Preliminary studies on the content of flavonoids and triterpenoids were conducted of 27 families, of 66 genera, on 90 samples of 70 species of plants spread and cultivated in Georgia. 29 species have been investigated for the first time. Promising plants have been identified. Some of them are devoted to deep phytochemical studies. From the analyzed objects, the following families are distinguished by their flavonoid content: Ericaceae, Labiatae, Leguminosae, Malvaceae, Polygonaceae, Rosaceae, Scrophulariaceae, Tiliaceae, Umbelliferae, Verbenaceae; And in terms of triterpenoids, families are of particular interest: Apocynaceae, Capparaceae, Caprifoliaceae, Caryophyllaceae, Compositae, Ericaceae, Labiatae, Leguminosae, Oleaceae, Rosaceae, Scrophulariaceae, Thymelaeaceae, Umbelliferae. A flavonoid identified as quercetin-3-O-α-L-rhamnopyranosyl-(1®6)-β-D-glucopyranoside - rutin is obtained from the leaves of Capparis spinosa L.
