of Kenya even before this is properly documented in scientific literature The present work involves isolation and purification of the bitter alkaloidal principles present in powdered plant material. Quantitative estimation of the alkaloidal content, in each morphological part of the plant was done and the result compared with that of closely related species. Strychnos nux vomica, an officiall drug in several pharmacopoeia. Examination of the isolated alkaloidal was done using thin layer chromatography (TLC) and gas, liquid chromatography (GLC) to deter¬mine the number of alkaloids present in the plant. The median lethal du-e (I.D) in rats and the bitterness threshold in humans for the isolated alkaloidal rnixture were determined and compared with those reported for S, nux vomica. Result-, of this work indicate that S. henningsii can be substitute for S. nux vomica as an apettite stimulant
