Ficus elastica is a species of the plant in the genus Ficus, from the family Moraceae. Ficus elastica, which is the object of our study, has been used for many years in phytodesign, however in terms of medicine, it remains a poorly studied plant. While studying the external signs and chemical composition of medicinal plant raw materials of leaves Fícus elastica, chromato-mass spectrometry was used. During the process of studying, some diagnostic signs of Ficus elastica were identified. Chromato-mass spectrometry was used to identify 68 compounds. The maximum amount was accounted for б-D-Glucopyranoside, methyl (28,99%), Phytol (9,90%), 2-Hydroxy-3-methylsuccinic acid (6,93%), Lanosterol (6,13%), Hydroquinone (5,55%), 9,12,15-Octadecatrienoic acid, ethyl ester, (Z,Z,Z)- (4,86%), Lup-20(29)-en-3- one (4,17%), 1,2-Benzenediol (3,33%), Lupeol (2,95%), 16-Allopregnene-3б,9а-diol-20-one 3-O-acetate (2,77%), 9-Octadecenamide, (Z)- (2,67%), 9,12,15-Octadecatrienoic acid, (Z,Z,Z)- (2,05%), з-Sitosterol (1,84%), а-d-Lyxofuranoside, methyl (1,57%), Dasycarpidan-1-methanol, acetate (ester) (1,52%), n-Hexadecanoic acid (1,45%), Hexadecanoic acid, ethyl ester (1,33%), 1,8-Dioxacyclohexadecane-2,10- dione, 5,6:12,13-diepoxy-8,16-dimethyl- (1,15%), Vitamin E (0,64%). Identified morphological features of the leaves of Ficus elastica can be used in diagnosis of this species and may help to develop indicators of authenticity for promising medicinal leaves. As mentioned earlier, by means of chromato-mass spectrometry were identified 68 compounds, and the relative percentage of identified compounds was determined using a simple normalization method.
