Plants of the genus Dictamnus are a source of chemical compounds with different biological activity – alkaloids, bitterness, furocoumarins, saponins, essential oils. In the present work, the qualitative and quantitative composition of components lipids, fatty acids, and pigments isolated from the leaves of Dictamnus caucasicus Fisch. ex Grossh. – is presented for the first time, also of interest for medicine and pharmacology. Plants were selected in the Samara region, on the territory of which D. caucasicus is currently under threat of extinction. Plant extracts were analyzed by high performance thin-layer and gas-liquid chromatography. Identification of polar lipids was carried out using specific reagents – anthrone reagent, molybdenum blue, Dragendorff’s reagent, 0.2% ninhydrin solution. Neutral lipids were identified using an mixture of standards – triacylglycerol (TAG), oleic acid (FFA), cholesterol (ST), diacyglycerol (DAG). It was shown that the main group of lipids contains carbohydrate fragments – glycolipids as structural components. Among phospholipids, a high content of phosphatidylglycerol was found, and in neutral lipids – free and esterified forms of sterols. Polyunsaturated linolenic acid (C18: 3n3) dominates in the composition of fatty acids, and chlorophyll a dominates in the pigment pool.
