The alkali-extract from the fresh and dried leaves and young shoots from Catha edulis (Celastraceae) grown in Palastina, Aden and Athiopia have been examined from Thin Layer Chromatography and Gas Chromatography. There appears no difference in the chemical composition of the fresh and dried plant material and also among the plants from three different origins. The T.L.C. and G.C. examination do not give the same results. In T.L.C. there are two spots; from these one is D-norpseudoephedrin already known for long time as constituent of C. edulis.From the G.C. examination, besides these, the presence of at least 6 more nitrogeneous substances has been indicated. By mass spectroscopic studies, it could not be possible to identify these substances.
